What is network Definition and examples

What is network and its types

Friends, are you searching for what is network – (What is Network) and type of network – (Types of Network). So you have chosen a well-informed article. Friends, when the computer first appeared, it was a tool in itself.

But later its widespread use opened the way to create systems like hardware and software so that computers could be communicated through this.

Computer communication refers to the process through which data, instructions and information can be transmitted from one computer to another computer. Initially only large computers had the ability to communicate

But now even the smallest computers and devices can communicate with each other and all this has been successful only through networking. Let us know what is called a network and why was the need for networking.

What is Network

A network is a group of computers and devices that are connected through a communication channel. Through this, a user can share data, information, hardware and software to other users. In other words the definition of network can be something like.

Definition of network → When one or more computers are interconnected and exchange information through some medium, then the medium through which information is exchanged. it’s called a network

Friends, personal and institutional computers are connected in a network for various reasons. It has the ability to share data, information, hardware and software and establish communication.

Types of Network

Friends, let me tell you for your information that there are mainly three types of networks. Which is Local Area Network (LAN), Metropolitan Area Network (MAN), Wide Area Network (WAN)

Local Area Network (LAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)

Networks are generally used by private, business houses, organizations. Because every business and organization has its own unique needs, every network is unique in itself.

Local Area Network – LAN

A network in a building or group of buildings in which two or more computers are physically connected to each other. Known as Local Area Network (LAN)

Connected computers are popularly known as workstations. In this, computers are connected to each other so that expensive equipment such as laser printers can be used jointly. The databases and applications in the server are accessible from all workstations.

Local area networks have their own topologies such as bus rings, stars and they simultaneously implement more networking protocols such as Apple, Ethernet or TCP/IP.

Metropolitan Area Network – MAN

A metropolitan area network is a high speed network. Which can share data up to 200 Mbps. It can be moved rapidly over a distance of 75 kms in a few blocks of buildings or across the city.

The transmission speed is based on the architecture of the network and can be high for short distances. Which includes one or more LANs even telecommunication equipment such as microwave and satellite relay stations. A metropolitan area network is smaller than a wide area network. But its speed is usually higher.

Wide Area Network – WAN

A wide area network is a computer network. Which is a local area network due to its ability to communicate over long distances.

The metropolitan area is quite different from the network. Under this network, the whole country and all the sites of a large multinational company can be covered.

Wide area network is used to connect local area network and other networks together. So that a user sitting at one place can easily communicate with another user located at a distance.

Most wide area networks are maintained by a specific organization and are private. They are also made by other Internet service providers and by giving a connection to an organization, it is connected to the Internet.

Friends, let me tell you for your information that communication is usually provided by one or more national and international government units.

Networking required

Friends, the need for networking came to the fore in view of the following facts in the computer.

• to share hardware
• To share data and information
• software to share
• to facilitated communication

To share hardware

Every computer in a network can access and use the hardware. For example, suppose there are many computers connected to a network and each computer needs a laser printer. In this case, the same laser printer can be used by every computer connected to the network.

To share data and information

Any legitimate user can access and use data and information stored on any other computer while working on any computer included in a network. For example – database of computer information can be saved in the hard disk of the server.

Any legitimate user on the network, even a mobile user using a help hand computer, can access and use the database. The ability to access and use storage data and information is a very important feature of many networks.

Software to share

In software sharing, the most commonly used software is stored on the hard disk of the server so that many users involved in the network can access and use them simultaneously.

When you buy a network version of a software package, the software vendor provides you with a legal agreement. Which is called a site license. This allows multiple users to use the software package at the same time.

Site license fees are usually determined by the number of computers or users on the network. The cost of network sharing is almost negligible compared to purchasing software for each computer separately.

To facilitated communication

The network can be used to communicate effectively and easily through email, messaging, chat rooms, telephone and video conferencing. Email messages are usually instant delivery. Sometimes it also acts as a communication business network.

Friends, let me tell you for your information. The network range is of one size. A small network connects two computers, while in a global network like the Internet, millions of computers in the world are connected to each other and exchange information. Networks can interconnect everything from handheld computers to supercomputers.

What is network hardware

Friends, let me tell you for your information that network hardware is the equipment that is included in the network. All networks require network hardware to function. The following are examples of network hardware –

• Required Tools for Networking
• computer
• network interface card
• connector
• cables
• resource

1- Computer → The most important function of the network is to connect the computers together. When computers are connected, people can use them to work more effectively, that’s why computers come under networking hardware.

2- Network Interface Card → An expansion card or other device that provides network access to computers and other devices such as printers. Known as Network Expansion Card. Plays a role between computers and physical media such as cables through which transmission is possible.

3- Connector → Connector is a device that works to connect two networks together. The most common connector is Hub and Router.

4- Cables → You must have seen a group of wires or glass wire, all these are called cables. Using cables is also essential for networking. Through this, the work of data sharing is done. This is an extremely important networking hardware.

5- Resource → Any part of the computer system or network such as disk drive, printer or memory that can be allocated to a program. they are called resources.
