What Is One Function Of A Router?
A router is basically a device that is designed to direct the flow of information between networked computers. The router evolved from earlier devices like hubs and switches, but it was enhanced to perform operational tasks that the earlier devices were not capable of. A router can recognize incoming information and, using tables and contrasting planes, it can quickly and efficiently direct the data to the appropriate locations. Sophisticated routers have the capability to "learn" to some degree, which allows them to gradually increase their effectiveness in a network environment.
