Answer:

Category 3 (CAT3) Unshielded Twisted Pair cable

Explanation:

A Category 3 (CAT3) Unshielded Twisted Pair cable is a cable that makes use of the conductivity of copper to transmit data and power. These cables are an older standard for Ethernet cables and can handle data speeds of up to 10mbps.The succeeding standard for Ethernet cables include CAT5 which has speeds of up to 100 mbps, CAT 3 is mostly used in applications where speed is not of great importance such as in PBXs and VoIP telephone systems.

Kipish [7]

Answer:

Option d) B is 1.33 times faster than A

Given:

Clock time, t_{A} = 100 ps

t_{A} = 150 ps

No. of cycles per instructions,  n_{A} = 2.0

n_{B} = 1.0

Solution:

Let I be the no. of instructions for the program.

CPU clock cycle, f_{A} = 2.0 I

CPU clock cycle, f_{B} = 1.0 I

Now,

CPU time for each can be calculated as:

CPU time, T = CPU clock cycle\times clock time

T_{A} = f_{A}\times t_{A} = 2.0 I\times 100 = 200 I ps

T_{B} = f_{B}\times t_{B} = 1.0 I\times 100 = 150 I ps

Thus B is faster than A

Now,

\frac{Performance of A}{Performance of B} = \frac{T_{A}}{T_{B}}

\frac{Performance of A}{Performance of B} = \frac{200}{150}

Performance of B is 1.33 times that of A
