Router is a device of limitless potential and exceptional functions that enabled it to become one of the most popular network accessories. The greatest power of a router is universality which is one of the most valued of the functions of a router. One router at home or in an office is most cases enough to provide stable Internet connection. The amount of computers connected not stated but it is reasonable to keep in mind that the more computers use network at the same time, the slower the connection is. As computers maintain a connection within their own exclusive network they in fact share information. In high-tech terms we could say that routers shift data.
When there is only LAN (Local Area Network) computers located in one place, usually at school or in the office shift data among each other while in the case of WLAN (Wireless Local Area Network) the connection and shift of data can be observed on a high-scale. High-scale information share is worldwide and there are basically no other limits than the possible lack of Internet connection.
The functions of a router enable this small box-resembling device to create networks of a great scope where computers can interact with each other with no wires between computers included. Interaction between computers through Wireless LAN is so spectacular that information processing takes only a fraction of seconds. Routers are responsible for information exchange that begins its journey leaving a particular computer. Then, information undertakes a journey through many different networks and eventually, it returns to the source. All in a matter of seconds.
One of the most popular devices are Cisco routers. They are used in most of best companies.
