The Importance of Computer Networks in Business

Computer networks connect computers and other devices together to exchange information, resources and services. They can be based on wireless or wired connections and are able to be configured in various network topologies. Networks are essential for business in the present and allow us to communicate with colleagues, collaborate and work more effectively. They also assist with data security and accessibility.

Computer networking is a broad field that covers the creation, maintenance, and architecture of communication networks. It is a mix of electrical and computer science. engineering.

The most famous computer network is the Internet which allows billions of people to connect and utilize the same resources simultaneously. The network employs a packet-switching model to guide data through an almost infinite number of pathways and connections. Each packet contains both information about control and information from the user. The control information contains source and destination network addresses as well as error detection codes and sequencing information. The data portion of a packet contains the payload.

In a typical network central servers store data and manages access by users to vital resources like printers, photocopiers, and files. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users have access to access the network. The fact that all information is centralized on servers also helps administrators to perform regular backups of their data and enforce strict security guidelines for the network. It also allows employees to access corporate services and apps regardless of where they are located — such as video-calling software and document-sharing.
