All about computer networks
Over a period of time, computers have become an indispensable part of the business. Computer hardware installation, support and maintenance are services required by all organizations. As a business grows, the number of computers in an organization also increases. It becomes necessary to establish a systematic way to connect these computers so that they work in a trouble-free manner. Therefore, computers are interconnected in different 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 popular resource is the Internet. Other resources can be printers, file servers, etc. Computers in a network may be connected through an Ethernet cable or wirelessly through radio waves.
Now we will see how the individual computers in the network are connected:
Computers connected in a network are referred to as nodes.
star topology:
In this case, there is a central node through which communications are provided to individual computers. In this case, even if there is any problem with a particular cable, other computers can continue to work without hindrance. On the flip side, this type of connection requires a lot of cables.
Bus topology:
In this case, all computers are connected with one cable. Information intended for the last computer must travel through all nodes. The main benefit is that it requires minimal cabling. However, if there is any cable failure, all computers will be affected.
Loop topology:
In this structure, all computers are connected through a single cable. The final nodes are also connected to each other. The signal propagates through the network to reach its intended recipient. If a network node is configured incorrectly or there is some other problem, the signal will make several attempts to find its intended recipient.
Collapsed Loop Topology:
In this case, the central node is a network device known as a hub, router, or switch. This device runs in a loop containing additional cable components. Each computer is connected independently to the machine through individual cables.
Each organization chooses its own computer network architecture to ensure the functioning of its computers. Once the computers are connected, the desks also have separate cabling cabinets, which is basically a space that holds a switch that connects to the network.
There are a number of computer networking companies that offer installation, maintenance and support services to ensure the smooth and streamlined functioning of your systems.
