A. Networking cables are used to connect one network device to other network devices or to connect two or more computers to share a printer, scanners etc.
B. Shielded twisted pair relies solely on the cancellation effect produced by the twisted-wire pairs that limits signal degradation caused by electromagnetic interface (EMI) and radio frequency interference (RFI
C. Categories of UTP are based on the number of wires in the cable and the number of twists in those wires
D. UTP cables have a range of 328 feet (100 m).

The sole purpose of the modem is to provide you with internet access. If you were to only have one internet-connected device with an Ethernet port (such as a desktop computer), you could connect the modem directly to your computer with no need for a router.

2. C. WAN

(Because)

WAN (Wide Area Network) is another important computer network that which is spread across a large geographical area. WAN network system could be a connection of a LAN which connects with other LAN's using telephone lines and radio waves.

3. B. Shielded twisted pair relies solely on the cancellation effect produced by the twisted-wire pairs that limits signal degradation caused by electromagnetic interface (EMI) and radio frequency interference (RFI)

(Because)

It is supposed to be unshielded...Unshielded twisted pair (UTP) is the cable that has two or four pairs of wires. This type of cable relies solely on the cancellation effect produced by the twisted-wire pairs that limits signal degradation caused by electromagnetic interface (EMI) and radio frequency interference (RFI). UTP is the most commonly used cabling in networks. UTP cables have a range of 328 feet (100 m).

4. D.Virtual Private Network

(Because)

A VPN is a private network that uses a public network (usually the internet) to connect remote sites or users together. The VPN uses "virtual" connections routed through the internet from the business's private network or a third-party VPN service to the remote site or person.

5. B.Thinnet (10BASE2)

(Because)

Thinnet (10BASE2) is a coaxial cable used in networks operating at 10 Mbps, with a maximum length of 185 meters.
