Computer networks connect a variety of devices and computers to one other, allowing them to share resources and information. This enables companies to communicate more effectively and improve productivity. It also allows them to offer better customer service. A computer network is composed of two primary components, nodes or devices and links. Nodes are endpoints for communication, like printers, computers and mobile devices, and links are the physical connections that carry data between them. These links comprise cables, fiber optics and wireless signals such as Wi-Fi. Data is transmitted from one point to another with a set pre-programmed rules known as communication protocols.
Computer networking can bring many benefits.
The most obvious benefit of computer networks is their ability to share software and hardware resources. For example, a network could allow several employees to use the same printers and scanners. This helps to cut costs and boost productivity by allowing work to be completed without the need for each employee to have their own equipment. It also allows for easy sharing of documents which can streamline processes in areas such as project collaboration and recording. Computer networks can make it easier for businesses to manage and control large volumes of data. This is beneficial for businesses such as banking, insurance and marketing.
