A network is a system or structure through which multiple devices are connected and can exchange information. In the modern era, a network usually refers to a computer network, where multiple computers, servers, mobile devices, and other network devices can communicate with each other. Devices can share information, files, software, and other resources through networks, making our daily tasks much easier. And so through today's post, we will know what is Network. what is the function of the network? And all network-related details. So let's get started.

What is a Network? What is the Function of the Network?

A network is a system in which various devices, such as computers, servers, mainframes, and other network devices are connected, facilitating the exchange of information and data between them. This attachment is made according to a specific structure, which is technology-based. As a result, it is possible to transmit information from one end of the world to the other instantly.

 

Thinking back to the past, people used different mediums to exchange information, such as letters, faxes, or face-to-face communication. At that time the transmission of information took a long time and was quite complicated in many cases. But modern networking technology has eliminated those complications. Now we can easily communicate anywhere in the world through the Internet.

Types and functions of networks 

Types of networks and their operations form the basis of modern technology systems. Different types of networks and their functions greatly impact our daily lives. Here are the three main network methods discussed in detail:

 

1. Local Area Network (LAN)

A local area network, or LAN for short, is a network that is limited to a specific small geographic area. For example, this could be a school, office, or network installed within a building. LANs typically operate over a limited area, where computers, servers, and other devices are connected and share information.

2. Metropolitan Area Network (MAN)

A metropolitan area network, or MAN, is a network that spans a specific city or metropolitan area. It consists of multiple LANs, spread over a large geographical area. A MAN can typically span 60 to 70 miles and forms a larger network by connecting multiple LANs.

3. Wide Area Network (WAN)

A wide area network, or WAN, is a network that spans a large geographic area. It can spread across different countries or continents, crossing the boundaries of a city or country. Through WAN we can easily exchange information from one end of the world to another.

 

Devices connected via a WAN communicate with each other using transoceanic cabling or satellite uplinks. This allows devices located in different parts of the world to be connected. WAN's data transfer rates typically range from 56 kbps to 1.544 Mbps, which is very effective for exchanging information over large geographic areas.

Network usage benefits

The benefits of using the network are unique. The technological development of the modern world has resulted in networks making our lives easier and more efficient. Some of the significant advantages of the network are discussed in detail below:

 

1. Send email quickly

One of the biggest advantages of the network is that you can send emails from anywhere in the world within seconds. Where it once took days or sometimes weeks to send a letter, it is now possible to exchange information in an instant via email. From business communications to personal messages, everything is now done easily and quickly through email.

 

2. Ease of data collection and use

Another great advantage of the network is that it allows you to collect and use different types of information. You can read newspapers, download pictures, and even collect video or audio files from anywhere in the world through the Internet. From education to entertainment, in every field, the network gives you access to a vast wealth of information, which enriches your life.

 

3. Advantages of cloud computing

You can take advantage of cloud computing through networking. Cloud computing is a method where you can access different software, storage, and processing power over the Internet. It allows you to securely store your data and files, which you can access from anywhere in the world. With cloud computing, there is no problem due to the limited capacity of your device, as all the processing work is done on the cloud server.

Disadvantages of Network

In addition to the advantages of the network, there are also some important disadvantages, which can cause major problems if we are not aware of them. As this advancement in technology has made our lives easier, if we don't know its proper use, we can face various dangers. Here is a detailed discussion of some of the significant disadvantages of using networks:

 

• Trafficking of personal information

•  Hacking the data of banks and big organizations

•  Computer virus attack

•  Social and psychological effects

The disadvantages of using a network should not be overlooked either. We can avoid these problems through proper and safe use of technology. To enjoy the benefits of the network we need to be aware and take necessary security measures.
