Role and impact of digital technologies in E-learning amidst COVID-19 pandemic

ABSTRACT

Research has focused on the implementation of E-Learning amidst the COVID-19 pandemic. During COVID-19, the school and educational institutions were closed due to lockdown. During this period the classes of students are taken online. The digital technology used for e-learning during the COVID-19 pandemic has gained popularity in a very short period. Online classes are taken using Microsoft team, any desk, Zoom, WhatsApp applications. Educational contents are transferred frequently over the internet. Research is considering the impact of e-learning amidst COVID-19 and considering issues such as performance and security during transmission of digital content. The education is provided over cloud environment in a more secure manner with better performance. It has been observed that there have been several kinds of research in the area of cloud computing to provide online education. Issues in such research are performance and security of data. There is a need for a high-speed network to transfer educational content from one place to another. The educational contents needed to be secured and compressed at the time of data transfer. Cloud computing applications and the role of the cloud in e-learning are considered during research. The proposed work is supposed to integrate the proposed mechanism in the educational module. The proposed system is supposed to be secure and fast because data is compressed first then data is encrypted on the sender side. On receiving end the data is decrypted and decompressed. Delay in transmission issue is resolved because the size of data is less during transmission. Moreover, the packet dropping ratio gets reduced. The probability of cracking encrypted files also gets reduced as the data is encrypted after compression. © 2021 IEEE.
