Networking : The concept of networking is pretty simple. A couple of computers have some cables strung between them, and send data back and both using electrical signalling over the cable. More or less the same as telephones do or, in a very rough sense, like two kids speaking into tin cans connected by a string.In simple way networking means two or more device can communicate with each other and sharing their respective information with the help of any kind of transmission media (wired or wireless).
Wired : In this scenario you can see that all device are connected with wired transmission media which known as Cable. In wired network, every desktop computer or device should be affixed to
another desktop computers or a main appliance using cables.
Wireless : In this scenario all device connected with wireless media there is no using of any kind of cable. In other words wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and/or microwaves to maintain communications.
Types of Networks
LAN (Local Area Network) : It is a relatively small network covering small areas like a room, an office, a building, a campus etc. If you connect two computers for sharing data, you have a LAN. The number of computers connected on a LAN may be up to several hundreds, but most of the time, LANs are made up of more or less a dozen machines, as the idea behind a LAN is to cover a small area. The diameter of LANs can range from 100 meters to 1 kilometers.MAN (Metropolitan Area Network) : It is a large computer network on the large geographical area that include several buildings or even the entire city (metropolis). The geographical area of the MAN is larger than LAN, but smaller than WAN. MAN includes many communicating devices and provides the Internet connectivity for the LANs in the metropolitan area.
MAN is used to combine into a network group located in different buildings into a single network. The diameter of such a network can range from 2 to 50 kilometers.
WAN (Wide Area Network) : It is a network that exists over a large-scale geographical area. A WAN connects different smaller networks, including local area networks (LANs) and metro area networks (MANs). This ensures that computers and users in one location can communicate with computers and users in other locations. WAN implementation can be done either with the help of the public transmission system or a private network. The diameter of WANs can range more than 50 kilometers
