Wireless router - freedom of movement
Today it is very difficult to find a person whoDo not use a computer, tablet, smartphone or other such devices. The technology of processing information flows has long ceased to be something unknown and incomprehensible.
A router is a special device,which is used to combine various disparate information flows and to specify routes for their further follow-up. A wireless router is a device with exactly the same functionality, but has the additional ability to connect other designs via wireless data transmission technologies. Roughly speaking, the simplest device of this type takes a data packet, "understands" where it should be sent, writes an additional address and sends it to the next node (usually also a router).
Modern wireless routers, in addition to routing functions, also perform the function of protecting information from various external threats and attacks.
An ordinary wireless home routerlooks like a small box. Connect it to the power adapter and one or more antennas designed to amplify the wireless signal. Also, an access point to the global network is attached to it. And it can be both wired (twisted pair, less often - optical patchcord), and wireless.
Individual models can provide the ability to connect to a printer router that will act as a network device in a public format for authorized users.
