What is Networking and How does it Work?

A computer network (networking) is a collection of interconnected computers that may exchange and pool resources and data. Computers and other gadgets may now work together to make communication easier for their users.

To put it simply, a computer network is a group of connected computers. Both wired and wireless media can be used to set up a network connection. Computers and other devices in any network require both hardware and software to function.

There are several types of nodes that make up a computer network. Nodes in a network might be anything from dedicated servers to personal PCs to networking devices. They may be recognized by their hostnames and IP addresses.

What is Networking?

Professional networking, in contrast to computer networking, is the practice of establishing and keeping professional contacts within one’s specialty. It’s a crucial part of progressing in one’s profession and may help one learn more and meet more people.

Attending industry events, engaging in online forums, joining professional organizations, and seeking out mentoring or coaching are all examples of professional networking. It’s possible to network by reaching out to folks via email, LinkedIn, or some other means of communication.

Informal encounters, such as chit-chatting with coworkers during breaks, exchanging resources, and working together on projects all count as forms of networking.

How Does a Computer Network Work?

Using nodes and connections, computer networks are able to function. Nodes are any pieces of data communication hardware. Links in computer networks are the connections between nodes and may take the form of intermediary devices like modems, hubs, switches, and so on. Links come in many forms, including cable lines, optical fibers, and more. 

Nodes in a computer network are responsible for data transmission and reception whenever the network is online. Protocols provided by a computer network make it easier to adhere to established norms and procedures.

Applications of Computer Networking

The following are examples of how computer networking may be used:

  • One of the most useful functions of computer networking is the sharing of resources. Multiple people can access the same program at the same time. This method can also be used to facilitate the sharing of hardware devices.
  • In this context, “Communication Medium” refers to the many channels we might use to exchange information and ideas with one another.
  • The use of computers and networks in the home is becoming increasingly crucial. User-to-user communication, entertainment, electronic commerce, etc. are all good examples.
  • The business world is another significant user of computer networking. With the aid of Computer Networking, nearly all businesses now conduct at least some of their operations online.
  • One of the most popular and cutting-edge uses of computer networking nowadays is social media. It’s useful for learning about the latest events, trends, and other information of various kinds.
  • Networked computers allow users to have access to data stored at faraway locations. Information needed for rail or aircraft tickets is one example. 
  • Cloud computing is a service made possible by networked computers that enable users to access and store their data and programs on remote servers over the internet.
  • Networking tech also paves the way for virtualization, which boosts efficiency by allowing several virtual computers to share a single physical system.
  • Distance learning, online courses, and virtual lecture halls are just a few examples of how advancements in computer networking have changed the face of education.
  • Workers may now do their jobs from anywhere, not just the workplace, thanks to advancements in networking technology. During the current COVID-19 outbreak, this is more crucial than ever.
  • Networked computers have aided the expansion of e-commerce by making it possible for companies to sell their wares to customers all over the world.
  • Networking technology has also made possible telemedicine, which allows doctors to consult with and diagnose patients located in far-flung areas through video calls.
  • Networking technologies allow for real-time collaboration, meaning that individuals from different locations may work together on projects and communicate information in near-real time.

Advantages of Computer Networking

Connectivity and information sharing are greatly facilitated by networking. In addition to that, there are a plethora of additional benefits. Some of the most notable ones are listed below:

Convenience of access

Explore a network with little effort using today’s technology. As a result, anyone, from a child to a person unfamiliar with technology, will have no trouble establishing a connection. 


Here, adaptability indicates that many individuals can probe various avenues of inquiry depending on their own needs. For this reason, the internet offers a plethora of options for disseminating data. Like email or WhatsApp, which is a messaging app. Therefore, it’s adaptable to a wide range of users.

Ease of pooling resources

A computer network’s primary function is to facilitate resource sharing among its users. Multiple users can make use of the same set of resources, such as printers, scanners, and photocopiers. Large corporations benefit greatly from pooling their resources in this way, as they can communicate with their staff via a single, unified network. 


Networked computers make it easier for people to stay in touch no matter where they are. Real-world examples abound in the form of video chat programs and the usage of Google Docs to stay in touch with loved ones and coworkers through these trying times. 


Authorization systems implemented in computer networks ensure safety. User identification and passwords are used for authentication. So, it makes sure that we can only log in if our information exactly matches what’s already in the database. 

Capacity for storing

Data storage needs to be prioritized by businesses. They must keep them on a centralized server for this reason. A centralized server is a server located off-site that all workers may connect to. Therefore, even if some of the data is lost, others still have it. 

Cost Savings

When weighing the benefits and drawbacks of a technological option, cost is often at the top of the list of considerations. By storing all of an organization’s files on a single server, networking helps businesses save money.

Disadvantages of Computer Networking

  • The “central server” is the primary server in a network of computers. The whole network would be rendered inoperable in the event of a problem with or a failure of the central server. The reliance on a single server is a significant drawback.
  • Because of the linked nature of computers in a network, it is likely that the virus will spread from infected computer to infected computer. The system as a whole may be harmed by this propagation. Furthermore, as the network is dependent on the central server, its corruption poses a significant threat.
  • There is no autonomy in the network because it relies on a single server. This means that users cannot conduct their own preferences in how they employ the computer.
  • The various benefits and uses of a network inevitably lead to users being exposed to several, potentially distracting services at once. Thus, problems with productivity are widespread since workers tend to multitask. 
  • Entertainment in the form of games, films, and other media may be accessed through a computer network. This causes you to rely too much on these services since you can’t get enough of the addictive material. You’ll feel tired and have headaches and bodily aches from staring at screens for too long.


In conclusion, networking is a fundamental concept that underpins the modern interconnected world. It involves the establishment of connections and communication pathways between various devices, systems, or individuals, enabling the seamless exchange of information, resources, and services. Networking operates through a combination of hardware and software components, including routers, switches, protocols, and addressing schemes.
