Networking
A network is a group of computers and other devices connected together. These connections can be with cables, wireless connections, or both.Many components and technologies are working together behind the scenes to ensure a networked computer can access resources on the network.
It also consists of a collection of computers,printers,scanner and other devices that are connected
together.
Networking has single purpose to share information as fast as possible.
Benefits of Networking
-file sharing:-
All types of data(Audio,Video,Text and image)can be easily shared and accessed on network.
-Resource sharing-
Resources like scanner,printers,network data and applications can be accessed by remote connection devices using network connected devices.Example, a application can be shared by multiple users.-Internet sharing:-
A single internet connection can be shared with multiple users and devices.-Increasing storage capacity:-
Access any types of media files stored remotely on other computers storage devices (Example NAS-Network Attached Storage)The basic types of network
Computer users use their computers for browsing the Internet, sending and retrieving email, scheduling meetings, sharing files, preparing reports, exchanging images, downloading music, and maybe checking the current price of an auction item on the Internet. All this requires computers to access multiple networks and share their resources. The multiple networks required to accomplish this are the local area network (LAN), the enterprise network, the campus area network (CAN), the metropolitan area network (MAN), Metro Ethernet, the personal area network (PAN), and the wide area network (WAN).
- LAN :- LAN stands for Local Area Network.It is used to network computers within a limited area like offices ,school by using the network media. The area covered upto 1 k.m no need a internet another name intranet.
- CAN:- Campus Area Network is an interconnected of local area network(LANs) within a limited geographical area. Campus network can be additional to the set of wireless connections,content several buildings to the same network,but it is not the same thing.A can is smaller than a wide area network.Example, corporate office campus, university etc. have interconnected administrative buildings.
- MAN:- Metropolitan Area Network which optimized for a larger geographic area than a LAN, ranging from several blocks of buildings to entire city.Two or more LAN connected with each other is called metropolitan area network is covered a whole city.Example cable network another name extranet.
- WAN:- Wide Area Network that is a network connection of wide area such as the world.Example -internet(covered whole city)
- PAN:-Personal Area Network which is referred to the interconnected of information technology devices mostly up to 10 meters.These interconnected devices might include laptop computers,mobile phones,printers or other computer device.It is also known as a wireless personal area network(WPAN).
