Computer networks connect a variety of devices and computers to each with the ability to share information and resources. This enables businesses to communicate more efficiently and enhance productivity. They also offer better service to their customers. A computer network is made up of two fundamental components: nodes or devices and links. Nodes are communication devices, such as computers, printers as well as mobile devices, while links are the physical connections that transport data between them. These connections include cables, fiber optics and wireless signals such as Wi-Fi. Data is transmitted from one point to another with a set pre-programmed protocols, also known as communication protocols.

Computer networking has many benefits.

Computer networks are the most effective when they permit users to share hardware and software resources. A network permits multiple employees to share the same printers or scanners. This lowers costs and boosts productivity since every employee does not have to have their own equipment. It also facilitates the sharing of documents in a simple manner, which can make processes easier in areas such as project collaboration and recording. Additionally, the use of computer networks allows organizations to manage and monitor huge amounts of data. This can be beneficial to industries like banking, insurance and marketing.
