The links connect two or more nodes with each other. See More: Building a Disaster Preparedness Strategy? Here’s How Leading Service Providers Can Help Key Components of a Computer Networkįrom a broader lens, a computer network is built with two basic blocks: nodes or network devices and links. It is a combination of computer science, computer engineering, and telecommunication. Every time we connect via a video call, stream movies, share files, chat with instant messages, or just access something on the internet, a computer network is at work.Ĭomputer networking is the branch of computer science that deals with the ideation, architecture, creation, maintenance, and security of computer networks.

A simpler example is using collaboration software such as Google Drive to share documents with colleagues who work remotely. These systems alert officials and emergency responders with information about traffic flow and incidents. Organizations of all sizes use networks to connect their employees’ devices and shared resources such as printers.Īn example of a computer network at large is the traffic monitoring systems in urban cities. Today’s world revolves around the internet, which is a network of networks that connects billions of devices across the world.
We have come a long way today from that basic kind of network. Government researchers used to share information at a time when computers were large and difficult to move. The first working network, called ARPANET, was created in the late 1960s and was funded by the U.S. These devices are connected using physical wires such as fiber optics, but they can also be wireless. Computing devices include everything from a mobile phone to a server.
