Benefits of computer networks

A computer network is a computer network of two or more computers.

Or a printer, camera, phone, server, or database, any other device that needs to be connected to other devices to exchange data between them.

Computer networks can be classified according to the method of interconnection between devices. There are three main types of networks: wired networks, that is, networks that are connected by wired connections or copper wires or optical fibers. It may be a wireless network (English: wireless) that supports radio wave communication between networks, as well as advanced networks, which are satellite networks, through which devices are connected to each other through satellite signals sent to the earth, which is the most accurate Internet, the fastest on the ground.

Types of computer networks There are many types of networks, because each type has a specific purpose and a specific standard, and geographic area is one of the most important factors controlling the type of network to be used, and the type of network in the computer world is: Local Area Network : The network where the equipment is located in one place or one building.

personal area network: This is a person's personal network, which contains different devices that a person works on, such as computers, phones, and printers, and is usually located in the domain of the owner. The form of computer network The form of computer network differs according to its purpose of use, and the form depends on the distribution of equipment, the method and direction of data transmission, the dependence of network equipment on the main server that organizes the data transmission between them, and the form of computer network Varies.
