Network switch
Switches exist for various types of networks including Fibre Channel, Asynchronous Transfer Mode, InfiniBand, Ethernet and others. The first Ethernet switch was introduced by Kalpana in 1990.[1]A network switch or switching hub is a computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches.Switches exist for various types of networks including Fibre Channel, Asynchronous Transfer Mode, InfiniBand, Ethernet and others.

A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or Jump to: navigation, search
A Cisco ASM/2-32EM router deployed at CERN in 1987
routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet.
A data packet is typically forwarded from one router to another through
the networks that constitute the internetwork until it reaches its
destination node.[1]
