How Does a Computer Network Work

The first computer network was installed by ARPA (Advanced Research Projects Agency), known as the ARPANET at the end of 1960. A computer network is a network of several computers using certain network components. There are many types of networks, classified by geographical location devices and network components. Connect the connection type to computers and network components used, select the type of network. Let's understand how a computer network.
Network components in the computer network


types of work and computer networks Let's take a brief account of how a computer network, according to the classification of types of computer network.
Geographical Location LAN (Local Area Network) A computer LAN are interconnected, and other resources such as printers, modems, floppy disks and hard drives. LAN is a building or confined in the office, or maybe a network access equipment and residential resources with each other. With the help of the computer network on the LAN, the above resources are accessed and shared by all computers on the network. The team, which provides and manages the resources of a server computer is designated.
MAN (Metropolitan Area Network Metropolitan Area Network covers a diameter ranging from 5 to 50 km. The man is not heard by a single organization, but many LANs. Metropolitan Area Network has many applications and many networks, such as banking network, military network, the network of dealers and flight booking network can. These networks need a lease line taken by the phone company. Speed ​​data line varies from 2 Mbps to 600 Mbps MAN Some networks support the Internet Protocol (IP) and as a network service provider (NSP). The network service provider is the backbone of the Internet Service Provider (ISP) to connect to all ISPs. In general, the Internet is retrieved by an Internet service provider.
WAN (Wide Area Network) Wide Area Network connecting all metropolitan networks (MAN). Wide Area Network is a larger version of the local area network (LAN). Internet is an example of WAN.
GAN (Global Area Network) The global network consists of all wireless LANs and satellite communications. The example of the Global Area Network Broadband Global Area Network (BGAN), which connects to all voice and broadband wireless data communications on Earth.
connection types Computer Network LAN twisted pair cable, coaxial cable and fiber optics, used to connect computers and other network components together. twisted pair telephone cable used to connect computers. Coaxial cables are the cable television network cable to connect to the Internet, and switch the computer network. In the technology of fiber optics, voice and data services such as light is transmitted.
PC Wireless Network The wireless computer network using wireless technologies such as satellite communications, wireless LAN and Bluetooth. The satellite uses microwaves, data and information on the network. Wireless LAN requires a router and network adapter. To learn more about how the wireless LAN, you can refer to "How does a wireless network.
These are the types of computer networks and the answer to your question of how a computer network. The computer network is used depends on the size and type of network connection.• The network interface card (NIC) • Axles • Bridges • Repeater • Switches The network elements used to connect computers to be interconnected:
