Computer networks are the foundation of communication in the IT industry (information technology). These networks use multiple types of networks in different ways. A computer network can be created by linking many machines together to exchange information. These networks have been used to connect computers in the past and have various topologies. The most common topology at the present is a collapsed ring since this form of protocol supports the internet, LANs, and WANs.

Information sharing is one of the many tasks carried out via computer networks. Users can share equipment like scanners and printers, connect via email, instant messaging, and video, exchange files and software, and access and manage information with ease thanks to the advantages offered by this network. This article provides a general overview of a bridge in a computer network.
What is computer networking?
A network of connected computers that can communicate and share resources is known as a computer network. These networked devices use a set of rules called communications protocols to transmit data through wireless or physical technologies.
How does a computer network work?
Nodes and connections are the basic building blocks of computer networking. A network node could be data communication equipment (DCE), which comprises a modem, hub, or switch, or data terminal equipment (DTE), which contains two or more computers and printers. A link is the communication medium used to connect two nodes. Links can be physically present, such as cable wires or optical fibres, or they might be empty areas that wireless networks use.
Nodes in a working computer network adhere to the rules or protocols that outline how to transmit and receive electronic data over the links. The computer network architecture dictates the designs of these logical and physical components. It provides the standards for the network's operating structure, physical components, protocols, and practises.

What do computer networks do?
The earliest computer networks were created in the late 1950s for use in defence and military applications. They were initially employed to transmit data over telephone lines and had a small number of commercial and scientific applications. Computer networks are now crucial for organisations thanks to the advancement of internet technology.
Modern network systems give more than just connectivity. They are crucial to the operation of contemporary businesses and the digital transformation of several sectors. There are now more programmable, automated, and secure components in place for networks.
Functions of computer network
Data about sales and transactions at the sale terminals can be introduced through WANs. A computer may also centralise this data for processing or broadcasting purposes. For example, supermarkets linked by WANs in different cities can broadcast all sales information from their remote selling centres. tya. a jert......, .ty
Centralizing Information
It will be beneficial for a business to centralise local information. For instance, auto-parts sellers can help in discovering unique vehicle parts by using a centralised computer list of inventory items. Due to WANs, these dealers can search centralised databases.
Facilitating Communications
Businesses in industrialised countries utilise WANs to enhance staff communications, reduce the expense of long-distance calls and long-distance writing, organise written records more cheaply, and avoid the time-consuming nature of conventional means of information transfer between branches.

Exchange messages
This device transmits messages quickly. Through online platforms like Facebook, Whatsapp, and Skype, we can interact with a partner.
High bandwidth
The dedicated connections give significant bandwidth if our organisation employs them. The high bandwidth makes information transit more expensive, which boosts the effectiveness of our company.
Wrap Up
With the aid of a good understanding of network technology, you can design and construct a secure network for your company. You must keep a close eye on what is going on around your network equipment if you want to make sure that every component of the system is performing at its peak.
Quickly detecting errors and fixing issues is an essential part of managing a network. Along with the other criteria, strong security is essential for preventing unauthorised access.
