Question 6

The wire that is twisted together protects against EMI ( Electromagnetic Interference)

Answer 6

UTP (Unshielded Twisted Pairs) Cables

Question 7

UTP Cables that has 2 pairs (4 wires)

Answer 7

• 10BASE-T
• 100BASE-T

Question 8

UTP Cables that has 4 pairs (8 wires)

Answer 8

• 1000BASE-T
• 10GBASE-T

Question 10

both devices send data at the same time, and no problems like collisions will occur since they use separate wires to transmit and receive data

Answer 10

Full-duplex transmission

Question 11

allows devices to automatically detect which pins their neighbor is transmitting data on and then adjust which pins they use to transmit and receive data.

Answer 11

Auto MDI-X

Question 12

used on switches that don’t support fiber optic connections to allow such connections

Answer 12

SFP (Small Form-Factor Pluggable) Transciever

Question 13

This type of cable allows longer cables that UTP but shorter than single mode.

Answer 13

Multi Mode Fiber

Question 14

Light enters at a single angle from a laser based transciever

Answer 14

Single Mode Fiber
