As computer technology progresses, the distinction between router and switch products is becoming fuzzier. Essentially, routers are Layer 3 devices that connect different networks. A common example is connecting an office Ethernet network to the Internet via DSL. Switches are instead Layer 2 (L2) devices that interconnect various devices that share the same network. Basically, routers depend on CPUs to steer data based on sophisticated algorithms, offering flexibility at the cost of throughput. Switches, on the other hand, depend on largely predefined hardware designs to forward traffic at the fastest possible speed. Today's routers typically incorporate Layer 2 switching capability, and many of today’s switches include L3 routing capability. Routers offered by Cisco, the producer of 90% of the industry's routers, have improved significantly in function and speed and Cisco now offers an extensive portfolio that includes routers built to handle the requirements of customers ranging from households to nationwide service providers.
