    VI. Procedure (Knowledge)

    Different networking devices have different roles to play in a computer


    network. These network devices also work at different segments of a
    computer network performing different works. In our new series after
    network types and classifications, we discuss about different
    networking devices like a switch, router, hub, bridge etc.

    Hubs

    Hubs enable computers on a network to communicate. Each computer


    plugs into the hub with an Ethernet cable, and information sent from
    one computer to another passes through the hub.

    A hub can't identify the source or intended destination of the


    information it receives, so it sends the information to all of the
    computers connected to it, including the one that sent it. A hub can
    send or receive information, but it can't do both at the same time.

    3
    Switch

    Switches work the same way as hubs, but they can identify the intended
    destination of the information that they receive, so they send that
    information to only the computers that are supposed to receive it.
    Switches can send and receive information at the same time, so they
    can send information faster than hubs can.

    networking-devices/

    Bridge

    A bridge is a computer networking device that builds the connection


    with the other bridge networks which use the same protocol. It works
    at the Data Link layer of the OSI Model and connects the different
    networks together and develops communication between them. It
    connects two local- area networks; two physical LANs into larger logical
    LAN or two segments of the same LAN that use the same protocol.

    Router

    Routers enable computers to communicate and they can pass


    information between two networks— such as between your home
    network and the Internet.

    Wireless Access Point (AP or WAP)

    Access points (also called base stations) provide wireless access to a


    wired Ethernet network. An access point plugs into a hub, switch, or
    wired router and sends out wireless signals. This enables computers
    and devices to connect to a wired network wirelessly.

    Patch Panel

    A panel that allows multiple devices to be connected and managed in a


    more efficient manner. Computer networks, sound studios, television
    stations, and a number of other systems use patch panels to deal with
    components of their electronic systems.

    Modem (Modulator-Demodulator) – The modem is a device that allows


    a given computer to share data or otherwise a device which let
    computers exchange information.

    6
    Network Operating System (OS)

    A network operating system (NOS) is an operating system that manages


    network resources: essentially, an operating system that includes
    special functions for connecting computers and devices into a local area
    network (LAN). Example of NOS: Windows Server, Windows Server 2008
    R2.

    Modular Box

    It is a surface mounted box used in a commercial and industrial


    building to cleanly attach network cables. It is commonly used in a
    structured network.

    Network Cable Tester or LAN Tester

    A cable tester is a device that is used to test the strength and


    connectivity of a particular type of cable.

    Punch Down Tool

    A punch down tool, also called a krone tool, is a hand tool used to
    connect telecommunications and network wires to a patch panel,
    punch down block, keystone module, or surface mount box.

    Crimping Tool and Wire Stripper

    A crimping tool is a device used to conjoin two pieces of metal by


    deforming one or both of them in a way that causes them to hold each
    other. A tool designed to remove the protective covering (jacket) off of a
    cable to expose the inner wires.

    Latest models of crimping tool come with wire strippers already.
