Computer networks connect a variety of devices and computers with each other, allowing them to share resources and data. This lets businesses communicate more effectively, improve productivity, and provide better customer service. A computer network consists of two fundamental components: nodes or devices, and links. Nodes are devices used for communication, like mobile devices, computers, and printers, while links are physical connections that transmit data between them. These links include cables, fiber optics and wireless signals such as Wi-Fi. Data is transferred from one node to another with a set pre-programmed rules called communication protocols.
Some of the main advantages of computer networking are:
The primary benefit of computers is the ability to share hardware and software resources. A network allows multiple employees to share the same printers or scanners. This lowers costs and boosts productivity because each employee does not need to own their own equipment. It facilitates document sharing, which can streamline processes such as project collaboration and record-keeping. Furthermore, the use of computer networks makes it easier for companies to manage and control large amounts of data. This can be advantageous for industries such as marketing, banking, and insurance.
