what is networks ? How are they useful?
Answers
A network allows sharing of network and computing resources. Users may access and use resources provided by devices on the network, such as printing a document on a shared network printer or use of a shared storage device.
Network is any technology by which two or more computer systems are connected and communicate information between them. This can be as simple as a dial-up modem connection between two PCs, or as complex as the Internet itself. Whether it’s a wired local area connection at work, a home WiFi connection, an undersea cable connecting devices beneath the ocean, or satellite signals all around the globe, all of these are network technology.
From a more human standpoint, though, network technology is any technology by which people communicate with one another, and reach out to each other. Our computer networks only exist because of our human need to network with one another. Humanity is at the heart of all of our communication. Never forget that.
