Computer Networks 1

Computer Network Classification and space Networks

Computer networks will be categorised in many alternative ways. One approach defines the kind of network consistent with the geographical area it spans. native space networks (LANs), as an example, usually span one home, school, or tiny building, whereas wide space networks (WANs), reach across cities, states, or perhaps across the planet. the web is that the world's largest public WAN.

Network style

Computer networks additionally disagree in their style approach. the 2 basic styles of network style are referred to as client-server and peer-to-peer. Client-server networks feature centralized server computers that store email, web pages, files, and applications accessed by consumer computers and alternative client devices. On a peer-to-peer network, conversely, all devices tend to support identical functions. Client-server networks are common in business and peer-to-peer networks are common in homes.

A configuration defines the network layout or structure from the purpose of read of information flow. In bus networks, as an example, all computers share and communicate across one common passage, whereas during a star network, knowledge flows through one centralized device. Common forms of network topologies embody bus, star, ring, and mesh.

Network Protocols

Communication languages employed by laptop devices are referred to as network protocols. otherwise to classify laptop networks is by the set of protocols they support. Networks typically implement multiple protocols and every network supports specific applications. fashionable protocols embody TCP/IP — the one normally found on the web and in home networks.

Computer Network Hardware and computer code

Special purpose communication devices together with network routers, access points, and network cables physically glue a network along. Network operative systems and alternative computer code applications generate network traffic and alter users to try and do helpful things.
