how many types of computer networks explain them
Answers
Two basic network types are local-area networks (LANs) and wide-area networks (WANs).
LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links (wires, Ethernet cables, fibre optics, Wi-Fi) that transmit data rapidly. A typical LAN consists of two or more personal computers, printers, and high-capacity disk-storage devices called file servers, which enable each computer on the network to access a common set of files. LAN operating system software, which interprets input and instructs networked devices, allows users to communicate with each other; share the printers and storage equipment; and simultaneously access centrally located processors, data, or programs (instruction sets). LAN users may also access other LANs or tap into WANs. LANs with similar architectures are linked by “bridges,” which act as transfer points. LANs with different architectures are linked by “gateways,” which convert data as it passes between systems.
WANs connect computers and smaller networks to larger networks over greater geographic areas, including different continents. They may link the computers by means of cables, optical fibres, or satellites, but their users commonly access the networks via a modem (a device that allows computers to communicate over telephone lines). The largest WAN is the Internet, a collection of networks and gateways linking billions of computer users on every contine
Hope this helps you
There are three types of computer network:
MAN , WAN , LAN
1) LAN - LAN stand for local area network. it used at short range such as school, bank
2) MAN - MAN stands for Metropolitan area network . Its network range is about a big city
3) WAN - WAN stand for wide area network. It Connects continent to other continent .it's range is very high.
