Duplex channel:

    It is a communicating channel that will allow the messages to flow both directions.
    It is a two-way communication channel.

Gateway

    It is a device, which will directs the message through the different network by different protocols.

Router

    It does not interface with the different protocols.
    It will detect the next node or point which will directs the message from the source to the destination.

Switch

    It allocates the traffic along the network path.
    If the congestion of the network is more then the protocols detects the less traffic path and transfer the network path to the other networks.

Network Topology

It is an arrangements of the computers over a network. Different kinds of topology are:

    Bus topology: it is a topology, which is connected to a single cable and forms a network. It is cheapest network topology.
    Ring topology: In this topology, the devices are connected to a single cable but the ends are connected to each other and forms a circle. The main advantages of this topology is that it can over to the larger distance compared to the other network topology.
    Star topology: There is a central device, which acts as a hub and is known as a star topology. It is mostly used in local area network.
