Routers keep traffic not meant for a segment off of that segment and routers do not forward broadcast traffic. Thus, routers minimize collisions and broadcast traffic. Routers are best used on large networks using routable protocols such as TCP/IP and IP/!P. Routers should not be used to increase network performance on relati ely small networks and/or networks using nonroutable protocols such as #et$%&I.
