Network hardware.
Switches are one of the four main types of what?
Network hardware.
Hubs are one of the four main types of what?
Network hardware.
Network Interface Cards are one of the four main types of what?

Define a router.
A router directs packets of data to their destination on the network. It also acts as a gateway between different protocols and to shared resources like an Internet connection.
What directs packets of data to their destination on the network?
A router.
Define a switch.
A switch is a sophisticated piece of equipment that segments traffic onto smaller networks. It is design to improve the efficiency of network transmission.
What is a sophisticated piece of equipment that segments traffic onto smaller networks?
A switch.
Define a hub.
A hub simply re-broadcasts traffic on each of its ports. It extends the network, but can cause congestion as it is not a managed device and has no awareness of data layers.
What re-broadcasts traffic on each of its ports?
A hub.
Define a Network Interface Card (NIC).
The NIC converts data from the form in which it is stored into a form that allows it to be transmitted over a network.
