Sustainable Operations and Computers

One of the fundamental components of the United Nations’ sustainable development 2030 agenda is quality education. It aims to ensure inclusive and equitable quality education for all. Digital technologies have emerged as an essential tool to achieve this goal. These technologies are simple to detect emissions sources, prevent additional damage through improved energy eﬃciency and lower-carbon alternatives to fossil fuels, and even remove surplus greenhouse gases from the environment. Digital technologies strive to decrease or eliminate pollution and waste while increasing production and eﬃciency. These technologies have shown a powerful impact on the education system. The recent COVID-19 Pandemic has further institutionalised the applications of digital technologies in education. These digital technologies have made a paradigm shift in the entire education system. It is not only a knowledge provider but also a co-creator of information, a mentor, and an assessor. Technological improvements in education have made life easier for students. Instead of using pen and paper, students nowadays use various software and tools to create presentations and projects. When compared to a stack of notebooks, an iPad is relatively light. When opposed to a weighty book, surﬁng an E-book is easier. These methods aid in increasing interest in research. This paper is brief about the need for digital technologies in education and discusses major applications and challenges in education.


Introduction
Sustainable development includes social well-being, which depends on education.Information technology has emerged to spread shared knowledge and is a primary driving force behind education reforms.The introduction of new technology-assisted learning tools such as mobile devices, smartboards, MOOCs, tablets, laptops, simulations, dynamic visualisations, and virtual laboratories have altered education in schools and institutions.The Internet of Things (IoT) is proven to be one of the most cost-effective methods of educating young brains.It is also a robust mechanism for integrating a world-class learning experience for everybody [1][2][3].Educational technology businesses are continually attempting to create novel solutions to expand access to education for individuals who cannot obtain adequate educational facilities.Social media as a learning tool has come a long way.Large numbers of teachers and students use social media as an essential element of the overall e-learning experience.It is a critical venue for exchanging information about crucial topics these days.Aside from the ability to communicate information anywhere, at any time, social media sites are also a fantastic easy technique for teachers to determine students' learning of the presented content quickly and whether more explanation is required [ 8 , 9 ].
Digital technologies influence agricultural operations, and they will soon revolutionise how farming is done in developed countries, reducing our dependency on pesticides and substantially cutting water use.COVID-19 Pandemic, lockdown, and quarantine are three concepts that have recently entered our lexicon.People worldwide are aware of the catastrophe caused by the coronavirus epidemic.In this crisis, digital technologies are at least keeping the educational system afloat.Students are learning from the convenience of their own homes [ 10 , 11 ].Integrating technology into education provides students with an engaging learning experience, allowing them to remain more interested in the subject without being distracted.The utilisation of projectors, computers, and other cutting-edge technical gear in the classroom may make studying fascinating and entertaining for students.Student learning can become more dynamic and engaging by establishing tasks in class that incorporate technology resources, oral presentations, and group participation.Participation can extend beyond verbal communication as well [12][13][14][15].
From the environmental impact of using less paper for handouts and books to the time savings and convenience of research, digital learning is a wonderful way to cut costs, better utilise resources, promote sustainability and expand both reach and impact for students and teachers.[ 16 , 17 ].Technology is pervasive and intertwined in many aspects of modern life and society.The digital revolution that is sweeping the world has begun to infiltrate the realm of education.It is rapidly transforming the way students learn, and as a result, technology is expected to improve the face of education by making it more inexpensive and accessible [18][19][20].This paper is brief about the applications of digital technologies in education.The next three sections discuss the need for digital technologies in education and brief about the Digital classrooms and applications of digital technologies in education.It is followed by a section on the challenges of digital technologies in education along with a discussion on the future of digital technologies in education.

Research objectives
The primary research objectives of this paper are as under: RO1: -To study the need for digital technologies in education; RO2: -to brief about the importance of digital classroom in education and identify the role of digital technologies applications in education; RO3: -To identify the significant challenges of digital technologies in education.

Need for digital technologies in education
The globalisation of education has already necessitated the application of digital technologies.Online platforms were available for conducting classes, sharing resources, doing the assessment and managing the day to day activities of academic institutions.However, the use of these platforms was proactive.The COVID-19 Pandemic has forced the institutes to adopt the online teaching mode to sustain the education system.Developed countries were well equipped to deal with this crisis.However, developing countries worked hard to meet this requirement.Digital technologies have emerged as the saviour of education in this critical time [21][22][23][24].This global crisis highlights the need to be internationally integrated into the education system.Digital technologies assist in developing abilities that will require students' professional performance, such as problem-solving, thinking structure creation, and process comprehension.They are also preparing for a more unpredictable and changing future in which technology will play a critical role.Students' acquired qualities and abilities will be essential to their professional success.Educational resources and digital tools help to improve the classroom atmosphere and make the teaching-learning process more compelling.Furthermore, they give each educational institution greater flexibility and customisation of curriculum based on the requirements of each student [25][26][27][28][29].
Children might become more engaged in learning if technology is used in the classroom.Because youngsters nowadays are pretty accustomed to the usage of electronic gadgets, incorporating them into schooling would undoubtedly assist in piquing their interest and enhancing their involvement levels.Integrating technology into education provides students with an engaging learning experience, allowing them to remain more interested in the subject without being distracted.The utilisation of projectors, computers, and other cutting-edge technical gear in the classroom may make studying fascinating and entertaining for students.Student learning can become more dynamic and engaging by establishing tasks in class that incorporate technology resources, oral presentations, and group participation.Participation can extend beyond verbal communication as well [30][31][32].
Using computers and other devices in conjunction with digital tools allows students to play a more proactive role and be at the centre of the process [33][34][35].The instructor becomes a guide in this process and can approve learning efficiency.Using the myriad of digital resources, learners may download the required information or upload their content.The web 2.0 technologies (wikis, podcasts, blogs etc.) facilitate learners to generate content, collaborate with others, assess each other work and move toward co-learning.Digital technologies make it easy to use classroom tactics like gamification or approaches like flipped classrooms that optimise learning.Learning landscapes have evolved as a didactic tool that mixes several techniques and enables distinct itineraries to be presented to each student.Technology makes the instruction more inspiring and meaningful [36][37][38].

Digital classroom
Digital classrooms are defined by using electronic devices or platforms such as social media, multimedia, and mobile phones to teach students.With digital technology in education, today's educational landscape has altered for the better or improvements.Digital learning is a learning strategy that employs technology to fulfil the entire curriculum and allows students to learn quickly and rapidly [39][40][41].The digital classroom entirely focuses on teaching via the use of technology.Students use technological or internet-connected gadgets like laptops, tablets, Chromebooks, etc. Instead of taking notes on what the teacher has taught, most of the curriculum is delivered to students online through an engaging and interactive platform.Despite its many facets, education is fundamentally a kind of communication.The internet has resulted in the rise of new communication channels, which have extended the options for the transmission and access to educational information.These media and virtual venues serve as learning facilitators [42][43][44][45].Various features of a digital classroom are shown in Fig. 1 .
Educational applications and websites are used in digital classrooms to assist students in improving their learning experience.Feedback loops and technology are two critical components of a digital classroom.Feedback loops are essential for students to obtain real-time feedback from their teachers.Teachers can use feedback loops to provide feedback depending on many factors such as student, lesson, group, etc. PPTs, video presentations, e-learning methods, online training, and other digital approaches are increasingly used in the teaching-learning process [46][47][48].As a result, classroom instruction is becoming more participatory.Students may now learn many topics on their own by using internet resources and digital classrooms.In schools, colour charts, graphs, and models describe the finest instruction of the class.However, they are now considered old-fashioned methods of giving education.Education in the classroom is no longer restricted to reading books, writing on the blackboard to explain chapters and concepts, and taking notes in their books [49][50][51].

Applications of digital technologies in education
Digital technologies are a powerful instrument that can help improve education in various ways, such as making it easier for instructors to generate instructional materials and providing new methods for people to learn and collaborate.A new era has arrived with the Internet's worldwide reach and many intelligent devices connected to it.Thus, it will be up to instructional designers and educationists to use advanced digital technology's potential to revolutionise education such that effective and efficient education is available to everyone and everywhere [52][53][54].Technology has continued to play an essential role in delivering education to children outside the classroom.Digital learning fosters creativity and gives students a sense of success, encouraging additional learning by thinking outside traditional techniques.All nations were able to adopt remote learning technologies utilising a combination of TV, radio, online, and mobile platforms, which is commendable.These provide easy access to information, easy retention of information, increased storage of information, and improved presentation of information; education became more interactive, easier sharing of knowledge and increased enthusiasm in learning [55][56][57].Table 1 discusses the significant applications of digital technologies in education.
With today's technological growth, instructors must learn to utilise various gadgets, such as smartphones and tablet computers, or face marginalisation.Teachers must also harness all available online resources to ensure that their materials are alive, engaging, and up to date.Technology is more than just playing video games and viewing animated films.The advantages are determined by how students, parents, and teachers use technology to improve education.When technology is used effectively for instructional reasons, the educational experience improves, and students become interested.Making e-learning systems compatible with new smart devices such as phones and tablets has been a significant element in the ease of access and faster uptake of digital learning.Specialised learning goods, such as animation, games, or AI-powered systems designed exclusively for edutainment, are also included.Technology-enabled innovations have helped facilitate learning across age groups and topics.The importance of Big Data and the application of analytics to learning was an essential but generally overlooked part of Education technologies [208,209] .Schools and educational institutions realise the value of comprehensive student and instructor performance data as they extend their usage of virtual classrooms, e-learning platforms, and online exams.

Challenges of digital technologies in education
Educational technology is not without its difficulties, notably in implementation and usage.Issues regarding excessive screen time, the ef-ficacy of instructors' use of technology, and concerns about technology fairness are also raised.The content has become more significant as a result of the COVID-19 problem.Educators must generate and comment on online educational content, encouraging students to analyse a topic from several angles in particular.Furthermore, while some students thrive in online learning settings, others struggle due to various factors, including a lack of support.For example, a student who has previously suffered in face-to-face circumstances may suffer far more in the current situation.These people may have been reliant on services that are no longer accessible.However, online education may provide difficulties for instructors, particularly in areas where it has not been the norm [ 210 , 211 , 212 ].
Some of the reasons for the learning crises are widely known.One crucial factor is the poor quality of instruction.Teachers frequently lack topic expertise and have received little training.There are technology solutions to this, and they could be helpful in both training instructors and instructing students.Technologies can provide in-service training or a combination of online and in-person training.Additionally, there is evidence that instructors require better incentives.They can educate but lack the motivation to do so.Even though education has always extended outside the conventional classroom, the changing circumstances and scale of digital and remote contexts demand significant adaptation, preparation, support, and engagement.Limited or no contact with students, rethinking engagement, reaching, teaching approaches, appropriately addressing a range of unique needs, motivating students, handling conflicting time demands, and coping with constrained settings may contribute to attentive learning and teaching.[ 213 , 214 , 215 ].
There is also evidence that low-tech interventions for "instruction at the appropriate level" can significantly affect learning.Because low-tech solutions are less expensive and funding restricts impoverished nations, careful investigation is required to establish whether high-tech or lowtech solutions are better or not.Teachers are teaching through video, but they are not always teaching better than they would if they were standing in front of a classroom.More massive open online courses are being offered and taken up, but many are not for primary education and do not address the learning issue.It necessitates hardware and connectivity at home, inaccessible to children in low-income homes.Gamification and other strategies may encourage youngsters to devote more time to studying.Finally, consider that effective learning outcomes may be obtained without using education technologies [216,217] .
Some students are having difficulties as a result of this online schooling.Some students come from low-income families and do not have cellphones in their homes; thus, they struggle in school.Millions of youngsters simply do not have access to the internet at home.Students under 15 acquire this complex technology early, yet they struggle with poor vision and backache.Teachers are also having difficulty since some are utterly inexperienced with digital technologies.Nonetheless, they do ev-

Improve teaching productivity
Teaching productivity may be improved by using advanced technological aids, which facilitate better planning, easy and practical learning, quick assessment, better resources, new skills, etc.
[ [58][59][60][61][62] 2. Develop Online libraries Technological advancements have helped create and develop online libraries, which have removed the physical space requirement and facilitated interaction among students, teachers, and researchers from across the globe.Online forums have brought subject specialists to discuss specific topics and evaluate the curriculum, teaching pedagogy, and assessment methods.

Promote Distance learning
In reality, technological advancement has boosted distance learning education.It provides easy access to all learning resources and allows the facility to interact with the instructor conveniently.Teachers may quickly build and manage groups using learning tools and technology such as social learning platforms.
[ Technologies strive to build knowledge, understanding, and skills to ensure that students thrive individually and as a team.Teachers may encourage children's curiosity and inquisitiveness through exciting and instructive material, which has been linked to their academic performance.

Creating Inclusive learning environments
An inclusive learning environment provides an equal opportunity for each student with different ability levels to learn in the same place.Virtual classrooms, video, augmented reality, robots, and other technology tools make the class exciting and create inclusive learning environments that foster collaboration and curiosity while allowing teachers to collect data on student performance.

Developing teamwork and communication skills
Teamwork and communication skills are two crucial attributes that help develop a successful professional.Digital technologies play an essential role in developing these skills.

Solving educational challenges
Students collaborate to solve ongoing educational challenges using online platforms.Hackathons have emerged as a successful event to find the solutions to many challenging problems.Students may express themselves and collaborate on activities by sharing their thoughts and ideas.

Enhanced access to educational resources
Access to educational resources anytime is now possible, seven days a week.Cloud storage, video recording of lectures and availability of notes in a soft copy made it easy for students to access the resources at their convenience.Even parents can access these resources and check the quality of lectures and notes.

Addressing students to completing the syllabus
Computer-assisted learning is the most direct way to support students by helping the teachers complete the syllabus.Students have different baseline learning levels in a classroom, and teachers are frequently driven to teach to the highest stratum, leaving many students behind.These technologies have helped such students in completing their syllabus.

Transformed the innovative way of learning
Digital technology has transformed the way pupils learn in the classroom, even though the education industry has evolved.Students are taught digital skills and encouraged to bring computers to class so that they may access a variety of materials quickly.Students are encouraged to explore information in new and exciting ways through educational applications and programmes.Teachers can use interactive whiteboards and classroom clickers to introduce and reinforce topic knowledge while changing their teaching approaches.Reporting and assignment management have changed substantially rather than generating real report cards to send home once a term.
Instructors may now assign, collect, and grade work using specialised learning management systems, keeping students and parents informed about their progress.

Arithmetic classes
Digital tools help students listen to math classes and respond by typing, scribbling, or dictating their remarks.As the school year progresses and the years pass, digital technology will be employed to make math education through practice more accessible to all students, regardless of ability or learning environment.These technologies also give pupils the option of studying or demonstrating their math skills in various ways.Because the learning environment is more dynamic than it has ever been, today's students are very different from those for whom the educational system was created.As technology improves, classrooms are being remodelled and reimagined in numerous ways to meet the increasing expectations of modern digital learners.

Convenient teaching and learning
COVID-19 has heightened the role of technology in the lives of billions of students around the world.Regardless, digital technology is the only way for the educational institution to thrive in this challenging day.Internet-based learning resources are now widely available.Furthermore, the AI system has significantly enhanced learning.
Intelligence can identify a student's strengths and weaknesses on its own.They have a customised learning strategy to ensure that each student reaches their full potential.At times, they can even be more rewarding than classroom education.Coronavirus has shaken the entire planet, and people are progressively acclimating.As a result of the Pandemic, office staff are working from home.This situation affects everyone, and underprivileged people find it challenging to go about their daily lives.On the other hand, students can continue their education at home by employing digital technologies.
Reduce the requirement for a blackboard The class with the most advanced technologies is now considered the best class.The use of technology in city schools has grown significantly in recent years.Blackboards have been replaced with PowerPoint presentations, online courses, and videos.Today, all schools incorporate technology into their curriculum in some form.Several schools have digitised their whole education system by recognising the function of digital classes in school.
Because of the advancement of the internet, mobile phones, mobile apps, tablets, laptops, and other gadgets, more and more aspects of today's world are becoming digital.Digital education is replacing conventional education in classrooms in many schools and colleges.

Making classroom instructions interesting
Classroom instruction has become more exciting and participatory due to digital education.Children are becoming increasingly aware of it.They not only listen to what the teacher says, but they also watch it on the screen.It facilitates visual learning for youngsters.The instructional material in practical sessions in digital classrooms lets students pay greater attention to details through interactive online presentations.Students now have more options and control over their learning experiences because of technology in the classroom.Learning technologies have also provided academics with greater freedom in offering lectures or labs.Students can tune in to live-streamed lectures at a given time, whilst others can watch lecture recordings independently if they cannot attend a live session.Furthermore, real-time courses in online learning may provide students with better interests.

Expand knowledge
Students who use digital learning tools and technology are more involved and want to learn more.They may not even realise they are actively learning because they are learning through exciting approaches such as peer education, teamwork, problem-solving, reverse teaching, concept mapping, gamification, staging, role-playing, and storytelling.Because it is substantially more engaging and remembered than big textbooks or one-sided lectures, digital learning delivers a deeper context, a broader viewpoint, and more stimulating activities than traditional teaching strategies.As a result, students can better connect with the learning information.Furthermore, they frequently provide a more exciting and engaging approach to processing information.
Addresses learning gaps By addressing learning gaps early and enhancing growth, each student's capacity to personalise learning sequences will make education more successful.In addition to educators, parents may use interactive activities to increase their child's interest in learning since gamification makes the process more enjoyable and engaging.Parents can use internet learning activities to augment their children's schoolwork.Digital learning tools and technology provide youngsters with fun and a plethora of benefits for their overall development.Digital learning allows students to access more knowledge and ensures that the content is customisable and tailored to their specific requirements.The ability to assist each student in studying at their speed and on their route is the most crucial advantage of digital learning.

Quickly gain information
Educators may quickly exchange information with other educators using digital learning tools and technologies in real-time.The growth of free and open content and tools has produced a sharing economic atmosphere.Classrooms worldwide may collaborate to share ideas and improve learning, experience, and communication skills by adopting digital devices and linked education.These also provide instructors with a fair playing field.Schools may save money while ensuring that all students have equitable access to educational materials.Problem-based learning is emphasised in digital learning solutions and constructive, collaborative learning techniques that direct students' attention to a real-world approach to learning.In elementary, secondary, and high schools, digital learning tools and technology support students in developing problem-solving skills, understanding emerging technologies, and self-motivation, which prepare them for future education and work.

E-books
Students can now discover information more quickly and correctly with advances in technology.Search engines and e-books are replacing traditional textbooks.On the other hand, students may begin to learn how to be responsible in the digital world by introducing technology into the classroom.The class becomes a microcosm of the larger digital environment in which students may practise communicating, searching, and interacting with other digital citizens.Technology has also increased communication and cooperation opportunities.Classrooms have traditionally been isolated, with cooperation confined to other students in the same classroom or building.Today's technology provides types of communication and collaboration previously unimaginable.Kids can share their knowledge with students in other schools around the country.

MOOC Platform
Students benefit from MOOCs to improve their credentials and talents.It enables millions of learners who cannot afford an education to enhance their employability by giving them access to various skill-based courses.Thanks to MOOCs, students and working professionals can study at their speed, from anywhere and at any time.Furthermore, some lecture courses offered through this platform result in a certificate that institutes and enterprises recognise as a step in the right direction.According to recent trends, online classes delivered through the MOOC platform have a sizable market.Students enrolled in professional studies and working executives are more motivated to improve their skill set to take advantage of growing job opportunities in specialised industries.MOOC-based personalised learning is becoming more popular.

Video-based instructional learning
Technologies based blended learning with entertainment and video-based instructional education is prevalent among students.This type of teaching-learning medium is highly participatory.This form of teaching style comprises not only audio-video but also instructional applications, podcasts, eBooks, and so on.Children are ecstatic to discover new concepts through these digital platforms.With the internet becoming more economical and accessible, there will be a more significant confluence of digital and conventional teaching-learning methods in the future.Online education provides freely available material for learning, teaching, and research.It enables students to engage with a wide range of study material publicly available on the internet, therefore establishing a self-learning environment.

Increased educational opportunities
The effective use of technology will undoubtedly increase educational opportunities.Students now have access to a wide range of online resources and journals linked to their study themes via their computers and portable devices, allowing them to obtain additional information for their schoolwork.Furthermore, digital platforms provide students with reliable and high-quality data from their PC, anywhere and anytime.Aside from information resources, technology in education allows students to contact academic professionals worldwide.Technology in education is the most significant revolution in teaching that will ever witness.
Access teaching up-to-date material Thanks to recent technological developments, students may now access the most up-to-date teaching.The traditional passive learning paradigm has been challenged, and due to technological advancements, educators can directly involve students in more effective learning methods.

Breakdown all educational barriers
Technology breaks down all educational barriers, allowing students and instructors to communicate in real-time and learn in ways that transcend time and location.Indeed, technology-based classrooms provide students with a unique environment to learn complicated subjects straightforwardly.A complete and rigorous learning experience would add a new dimension to their learning and assist them in achieving academic success.Technology integration starts in elementary school and progresses to high school and higher education.

Offer environmental benefits
Using technology in the classroom offers environmental benefits as well.Institutions can save money on ink and paper by storing vital documents in a single digital place.There is lesser transportation of students and more secondary emissions, but there is no substitute for physical interactions between students and teachers.[191][192][193] 31.

Dynamic learning
Teachers can use technology to create a more dynamic and exciting learning environment.Technology also provides a dynamic classroom environment by digitising textbooks and incorporating links and QR codes to study and assess course subjects.Technologically adept teachers may profit from the advent of new technologies.Software for specialised activities or the establishment of flipped classrooms, for example, is employed.In this scenario, students can watch pre-recorded lectures as homework and arrive at class ready to discuss topics and information.New digital instruments in classrooms necessitate management and training.Teachers must be productive in the classroom and online, using a variety of screens and technological platforms.The internet and other digital technologies, according to teachers, have greatly expanded the number of topics and abilities they must be knowledgeable about, and over half believe their workload has grown as a result.[194][195][196][197] 32.
Reduce teacher workload New technologies are introduced by automating repetitive procedures and elements of the educational process.
There are tools available for developing and grading exams.Most will post the findings to a database, where each student's performance may be easily verified.It takes time to communicate with students and their families.Teachers may use social media and texting to reach out to the entire community and engage in one-on-one conversations with each student and parent.These facilitate online spreadsheets, social network account updating, and contact information organisation.[198][199][200][201] 33.

Assessing students in real-time
Digital technology can revolutionise students' learning experiences in and out of the classroom.Technology allows us new ways of interacting, building knowledge, assessing students in real-time and preparing students for life in an increasingly digital world.Opportunities exist for instructors to reinvent instructional techniques, learn, and work more efficiently to improve wellness.Appropriate technology in an educational environment thus is evaluated for its ability to satisfy educational goals.

Moving to Hybrid teaching & learning
Hybrid Teaching and learning involve the supplementary and complimentary use of Online and Offline teaching and learning.This is the future and an outcome of Education 4.0.
[ [205][206][207] erything possible to educate their children through online classes.College students who take more practical subjects than theoretical subjects face similar challenges because practical knowledge is not attainable in online programmes [ 218 , 219 ].While technology can be considered yet another avenue for cheating, it is possible to design assignments and assessments so that such an occurrence is unlikely.On the other hand, open-book exams can be used to emphasise problem-solving and mastery over retention.Timeconsuming processes such as tracking student attendance and performance can be sped up with automation.Because of their objective nature, engagement tools can assist in expediting grading for writing assignments, conversations, and participation and address typical student inquiries.Without proper information and communication technology equipment, internet/mobile network connectivity, instructional resources, and teacher training, students cannot participate in distant education.Students from resource-poor locations, isolated rural areas, and low-income households are more likely to fall behind.Learners with disabilities or who speak a language other than English at home will require additional individualised assistance.

Discussion
Digital technologies allow students to experience the globe and go to faraway places from the comfort of their computers.Inviting a guest speaker to talk to the class about their expertise is terrific to spice up any lesson plan.Video conferencing systems make it simple to bring a subject matter expert face-to-face to our classroom, no matter where they are.We can easily organise a classroom video conference with kids from an-other institution.Online polls and other digital technologies engage all students, timid kids who would not ordinarily raise their hands in class.Online engagement tools enable checking in with students regularly to solicit input on course materials and assignments.Student insights can also be utilised to identify areas where students may be struggling.Student response systems promote digital citizenship in the classroom by allowing students to participate in class while also being rewarded.Schools serve an essential role in our communities, and their closure has far-reaching consequences for the psychological well-being of many families and children.Digital technologies can easily take up this challenge.Online learning allows students to learn at their speed, pause and rewatch videos, and explore course content independently.
Quizzes are another active learning strategy that education technology may help.Students may begin working on a project together in class and fluidly collaborate, communicate, and bounce ideas off one another utilising social media, interactive whiteboards, and other technology.Physical and social constraints allow students to collaborate from anywhere and at any time.Technology has also enabled students to join in spontaneous discussions and obtain immediate answers to any difficulties or questions regarding a subject.Because of self-paced learning and individual variances, students will virtually always complete their work at various times.When this happens, maintaining students' attention is as simple as giving them access to educational films, course-based games, or interactive learning tools.As a result, faster-paced students no longer need to wait for all of their colleagues to finish before continuing their studies, while slower-paced students are no longer tempted to rush through their work.This Education 4.0 programme will be implemented in future schools to improve education and better prepare the next gen-eration of potential.Further, Artificial intelligence will help driverless cars travel more effectively and reduce emissions.Material scientists are using AI to produce biodegradable plastic substitutes and techniques to clean our seas.Recycling and upcycling may appear to be simple procedures, yet they are highly effective instruments for increasing sustainability efforts.Recycling is a game-changer for sustainability, whether it is consumers reusing bottles to decrease plastic waste or businesses fashioning discarded objects into new goods.

Future of technologies in education
Small, medium and large-scale education technology companies have started proliferating in the future and are offering various new digital solutions to academic institutions.This will improve the quality of digital infrastructure across the country, making innovative educational technology more accessible to larger masses.We foresee the removal of all linguistic boundaries and better Online availability of learning resources in regional languages.E-learning and m-learning programmes provide students and teachers access to a vast pool of information content.While technology will play an essential role in shaping the future of education, ensuring that new teaching tools are used effectively will require a new generation of educators who understand the importance of human connection in the classroom.These can lead to a satisfying and engaging career in education.Students gain the knowledge and skills necessary to employ new educational technology to maximise their advantages for today and in the future.In upcoming years, education trends will ride the tide of growing internet capabilities and network capacity, making it easier to incorporate innovative technology into classrooms.However, there is no complete substitute for offline (classroom) teaching & learning.Thus we have reached the era of hybrid teaching and learning, where both online and offline systems are integrated to enhance the outcomes and are envisaged as an outcome of the implementation of Education 4.0

Conclusion
Digital technology in the classroom refers to various software and gadgets meant to help students with particular accessibility needs.The most effective way to reduce the number of repetitive, time-consuming duties a teacher undertake is to use technology in the classroom.Educational technology applications may save a lot of time and energy by automating or partially automating day-to-day operations like attendance tracking and performance monitoring.Students are taught how to use technology responsibly and strategically, which can help them make decisions and develop self-discipline.Technology in education can help students to prepare for lifelong learning.These technologies provide students with a virtual world and the freedom to access digital knowledge according to their learning styles.Thanks to digital content production tools that customise teaching and learning, students can study at their own pace.The digital classroom uses electronic devices and software to instruct students and incorporates technology into education.A traditional classroom is transformed into a digital classroom through computers and the Internet.Students can learn more efficiently and track their progress with the help of technology and sophisticated equipment.In the upcoming days, these technologies will successfully be implemented in education to enhance the students' digital learning environment and performance.Modern technologies have been instrumental in complicated data analysis and management to make long-term decisions in areas such as climate change, air and water security, biodiversity protection, catastrophe resilience, etc.These technologies refer to innovation that considers natural resources while also promoting economic and social growth.These aim to dramatically decrease environmental and ecological concerns while producing a long-term product.These technologies reduce degradation, pollution, and other negative environmental effects.
