Evolution of Computing

Evolution Of Computing:

    The era of computing started with the use of stand-alone computers to carry out different
computing operations. These computers were isolated and not connected to each other.

Eventually as the years passed, the growth of computing expanded in multiple diverse fields
such as business, education, and military due to quick data processing. With such a huge
expansion, organisations felt the need of sharing the processed data among their people
to save tie and effort. This marked the beginning of computer networks. Organisation
began to connect their computers and share data among st their people. These networks
are as follows:

• Local Area Network (LAN)
• Metropolitan Area Network (MAN)
• Wide Area Network (WAN)

LAN refers to a computer network in a small geographical area such as office, home, or
school. MAN refers to a network that covers a city. WAN refers to a network that connects
LAN's and MAN's across the globe.
