Computer network (ing) is a process of sharing information plus revealed resources between two or more connected computers. The revealed resources may include printer, Fax modem, Hard drive, CD - DVD Rom, Database plus the data. A computer network is separated into a little or surrounding location network, a networking between computers in a building of the office (LAN), medium sized network (MAN), a network between 2 offices inside a city plus Wide network (WAN) a network amongst the computers, a person is nearby and also the additional could be thousands of miles away in almost any additional nation of the world.
WAN connectivity is attained by a network device well-known as "Router". The internet is the world's biggest WAN network, where countless of computers from all around the world and related to each additional.
Networking is the practice of linking 2 or more computers or devices with each other. The connectivity is wired or wi-fi. A computer network is classified in different techniques, depends found on the geographical area as stated above.
There are a couple of principal types of the pc network client-server and peer with peer. In the client host processing, a computer plays a main role well-known as host, where the files, data inside the form of webpage, docs or spread sheet data, movie, database & resources are placed.
All the other computers in the client/server network are called clients plus they receive the info from the server. In the peer to peer network all the computers play the same role with no computer work as a centralized server. In the main businesses around the world client-server network model is in major use.
A network topology defines the structure, design or design of the network. There are different topologies like bus, ring, star, relate, hybrid etc. The star topology is many popular network topology. In the star topology, all computers inside the network are related to a centralized device like hub or switch. Thus forms a star like structure. If the hubs/switch fails to function for any purpose then all connectivity plus communication between your computers of a network are stopped.
In the network, a well-known correspondence language can be used by the computers and the network devices plus this code is referred to as protocols. The most commonly used plus popular protocols on the internet plus at home plus other networks is named TCP/IP. TCP/IP is not a singleprotocol but it is a set of several protocols.
A network is a wired or wi-fi and TCP/IP protocol could work both in types of network.
A information flow inside a computer network may be separated into 7 logical levels called OSI layersmodel which was developed by Intel and Xerox Corporation plus 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 is divided into different scales and ranges plus it depends about the prerequisite of the network as well as the geographical area. Computer Network is split into Local Area Network, Personal Area Network, Campus Area Network, Wireless Local Area Network,Metropolitan Area Network plus Wide Area Network.
There are several network connection methods like HomePNA, Power line communication, Ethernet and Wifi connection system.A network will additionally be classified into several different kinds based about the providers it delivers like Server farms, Storage region networks, Value control networks, Value-Added networks,SOHO network, Wireless network plus Jungle networks.
