What is the Need of Computer Network?

In the modern era, computers have become a vital component of both commercial and private operations in the industry sector. As technological developments have accelerated, networking has become increasingly important. We have gradually transitioned from the first wired network technology to wireless networking technology. If we look at it now, we can see that networking affects everything.

A computer network is a collection of interrelated devices that can share resources and exchange data with one another. A network's devices can be physically connected with wires or wirelessly with the help of radio waves or infrared signals. These devices employ a set of regulations and rules called protocols that help to transmit data over physical wire or wireless technologies.

The main motivation for a computer network is to enable devices to communicate with one another and share resources, including files, information, apps, and hardware components such as printers and scanners. E-mail, virtual teamwork, sharing files, video conferencing, playing games online, and accessing the internet are all potential uses for computer networks. Computer networks are now a crucial part of any business communication system.

If you know how a computer network works, it's easy for you to understand why a computer network is needed. Here, we provide simple information about how a computer network works.

How Does a Computer Network Work?

Here's a quick rundown of how a computer network works −

  • Devices are linked − Devices are physically linked via wires or wirelessly via Wi-Fi or other wireless technology.

  • IP addresses are assigned to devices − Each network device is assigned a unique IP address, enabling it to be recognized on a network.

  • Data transfer − When equipment sends data across a network, it is broken down into small fragments called packets, which are then delivered to the final destination device.

  • Routing − Data packets are routed via a network using different pieces of equipment known as switches, routers, and hubs, which guide the data packets to their final destination.

  • Shared resources − Users can more easily access resources like printers, data, and internet access because equipment on a network can collaborate on these things.

In general, a computer network is an intricate framework that involves numerous devices cooperating to offer interaction and communication.

Need of Computer Network

Computer networks have become vital in the modern age because they allow interaction as well as sharing of resources among various devices and individuals. The following is a list of things that we do via computer networks, matters that we benefit from using computer networks, or items that have become achievable or in effect as a result of computer networks. Let us know all the details so that we can understand the significance of computer networking.

  • Easy resource sharing − Computer networks allow users and devices to share resources like printers, documents, and apps easily. This increases efficiency while decreasing the expense of offering resources.

  • Good communication facility − Computer networks help individuals to communicate with one another regardless of where they are. Individuals can communicate in real-time using networking tools such as instant messaging, email, and video conferencing.

  • Access information − Networks enable access to a diverse set of services and information, such as the internet, database servers, and cloud-based services for computing. Individuals can now obtain and share data all over the globe.

  • High security − Networks enable the deployment of security precautions like encrypted connections, firewalls, and access control that help protect sensitive information and data from illicit access and other safety hazards.

  • Collaboration − Networks enable collaboration among people and groups engaged in the same task, regardless of their geographical location. This encourages collaboration, improves productivity, and fosters creativity.

  • Centralized management − Networks enable centralized handling of resources, apps, and information.


Finally, computer networks serve as vital for today's interaction, teamwork, and information exchange. Computer networks play an important role in the modern digital age, from sharing resources to interaction, and transfer of data to scalability and safety. Progressively becoming more dependent on technological advances, the need of computer networks will only increase.
