    Bridges :

    - Bridges are used to extend networks by maintaining signals and traffic.

    - It connects multiple device segments.

    Routers :

    - Routers are used to connect different LANs or a LAN with a WAN (eg. the Internet).

    - It receives a signal and retransmits it at a higher level.

    - If a packet destination is on a different network, a router is used to pass it the right way, so without router the Internet would not perform.

    Gateway :

    - A gateway may contain devices such as protocol translators, signal translators etc.

    - Gateway is called as a protocol converter that can operate in any network layer.

    - It provides translation services between incompatible LANs.

    - A gateway is an essential feature of most routers.

    - A protocol translation or mapping gateway interconnects networks with different network protocol technologies by performing the required protocol conversion.

    Repeaters :

    - Repeater is an electronic device that receives a signal and retransmits it at a higher level or other side of an obstruction, so that the signal can cover longer distances.

    - It receives a signal and retransmits it at a higher level.

    - It is a generic term that refers to several different types of devices such as a telephone repeater.
