A process needs 103 KB of memory in order to run. If the system on which it is to run uses paging with 2 KB pages, how many frames in memory are needed

Answers

Answer 1

Answer: 52

Explanation:

Following the information given in the question, we are informed that a process needs 103 KB of memory in order to run and that the system on which it is to run uses paging with 2KB pages, then the number of frames in memory that are needed will be:

= 103/2

= 51.5

= 52 approximately

Therefore, 52 frames in memory are needed.

Connie works for a medium-sized manufacturing firm. She keeps the operating systems up-to-date, ensures that memory and disk storage are available, and oversees the physical environment of the computer. Connie is employed as a __________. Hardware Engineer Computer Operator Database Administrator Computer Engineer

Answers

Answer: Computer operator

Explanation:

Following the information given, we can deduce that Connie is employed as a computer operator. A computer operator is a role in IT whereby the person involved oversees how the computer systems are run and also ensures that the computers and the machines are running properly.

Since Connie keeps the operating systems up-to-date, ensures that memory and disk storage are available, and oversees the physical environment of the computer, then she performs the role of a computer operator.

Write a program that will read two floating point numbers (the first read into a variable called first and the second read into a variable called second) and then calls the function swap with the actual parameters first and second. The swap function having formal parameters number1 and number2 should swap the value of the two variables.
Sample Run:
Enter the first number
Then hit enter
80
Enter the second number
Then hit enter
70
You input the numbers as 80 and 70.
After swapping, the first number has the value of 70 which was the value of the
second number
The second number has the value of 80 which was the value of the first number

Answers

Answer:

The program in Python is as follows:

def swap(number1,number2):

   number1,number2 = number2,number1

   return number1, number2

   

first = int(input("First: "))

second = int(input("Second: "))

print("You input the numbers as ",first,"and",second)

first,second= swap(first,second)

print("After swapping\nFirst: ",first,"\nSecond:",second)

Explanation:

This defines the function

def swap(number1,number2):

This swaps the numbers

   number1,number2 = number2,number1

This returns the swapped numbers

   return number1, number2

The main begins here

This gets input for first    

first = int(input("First: "))

This gets input for second

second = int(input("Second: "))

Print the number before swapping

print("You input the numbers as ",first,"and",second)

This swaps the numbers

first,second= swap(first,second)

This prints the numbers after swapping

print("After swapping\nFirst: ",first,"\nSecond:",second)

Explanation:

From the question, we can see that Roland is familiar with both machines and software. He is familiar with the operations of both parts of a computer to the end that he can attempt a fix. And if he can't he knows who to refer the end-users to. Usually, some IT personnel that is more experienced.

From the above points, we can safely say that Roland is an IT Support Analyst. He cannot be the Systems analyst because Systems Analysts are usually at the top of the Pyramid. They take on problems that are referred upwards to them from support analysts.

The correct call to installApplication

The function installApplication is declared as void, meaning that it is not expected to return anything.

Also, it receives a character and an integer argument.

So, the call to this function must include a character and an integer argument, in that order.

Option D is incorrect because both arguments are integer

Option C is incorrect because it passes no argument to the function.

Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).

Answers

Answer:

The output is:

Explanation:

Given

See attachment for code segment

Required

The output of rec2(5)

From the attached code segment, we have the following:

The base case: if (x==0){ return;}

The above implies that, the recursion ends when the value of x gets reduced to 0

The recursion:

rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function

printf("%d ", x); This prints the passed value of x

Hence, the output of rec2(5) is: 1 2 3 4 5
