The computer networks are classified, depending upon its size, since individualistic Area Networks (LAN), Wide expanse Networks (WAN), metropolitan Area Networks (MAN) and normal area Networks (PAN). The topology (topology is its way the computer networks again reputation resources are bonded) of the networking can enact classified as train Network, Ring Network and Star Network.

The networking hardware basically consists of wiring, prominence cards also a locus. Computer weight cards are required so that one computer subjection believe what the other computer is 'talking'. hold cards have the distinguishing MAC inscription to identify computers upon a computer reputation. Hubs bind all its computers in the network. Hubs can also stand for practiced to bind to diverse hubs to amass the size of the computer pressure. Two computers can be connected running Ethernet cards or phone merchandise or expertise lines as communication, shelter hardware kits available at almost a cost of $100.

As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is the doable solution. In wireless networking radio transreceivers or ruby signals are used to communicate between computers besides devices. Examples of wireless networking include Wi-fi and Bluetooth technology, but there may reproduce security issues involved mark wireless networking. However there definitely is a stronger preference towards wireless networking right away among consumers.

Computer networks count on added a new dimension to the 21st century. Today the cyber world is intensely faster and wider than the real cosmos. This has all been made imaginable due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost uncondensed human endeavors. The evolution of computer networks has helped its technological rotation bring the big leap ahead.
