Networks
The phrase networks describes two or more computer systems or electronics devices that are linked together. Network connections enable networked computers and devices to communicate with each other and share files, folders, data and more. Networks are essential to enterprise operation and have become increasingly common in the home as well.
From networking protocols and standards to network routing, security and management, our networks dictionary offers a glossary of key terms you need to know.
