Brian gathers data from his classmates about the computers they own such as the type of operating system, the amount of memory,

Stells [14]

Incomplete question. The Options read;

A. The year purchased

B. Brian's classmates

C. The amount of memory

D. The type of operating system

Answer:

B. Brian's classmates

Explanation:

Remember, the question is concerned about "the individuals" in the data set, so the year they purchased their computer, neither is the amount of memory of the computer and the type of operating system can be classified as individuals in the data set.

Hence, we can correctly say, only Brian's classmates are the individuals in this data set.

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times

otez555 [7]

Answer:

The program written in python is as follows

def countchr(phrase, char):

count = 0

for i in range(len(phrase)):

if phrase[i] == char:

count = count + 1

return count

phrase = input("Enter a Phrase: ")

char = input("Enter a character: ")

print("Occurence: ",countchr(phrase,char))

Explanation:

To answer this question, I made use of function

This line defines function countchr

def countchr(phrase, char):

This line initializes count to 0

count = 0

This line iterates through each character of input phrase

for i in range(len(phrase)):

This line checks if current character equals input character

if phrase[i] == char:

The count variable is incremented, if the above condition is true

count = count + 1

The total number of occurrence is returned using this line

return count

The main method starts here; This line prompts user for phrase

phrase = input("Enter a Phrase: ")

This line prompts user for a character

char = input("Enter a character: ")

This line prints the number of occurrence of the input charcater in the input phrase

print("Occurence: ",countchr(phrase,char))

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.
