Answer:
(a)The CPU B should be selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.
(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A
.
Explanation:
Solution
(a)With regards to the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.
The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.
(b) The execution can be computed as follows:
Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time
Thus
CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)
CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second
Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A
Answer:
The above code print the text at three times.
Explanation:
- It is because the above code has one loop which executes three times. The loop executes for the value of i = 0,1 and 10.
- when the value of i is 0 then "++i" will increase the value 1 and the text will be printed.
- If the value of i=1, then the value of i is 2 in the second iteration and the again the text is printed, then the if condition gives the true result and the value of i will be 10.
- Then the loop executes for the last time when the value of i is 10.Then the value will be 11 because of the increment operator and the text will be printed for the third time.
- Then the while loop is not true for the 11 value of i and the loop will get terminated.
That is incorrect. It is only contagious if blood is injected into person who is not infected.
