Transcript of A network is a group of two or more computer systems linked

WHAT IS NETWORK ?
A local-area network (LAN) is a computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).
Acronym for campus-area network. An interconnection of local-area networks within a limited geographical space, such as a school campus or a military base.
A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LAN).
Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet.
NETWORK
A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider Internet. This gives users the ability to move around within a local coverage area and still be connected to the network.
Short for Metropolitan Area Network, a data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media.
Short for home area network. A HAN is a network contained within a user's home that connects a person's digital devices, from multiple computers and their peripheral devices to telephones, VCRs, televisions, video games, home security systems, "smart" appliances, fax machines and other digital devices that are wired into the network.
A network is a group of two or more computer systems linked together. There are many types of computer networks, including:
a) Local Area Network (LAN)
b) Wide Area Network (WAN)
c) Wireless Local Area Network (WLAN)
d) Campus Area Networks (CAN)
e) Metropolitan Area Network (MAN)
f) Home Area Networks (HAN)
LOCAL AREA NETWORK
WIDE AREA NETWORK
WIRELESS LOCAL AREA NETWORK
METROPOLITAN AREA NETWORK
CAMPUS AREA NETWORK
HOME AREA NETWORK
CONCEPT OF NETWORKING
Implementing tools and tasks for linking computers so that they can share resources over the network.
