What are the types of Computer Network?

A computer network is the interconnection of various computers located at different places. There are different types of network based on their size(Number of devices), data transfer speed and their reach. There are three main category of networks given below:-

• LAN

• MAN

• WAN

LAN:-


LAN stands for Local Area Network. It connects network devices on a short distance. It is group of computers which all belong to same organisation or building. It links the devices in a single office, campus and building. 
In LAN the data transfer speed can reach up to 10 Mbps for an Ethernet network and 1 Gbps for Gigabit network. It can be reach as many as 100 or even 1000 users. 


MAN:-


MAN stands for Metropolitan Area Network.It is a network that interconnects users with resources in an area larger than that of LAN area but smaller than a WAN area. A MAN is made from switches or routes connected to one another with high speed links. It spread over an entire city.  


WAN:-


It is a geographically-dispersed collection of LANs. It is more larger than LAN and MAN network. The speed varies on WAN depending on the cost of the connection. Computer connected to a WAN network are often connected through public network like telephone system. They can also be connected through leased line and satellites. WAN provides a long distance transmission of data, video,voice and image information over large geographical area like a country, continent or even the whole world. Internet is the most well known WAN network. 

Define Networking?

What is Networking?

A network is a collection of computers, servers, and components. These allows for the easy flow of data and use of resources between one another. Networking is the practice of communicating two or more computers or devices for the purpose of sharing data. Networking helps the communication among multiple computers easily. With the help of computer networking the user access may be restricted when necessary. With the help of creating a network, devices like printers and scanners, files and data that are stored in the system can be shared.
In networking the communication language used by computer devices is called the protocol. Network implement multiple protocols for to support specific application.
