Which type of cabling below is the most common type for recent Ethernet installations?

A.
Twinax

B.
Twisted Pair

C.
ThickNet

D.
ThinNet

Explanation:
Category 5 Unshielded Twisted Pair (UTP) is rated for very high data throughput (100 Mbps) at
short distances (up to 100 meters), and is the standard cable type for Ethernet installations.
* ThickNet, also known as 10Base5, uses traditional thick coaxial (coax) cable at data rates of up
to 10 Mbps.
* ThinNet, uses a thinner gauge coax, and is known as 10Base2. It has a shorter maximum
segment distance than ThickNet, but is less expensive to install (also known as CheaperNet).
* Twinax, is like ThinNet, but has two conductors, and was used in IBM Systems 36 and earlier
AS/400 installations.
