When the computer first came out... it was the only device of its kind. Its widespread use later paved the way for the development of hardware and software... through which multiple computers could communicate with each other. Computer communication refers to the process... Through which data, instructions and information from one computer reaches another computer. In the beginning only large computers had the ability to communicate... but today even small computers and devices can communicate with each other.

Computer Network

Networked computers and devices are such... which is associated with a communication channel. Through this user can share data, information, hardware and software with other users. Personal or network computers are connected to a network for several reasons. It has the ability to share data, information, hardware and software and facilitate communication.

Networking Requirements

To share hardware: Every computer on the same network can access and use the hardware. For example, assume that a network consists of several computers and each computer needs a laser printer. In such a scenario, each computer connected to the network can use only one laser printer.

To share data and information: While working on any computer included in the same network, any legitimate user can access the data and information collected on any other computer and use it. For example, a database of computer information may be saved on a server's hard disk. Any legitimate user on the network...even mobile users on handheld computers can access and use this database. Access to storage data and information is a very important feature of many networks.

To share software: In software sharing, the most used software is stored on the server's hard disk... so that several users on the network can access it simultaneously. When you buy the network version of a software package... Then the software vendor asks you for a legal agreement... called a site license. It allows several users to use the software package simultaneously. Site license fees are typically based on the number of computers or users on the network. Network sharing costs almost nothing compared to buying software for each computer separately.

Facilitated communication networks allow people to communicate with each other in an effective and simple manner through e-mail, instant messages, chat rooms, telephony and video conferencing. E-mail messages are usually delivered instantly. Sometimes this communication is also useful in a business network.

There is a whole range of network sizes. A small network connects two computers to each other... On the other hand, like a global network, millions of computers in the world are connected to each other in the Internet. Networks connect all types of computers together be it handheld computers or supercomputers!.

Type of Computer Network

Networks are mainly of three types – LAN, MAN, WAN which are used by individuals, business houses and various organizations. Since every business and organization has its own requirements... each network has its own specialty. The size of the network depends on what kind of network the business house or organization wants to use. Networks of different sizes transmit data in different ways.

For example, a peer-to-peer network with 1,000 users is heterogeneous and requires a diversity of hosts... which is not the case in a network with only five users.

Local Area Network (LAN)

A computer network in a building or multiple buildings... In which two or more computers are physically connected to each other... it is called local area network. The connected computers are called workstations. In this, computers are interconnected so that expensive equipment, such as laser printers, can be used in a connected manner, databases and applications stored on servers can be accessed by all workstations. Local area networks have their own characteristic topologies, such as boss, ring, or star, and implement multiple networking protocols simultaneously, such as AMPL, Talk, Ethernet, or TCP/IP.

Metropolitan Area Network (MAN)

It is a high speed network Which can transfer voice, data and images at a speed of up to 200 Mbps (megabytes / per second) at a speed of 75 km. The distance can reach a few blocks of buildings or an entire city. Transmission speed depends on the network architecture and can be higher for shorter distances. mANs consist of one or more LANs... even telecommunications equipment, such as relay stations. It is smaller than a wide area network... but its speed is usually higher. Microwave and satellite.

Wide Area Network (WAN)

A WAN is a computer network... that differs greatly from a local area network because of its ability to communicate over long distances. This network can cover the entire country and all sites of large multinational companies. WAN is used to connect different local area networks and other networks together... so that a user sitting in one place can communicate with another user sitting far away through his computer. Most WANs are created by organizations and are private. The rest is made by the Internet Service Provider and any other network is connected to the Internet through a LAN connection. Communication is usually provided by one or more national or international government units.
