Laptop Networking

Pc networking is a process of sharing data and shared resources between two or additional connected computers. The shared resources will embrace printer, Fax modem, Laborious disk, CD - DVD Rom, Database and the data files. A computer network will be divided into a small or native area network, a networking between computers in a very building of a workplace (LAN), medium sized network (MAN), a network between 2 offices in an exceedingly town and Wide network (WAN) a network between the computers, one is domestically and the opposite will be thousands of miles away in any alternative country of the world.

WAN connectivity is achieved by a network device referred to as "Router". The web is the world's largest WAN network, where lots of computers from all over the world and connected with each other.

Networking is the observe of linking two or a lot of computers or devices with every other. The connectivity can be wired or wireless. A computer network can be categorized in different ways in which, depends on the geographical area as mentioned above.

There are 2 main varieties of the computer network client-server and peer to peer. Within the consumer server computing, a laptop plays a major role referred to as server, where the files, data in the shape of net pages, docs or unfold sheet files, video, database & resources are placed.

All the other computers in the shopper/server network are referred to as shoppers and that they get the info from the server. In the peer to look network all the computers play the same role and no pc act as a centralized server. In the key businesses around the world client-server network model is in major use.

A network topology defines the structure, style or layout of a network. There are totally different topologies like bus, ring, star, mesh, hybrid etc. The star topology is most typically used network topology. In the star topology, all the computers within the network are connected with a centralized device such as hub or switch. Therefore forms a star like structure. If the hubs/switch fails to figure for any reason then all the connectivity and communication between the computers of a network will be halted.

Within the network, a common communication language is employed by the computers and the network devices and this language is known as protocols. The most commonly used and in style protocols on the net and in the house and other networks is called TCP/IP. TCP/IP is not a singleprotocol but it's a set of many protocols.

A network can be a wired or wireless and TCP/IP protocol can work both in sorts of network.

A knowledge flow in an exceedingly pc network will be divided into seven logical layers known as OSI layersmodel that was developed by Intel and Xerox Corporation and was standardized by ISO.

1. Application layer

2. Presentation layer

3. Session layer

4. Transport layer

5. Network layer

6. Knowledge Link layer

a. Media access control sub-layer

b. Logical link management sub-layer

7. Physical layer.

A network will be divided into completely different scales and ranges and it depends on the need of the network and therefore the geographical location. Pc Network can be divided into Native Area Network, Personal Space Network, Campus Area Network, Wireless Local Space Network,Metropolitan Space Network and Wide Area Network.

There are many network association methods like HomePNA, Power line communication, Ethernet and Wifi affiliation method.A network can conjointly be categorized into several completely different types primarily based on the services it provides like Server farms, Storage area networks, Price management networks, Price-Added networks,SOHO network, Wireless network and Jungle networks.
