Computer Networking

Computer networking is a process of sharing information and resources shared by two or more computers. Shared resources can include printer, fax modems, hard drives, CD - DVD Rom, databases and data files. A computer network can be divided into a small network or local network between computers in an office building (LAN), network support companies (MAN), a network between two offices in a geographic area network ( WAN), a network between the computer and the other is at the local level can be thousands of miles away in any other country world.WAN connectivity is achieved by a network device known as a "router". The Internet is the biggest WAN in the world, where millions of computers from around the world and linked other.Networking is the practice of linking two or more computers or devices together. Connectivity can be wired or wireless. A computer network can be classified in different ways, depending on the geographical area mentioned above.There are two main types of computer network client-server and peer to peer. In client-server, a computer plays an important role known as the server, the files, the data in the form of web pages, files or spread sheet docs, videos, databases and other resources are placed.All computer client / server network are called clients and get the data from the server. In peer to peer network all computers have the same role and act as a centralized computer system without server.

[ABSTRACT] Computer networking is a process of sharing information and resources shared by two or more computers. Shared resources include printers, fax modems, hard drives, CD-DVD-ROM, databases and data files. A computer network may be in a small area or local network, a network between computers in a building with an office (LAN), media network (MAN), a network between two offices in a city and Wide Area Network (WAN) a network is divided between a local computer and the other thousands of miles away could be the connectivity world.WAN in any other country by a network device such as "router" are achieved. The Internet is the biggest WAN in the world where millions of computers around the world and connected other.Networking is the practice of linking two or more computers or devices together. The compound may be wired or wireless. A computer network can be classified in different ways, depending on geographic area as mentioned above.There are two main types of computer network client-server and peer to peer. In client-server, a computer plays an important role as a server where the files, the data in the form of Web pages, documents, spreadsheet files, videos, databases and other computer resources placed.All client / server network is known to be called customers and receive data from the server. Playing in the peer-to-peer network, all computers have the same role, acting not as a central server. In large companies around the world, client-server network in major use.A network topology, structure, design or layout defined in a network. There are several topologies, such as bus, ring, star, mesh, hybrid, etc. The star topology is the most commonly used network topology. In a star topology, all computers on the network with a central device such as a hub or switch connected. Thus forming a star like structure. If the hub / switch fails, then for some reason, all the connectivity and communication between networked computers are halted.In operate the network, a common communication language that is used by computers and network devices, and this language is known as Logs. The most common protocols and popular Internet and other networks at home and is called TCP / IP. TCP / IP is not a single protocol, but it is a collection of different protocols.A wired or wireless network, and TCP / IP, both types of network.A flow of data in a computer network to work can be, can be divided into seven logical layers are called OSI layered model that was developed by Intel and Xerox Corporation, and was standardized by ISO.1.

A computer network can be divided into local networks, personal networks, campus area, networks, wireless local area networks, metropolitan area network and network-wide Network.There connection area are several methods, such as HomePNA, Power line communication, Ethernet and Wi-Fi mode. A network can also be various ways to provide services, such as server farms, storage networks, control networks of value, value added networks SOHO Networking, Networking and Wireless networks are categorized based jungle.
