The Benefits of Computer Networks

Computer networks facilitate sharing and centralized management of information, resources and applications across multiple devices in a scalable, secure manner. Computer networks are an integral component of our modern world and provide numerous benefits, including improved communication and collaboration as well as lower costs, improved security and access to data and resources.

Networks are constructed from two essential elements, nodes and links. Nodes are devices that are networked, such as printers, computers and file servers. They communicate with each other using a set of rules known as communication protocol. Links connect these network nodes via wired or optical connections. A laptop that communicates with local networks via Wi-Fi can be described as a node (DTE) and the link (DCE). Routers and switches are traffic police that direct data packets in the most efficient way to their destination.

A wide-area network (WAN) makes use of bridges and gateways to connect various local area networks. A WAN unlike a local area network (LAN), is connected to global communication networks as well as the Internet. For instance, students from Florida can teleconference with peers in Tokyo at their workstations due to a WAN and bridge that connects them.

Computer networks aid in streamlining processes and help create a more active and collaborative work environment. For example employees can save files to an online server that is regularly backed up on a daily basis, rather than emailing documents back and forth, which could result in the loss of files. They can also access standard versions of employee or manuals for customers via the network. This ensures accuracy and consistency.
