Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time, 

No. of cycles per instructions, 

Solution:
Let I be the no. of instructions for the program.
CPU clock cycle,
= 2.0 I
CPU clock cycle,
= 1.0 I
Now,
CPU time for each can be calculated as:
CPU time, T = 


Thus B is faster than A
Now,


Performance of B is 1.33 times that of A
Answer:
The name of the components of the given labelled circuit is:
The box like figure in the given image is the battery source from where the current drawn into the circuit.
A string connecting positive terminal of battery to the bulb is an electric wire through which current flows in the circuit.
A bubble like object in the circuit is a bulb which lights up when current moves through the circuit.
A component connected to the negative terminal of batter source is a switch.
Then open circuit is an open as the key of the switch is open.
