Computer networks are the basis of communication in IT. Theyare used in a variety of ways and can include many different types of networks.A computer network is a set of computers that are connected so they can shareinformation. The earliest examples of computer networks arefrom the 1960s, but they have come a long way in the half-century since then.
Computer networks can have differentdesigns, with the two basic forms being client/server and peer-to-peernetworks. Client/server networks have centralizedservers for storage, which are accessed by client computers and devices.
Peer-to-peernetworks are often used for file sharing and communication between computers.The main advantage of using a P2P network is its ability to provide highavailability and fault tolerance. If one computer in the network goes down,others can continue working as if nothing happened.
