what is networking

Computer networking enables devices and endpoints to be connected to each other on a local area network (LAN) or to a larger network, such as the internet or a private wide area network (WAN). This is an essential function for service providers, businesses and consumers worldwide to share resources, use or offer services, and communicate. Networking facilitates everything from telephone calls to text messaging to streaming video to the internet of things (IoT).

The level of skill required to operate a network directly correlates to the complexity of a given network. For example, a large enterprise may have thousands of nodes and rigorous security requirements, such as end-to-end encryption, requiring specialized network administrators to oversee the network.

At the other end of the spectrum, a layperson may set up and perform basic troubleshooting for a home Wi-Fi network with a short instruction manual. Both examples constitute computer networking.

What is Networking? Networking is the exchange of information and ideas among people with a common profession or special interest, usually in an informal social setting. Networking helps a professional keep up with current events in the field, and develops relationships that may boost future business or employment prospects. Needless to say, it also provides opportunities to help other people find jobs, make connections and catch up on the news.
