Networking Cable, Connetors and Ports

A network cable is a type of telecommunications wiring that transmits data from individual computers to a large network.

Networking Tools and Accessories

A crimp tool is a device used to join two pieces of metal together by twisting one or both pieces to hold the other. An example of crimping is affixing a connector to the end of a cable.

Network Interface Card

It is a circuit board installed in a computer that provides a dedicated network connection to the computer. It is also called network interface controller, network adapter.

Basic Networking Devices

Simply a multi-port repeater. Used to connect multiple devices to the same network drop.

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.

Bridges are a way of segmenting traffic between the two Ethernet segments.

A repeater is a network device used to regenerate analog or digital signals that are distorted by transmission loss due to attenuation

Transmitter and Receiver of electronic signals—specialized repeater. Connects different media technologies.

Routing and Switching Devices

A layer 2 switch is a type of network switch or device that works on the data link layer (ISO OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded.

A network device that forwards traffic based on layer 3 (OSI Model) information at very high speeds.

A ROUTER is a connection device that transmits packets of data between various computer networks.

A Gateway is a network node that forms a passage between two networks operating with different transmission protocols. The most common type of gateways, the network gateway operates at layer 3, i.e. network layer of the OSI (open systems interconnection) model.

Wireless Networking Devices

Nework Security Devices

A Firewall is a network security device, either hardware or software-based, which monitors all incoming and outgoing traffic and based on a defined set of security rules it accepts, rejects or drops that specific traffic.

A Jammer is a mobile communications device that transmits on the same frequency range as a cellphone to create strong cell tower interference and block cellphone signals and call transmission.
