A computer system has 9,850 processes and 172 of them were suspended while 276 of them were terminated. Explain why some of the
Mrrafil [7]

Answer:

Check below for answers and explanations.

Explanation:

The major reasons why computer processes are suspended or terminated are:

1. When there is insufficient memory for successful completion of the process

2. When there's an unauthorized access of any of the computer resources by the process.

It is possible that some processes are terminated why some are suspended because, when the system runs out of memory, the running processes are put on hold until the system is able to create free memory space for the completion of the process. In this case the process is suspended. But if the system cannot provide enough space for the process, the process is terminated.

In the example provided in this exercise, some of the processes were suspended because the system wants to create free memory space for their completion while others are terminated either because the available space is not sufficient for their completion or they want to access an unauthorized resources on the system.

   count1 = count2 = 0

   while True:

       choice = input("Enter a letter / digit to stop: ")

           break

       elif choice.isalpha():

           count1 += 1

           if choice in vowels:

               count2 += 1

   print("You entered " + str(count1) + " letters, " + str(count2) + " of which weere vowels.")

   print("The percentage of vowels was " + str(count2 / count1 * 100) + "%")

LetterGame()

Explanation:

Create a function called LetterGame

Inside the function:

Create a list of vowels

Initialize count1, counts the total letters, and count2, counts the vowels

Initialize a while loop that iterates until the specified condition is met in the loop

Get the input from the user. If it is a digit, stop the loop. If it is an alphabet, increase the count1 by 1, and also check if it is a vowel. If it is a vowel, increment the count2 by 1

When the loop is done, print the required information

Finally, call the function
