Ethernet Hub

A network hub or repeater hub is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single network segment. Hubs work at the physical layer (layer 1) of the OSI model. The device is thus a form of multiport repeater. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision.

Hubs also often come with a BNC and/or AUI connector to allow connection to legacy 10BASE2 or 10BASE5 network segments. The availability of low-priced network switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications. More on Wikipedia...

Network Switch

A network switch is a broad and imprecise marketing term for a computer networking device that connects network segments.

The term commonly refers to a 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 referred to as Layer 3 switches or Multilayer switches.

The term Network switch does not generally encompass unintelligent or passive network devices such as hubs and repeaters.

The first Ethernet switch was introduced by Kalpana in 1989. More on Wikipedia ...

Network Router

A router (pronounced /'rautər/ in the USA, pronounced /'ru:tər/ in the UK, or either pronunciation in Australia) is a computer whose software and hardware are usually tailored to the tasks of routing and forwarding information. More on Wikipedia ...
