Computer Networks and benefits

Computer Networks and benefits

The computer network is a system that consists of computers and other devices that are designed to work together in various benefits and purposes , among others, to communicate , access information , receive and provide services . Section called Client receiving services and parts that provide a service called Server . This system is known as a client - server system that has been used in almost all computer network applications .

Understanding of computer networks

Computer network is a system that consists of a combination of computing devices that are designed to be able to share resources , communicate and access information from a variety of places between one computer to another computer .

The benefits of computer networks

Sharing of resources / data exchangeEasing communicating / transactingHelps access to informationAble to provide quick access to information and up - to-date

The types of computer networks based on the range

The LAN ( Local Area Network )

Local Area Network often encountered in office , campus , or cafe . This network can connect more than two computers in the room close range ( limited ) to some KM only. These networks typically consist of computers , printers , and other devices .

MAN ( Metropolitan Area Network )

True to its name the type of network provides services to a wide area and the ability of very high -speed data transfer . The area can be up to 50 KM range scope . MAN LAN is a series that is sized and larger.

WAN ( Wide Area Network )

This network type of service more broadly than the MAN that can connect a region even other countries . WAN is basically a collection of some of the existing LAN s across multiple locations so it takes a device to connect and the devices that we call the router .

The types of computer networks by function

The Client - Server
Is a computer network that is dedicated as a client and a server , these services can be provided by one or more computers .


Peer - to- Peer
Is a computer network that each of its host can be a server or a client simultaneously .

The types of computer networks based on topology

• Topology Bus
• Topology Ring
• Topology Tree
• Mesh Topology
• Topology Linear

The types of computer networks based on transmission media

Wired network ( Wired Network )

These networks using cable media in connecting each computer in the network

Wireless Network ( Wireless Network )

This network does not use the media as a means of connecting wires , but using electromagnetic waves in each shipment information signal .
