Computer networking is really a procedure for discussing data and shared sources between several connected computers. The shared sources may include printer, Fax modem, Hard disk drive, CD – DVD Rom, Database and also the documents. A pc network could be split into a little or lan, a networking between computers inside a building of the office (LAN), medium-sized network (MAN), a network between two offices inside a city and Wide network (WAN) a network between your computers, the first is in your area and yet another could be a large number of miles away in almost any other country around the globe.
WAN connectivity is achieved with a network device referred to as “Router”. The internet may be the world’s largest WAN network, where countless computers from around the world and associated with one another.
Networking is the concept of linking several computers or devices with one another. The connectivity could be wired or wireless. A pc network could be categorized diversely, depends upon the geographical area as pointed out above.
There’s two primary kinds of the pc network client-server and peer to see. Within the client server computing, a pc plays a significant role referred to as server, in which the files, data by means of webpages, docs or worksheet files, video, database & sources are put.
The rest of the computers within the client/server network are known as clients plus they obtain the data in the server. Within the peer to see network all of the computers take part in the same role with no computer behave as a centralized server. Within the major companies all over the world client-server network model is within major use.
A network topology defines the dwelling, design or layout of the network. There are various topologies like bus, ring, star, mesh, hybrid etc. The star topology is most generally used network topology. Within the star topology, all of the computers within the network are of a centralized device for example hub or switch. Thus forms a star like structure. When the hubs/switch fails to get results for whatever reason then all of the connectivity and communication between your computers of the network is going to be stopped.
Within the network, a typical communication language can be used through the computers and also the network devices which language is called protocols. Probably the most generally used and popular protocols around the internet and in your home along with other systems is known as TCP/IP. TCP/IP isn’t a singleprotocol but it’s a collection of countless protocols.
A network could be a wired or wireless and TCP/IP protocol could work in kinds of network.
An information flow inside a network system could be split into seven logical layers known as OSI layersmodel which was produced by Apple and Xerox Corporation and it was standardized by ISO.
1. Application layer
2. Presentation layer
3. Session layer
4. Transport layer
5. Network layer
6. Data Link layer
a. Media access control sub-layer
b. Logical link control sub-layer
7. Physical layer.
A network could be split into different scales and ranges also it depends upon the advantages of the network and also the physical location. Network System could be split into Lan, Personal Area Network, Campus Area Network, Wireless Lan,Metropolitan Area Network and Wide Area Network.
There are many network connection methods like HomePNA, Power line communication, Ethernet and Wireless connection method.A network may also be categorized into a number of different types in line with the services it offers like Server farms, Storage space systems, Value control systems, Value-Added systems,SOHO network, Wireless network and Jungle systems.
