All About Computer Networks

Over time, computers have become an indispensable part of a business. Computer installation, support and maintenance are services that all organizations require. As businesses grow, the number of computers in the organization also increases. It becomes imperative to establish a systematic way to connect these computers so that they run smoothly. Therefore, computers are interconnected in several ways. This is the concept of a computer network.

What is a computer network?

A computer network can be understood as a number of computers connected together to share resources. The most common shared resource is the Internet. Other resources can be printers, file servers, etc. Computers on the network can be connected via an Ethernet cable or wirelessly via radio waves.
Now we will see how the individual computers of a network are connected:
Computers connected in a network are called nodes.

Star topology:

In this case, there is a central node from which connections to individual computers are provided. In this case, even if there is a problem with a particular cable, the other computers can still operate without problems. On the other hand, this type of connection requires a lot of wiring.

Bus topology:

In this case, all computers are connected by a single cable. The information that goes to the last computer needs to travel through all the nodes. The main advantage is that it requires minimal wiring. However, if there is any failure in the cable, all computers will be affected.

Ring topology:

In this topology, all computers are connected via a single cable. The end nodes are also connected to each other. The signal circulates through the network to reach the desired recipient. In case a network node is configured incorrectly or there is some other problem, the signal will make numerous attempts to find the desired recipient.

Collapsed ring topology:

In this case, the central node is a network device known as a hub, router or switch. This device works in a ring with cable plugs. In addition, each computer is connected independently to the device via individual cables.

Each organization chooses its own network topology to ensure optimized operation of its computers. Once the computers are connected, the offices also have separate wiring closets, which is essentially a space containing a switching device that connects to the network.

There are a number of computer network companies that provide installation services, maintenance and support services that ensure the smooth and optimized operation of their systems.
