What is the Meaning & Definition of Network

A network or network consists of a set of computers connected to each other through various methods to share information and services. It is called network or also network to those series of computers or computing devices that are connected by cables, waves, signals or other mechanisms in order to transmit data among themselves, in addition to resources and services, in order to generate a shared work experience, and save time and money.
Computer networks may vary in their nature and characteristics, but very often respond to an interest of cooperative work in an office, company or another area that requires the collaborative effort of several involved. Currently, they are very common in businesses and institutions because they allow not only share information and implement joint actions, but also to save connection costs and software licenses.
Internet, for example, is a network, through which computers in the world are connected through a technology that allows them to Exchange content with web sites and other programs. An Intranet, on the contrary, is a private or internal network that, while it also uses Internet technology, is used inside a company or group.
Networks are classified according to their scope (personal, local, campus, metropolitan area or wide-area), by method of connection (guidance, which can be wired, fiber or similar, or not guided, which involves radio waves, infrared, laser or wireless), according to functional relationship (client to server) or peer equal or p2p, for its architecture (bus network (, Star, ring, mesh, tree or mixed), and by data direction (simplex, half duplex, full duplex).
In contemporary societies, ever more networks become essential for communication between individuals and corporations at all times, allowing as fast as simple exchanges, and facilitating cooperative work and strategic actions.The definitions are based on information published on line consulted on the website:
