Router Manufacturers

A router is a computer-networking device, which buffers and forwards data packets across an internetwork toward their destinations, through a process known as routing. Routing occurs at layer three of the OSI seven-layer protocol stack. It act as a junction between two or more networks to buffer and transfer data packets among them. A router is different from a switch and a hub: a router is working on layer three of OSI model, a switch on layer two and a hub on layer one. This makes them work for different situations: a switch connects devices to form a Local area network.
