The rapid evolution of microprocessor technology was witnessed by people in the 1970s and 1980s. Moreover, a major acceleration was brought in the 1980s by the expeditious development of the microprocessor which was also known as the replacement by micro-based alternatives of traditional minicomputers and mainframe. Users were also driven by this trend to low-cost solutions based on multiple microprocessor-based systems, network servers, LANs, and PCs. The beginning of the LAN and micro-based PC and the ending of the first era of computer systems was marked in the 1980s. In the last half of the 20th century, the fastest development was experienced by computer technology in contrast to other technologies. This paid huge contributions to the social and economic developments throughout the globe and changed the lives of human beings significantly.

In the second half of the 1980s, rapid growth was witnessed in the LAN technology. In the early 1990s, the speedy development of WANs – Wide Area Networks was led by the internetworking of LANs. However, in 1969 only, the foundation of the Internet was established by the project, ARPANET. Further, in the late 1980s, personal computers became quite easier and cheaper to use and the Internet emerged as the network of networks. The Internet further became quite famous in the 1990s and was embraced by people of various backgrounds and cultures. Through implementations of the FTP (File Transfer Protocol) information used to transfer to the local site from a remote host.

The sharing of resources was facilitated by the existence of the Internet amongst participating organizations that involved private corporations, educational institutions, and governmental agencies. Greater opportunities were also provided by the Internet as a fundamental framework of national and global information structure for reshaping and improving interactions among businesses, citizens, and government. Further in the 1990s, the use of information technology was brought by the rapid popularisation and development of Internet technology into a new era. Thereby within the past 10 years, the important advances of the information age (e-society, e-government, and e-commerce) have been booming.
