The world of education has changed dramatically in the twenty-first century. Previously, classroom instruction was restricted to the education teaching approach. With the development of the Internet, learning can now take place outside of the classroom and in the palms of everyone's hands.

The Covid epidemic in 2020 will also act as a catalyst for expanding the reach of online education to the general population. In fact, from 2020, online instruction, which was previously exclusive to higher education, will be available in kindergartens and preschools as well.

Only your requirements provide you with a genuine sense of the significance of anything. After the epidemic spread, the need of internet education became clear. Online teaching emerged as a rescuer, rescuing the global education system from the threat of a zero-academic year.

Online education is not a new concept. In 1960, the University of Illinois in the United States published the first reference to online learning in the globe. Despite the fact that the Internet had not yet been established at the time, students began to study by connecting computer terminals to build a network. In 1984, the University of Toronto launched the world's first entirely online course. After 2009, online education became more popular.

Online education has a long history in India. All India Radio and Doordarshan provide a broadcast area for students in schools and higher education institutions to listen to recorded educational programs. At IGNOU headquarters in New Delhi, ISROU used the teleconferencing service for the first time in 1994. It was a one-way video and two-way audio connection through phone lines that allowed students to engage in a variety of on-site engagements.

Teachers and students should be fortunate enough to build so many applications by 2021 that two-way communication will be feasible even on mobile devices. This technical development is the product of millions of people working hard. This is the beginning of a revolution.

The problem currently isn't so much with the technology as it is with the notion of making online education meaningful.

Every option comes with its own set of challenges. This unanticipated surge in demand for online education has created a slew of challenges for professors, students, and even parents.

The degree of computer literacy is the first and most significant obstacle. Without extra training, it is difficult for instructors, students, and elders to begin using a learning management system in a short period of time. Computer literacy has become crucial not just for school-aged and dependent children, but also for their parents.

Staying current on developing educational trends in their various professions and areas of expertise, as well as changing pedagogies, is not difficult, but it takes time and effort, and it may be a greater challenge for instructors.

Teachers, as role models for many, find it challenging to properly manage work and time management due to their many jobs and obligations. Work-life balance has suffered as a result.

For online teaching and learning, not all students and professors will have personal devices. To continue to operate successfully, many of them should share laptops and computers with their parents, siblings, friends, and acquaintances. Some folks may not have access to laptops or desktop computers and may only be able to use mobile devices.

To control the quality of education and evaluation, the greatest difficulty for all educational institutions across the world is to carry out evaluation and assessment.

For online education institutes and colleges, this is the most difficult problem. The problem is not just in teaching and learning, but also in instructors' and students' mental health and motivation. Maintaining self-motivation and the passion of pupils is a difficult task. Isolation, or a lack of connection with the outside world, is a psychological issue that still has a significant influence on instructors' and students' enthusiasm. Other concerns that need to be resolved include data security and privacy.
