Computer networks allow multiple computers and devices to communicate with each other and share information and resources. This enables companies to communicate more effectively and improve productivity. It also allows them to offer better service to their customers. A computer network is made up of two fundamental components: nodes www.boardroomco.net/how-to-type-on-a-pdf or devices, and links. Nodes are communication devices like mobile devices, computers and printers, and links are physical connections that transfer data between them. They include fiber optics, cables and wireless signals such as Wi-Fi. Data is transmitted from one node (or device) to another via pre-programmed communication protocols.

Computer networking offers many benefits.

Computer networks are the most effective when they allow users to share hardware and software resources. For instance, a computer network can allow many employees to access the same printers and scanners. This reduces expenses and increases productivity by allowing work to be completed without the requirement for each employee to own their own personal equipment. It allows for easy document sharing, which could simplify processes like project collaboration and recording. Computer networks can make it easier for businesses to manage and control large amounts of data. This is advantageous for industries such as marketing, banking, insurance and banking.
