Computer networking is a broad area that includes the conception the design, structure, and maintenance of communication networks. It is a combination of computer science, electrical engineering, and telecommunications.

The Internet is the most well-known computer network with billions of users to connect and share the same resources at the same time. The network employs a packet-switching model to guide data through an almost endless number of possible routes and connections. Each packet contains information about control and data from the user. The control information contains the source and destination network address, error detection codes, and sequencing information. The payload is located in the data portion of a byte.

In a typical business network there is a central server which stores data and manages user access to vital resources such as photocopiers, printers and files. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users can access the network. The centralization of information on servers makes it easier for administrators and security policy enforcers to carry out regular backups. It also lets employees access corporate services and apps, regardless of where they are located including video-calling software as well as document-sharing.
