Term
1. What does a PC require to be able to communicate to a network?
Definition
Same Protocol



Explanation: Protocols are the rules for communicating on a network. Remember, all computers that wish to communicate must follow the same set of rules.
Term
2. An improperly configured network interface card could:
Definition
Prohibit Network Connection

Definition
Plug N Play


Explanation: If the PCI slot is fully Plug and Play (PnP), and if the card is also PNP, Windows is able to automatically recognize and configure it.
Term
Unshielded Twisted Pair (UTP) type cable uses which connectors?
Definition
RJ-45

Explanation: UTP uses the 8-pin RJ-45 connector.
Term
What is the maximum length of twisted-pair cable between devices?
Definition
328 FT and/or 100m
Term
When running network cabling, it's important to avoid placing the cables next to heavy machinery, printers, and heating units. This is to avoid which of the following?
Definition
EMI

Explanation: Running cables next to heavy equipment can cause Electromagnetic Interference (EMI). For example, putting speakers next to a monitor may cause the sound output to be scratchy. This is an example of EMI. If you move the speakers, the sound will be reproduced correctly. No permanent damage has resulted. The same is true if you run a data cable too close to an EMI source. Data flow may be interrupted. Remove the EMI, and your network should function properly.
