Computer network is a group of computers linked together for the purpose of communication. Networks that can be classified according to a variety of real estate. This article provides an overview of some of the types and categories, and provides the main components of the network.
WIRE AND WIRELESS NETWORK
Wireless data networks exist, such number and variety, which are difficult to classify, and compare. Some of the wireless communication network operating in the wireless voice networks, such as mobile telephony. CPDP, HSCSD, PDC-P, and GPRS are examples. Other wireless networks operate in the physical layer of networks using something handlheld antennas embedded devices for large antennas towers. 802.11, LMDS and MMDS examples. There are only few wireless networks for connecting small devices over short distances. Bluetooth is one example.
Wireless networks operate with other wireless networks, which often use the lower layer network to provide security and encryption. Autonomous wireless networks or provide their own security and encryption features, or is based (VPN for Virtual Private Networks) to provide these features. In many cases, several levels of security and encryption, it may be desirable.
Some wireless networks are stable, which means that the antenna does not move frequently. Other wireless mobile networks, which means that the antenna can move continuously. Sometimes it is the function and application design of an antenna, not the inherent limitations of standard wireless network.
Wireless networks may operate in licensed or unlicensed spectrum.
Types are classified in a number of systems or equipment which is connected to the region. Computer networks are one of the main wings of the computers.
Networking is the process by which two or more computers connected together is a perfect side. By creating a network of devices such as printers and scanners, software, documents and data stored in the system can be divided. It helps to communicate with the computer more easily. From the user's network access can be restricted if necessary.
