Computer Network

A computer network is a collection of interconnected devices, such as computers, servers, routers, and switches, that are linked together to share resources and exchange data. 

These networks can be classified into different types, such as local area networks (LANs), wide area networks (WANs), and the internet. 

They can also be classified by their physical layout, such as wired or wireless networks, and by their functional characteristics, such as client-server or peer-to-peer networks
