For the following questions, consider a paged memory system that has a physical main memory size of 32KB (215) and a page frame
dlinn [17]

Complete Question

For the following questions, consider a paged memory system that has a physical main memory size of 32KB (215) and a page frame size of 8KB (213). Consider a process P whose logical address space is 64KB (216). Important Note: If an answer requires an exponent, use the ^ character. For example: 216 would be entered as 2^16.

Question 1: How many physical page frames are there in the above paged memory system? ________(Your answer should be in exponential form)

How many bits are needed to represent a physical page frame number in the system? ____________

Question 2: How many logical pages are there for P? _____________(Your answer should be in exponential form. )

How many bits are needed to represent a logical page number for P? _____________

Answer:

1a) The number of physical page frames in the  paged memory system = 2⁵

1b) The number of bits that can be used to represent the physical page frame = 5 bits

2a) Number of logical pages = 2³

2b) Number of logical frame bits = 3 bits

Explanation:

Size of physical main memory = 32 kB = 2¹⁵

Space for Logical address = 64 KB = 2¹⁶

Page frame size = 8 KB = 2¹³

1a) The number of physical page frames in the  paged memory system

Number of page frames = physical main memory size / page frame size

 Number of page frames  = 2¹⁵ / 2¹³

Number of page frames = 2⁵

1b)The number of bits that can be used to represent the physical page frame

physical memory size = log2(2²⁰) = 20 bits.

Offset bits = log2(2¹⁵)  = 15 bits

Frame bits = physical memory size – offset bits

Frame bits = 20 – 15

Frame bits = 5 bits

2a)  Number of logical pages = logical address space / page frame size

Number of logical pages = 2¹⁶/2¹³

Number of logical pages = 2³

2b) Logical address space = log2(2¹⁶) = 16 bits

Offset bits = log2(2¹³)

Offset bits = 13 bits

Frame bits = logical address space bits – offset bits

Frame bits   = 16 – 13

Frame bits  = 3 bits

Using a while loop, create an algorithm extractDigits that prints the individual digits of a positive integer.
sergiy2304 [10]

Answer:

The algorithm is as follows

1. Start

2. Declare Integer N

3. Input N

4. While N > 0:

4.1    Print(N%10)

4.2   N = N/10

5. Stop

Explanation:

This line starts the algorithm

1. Start

This declares an integer variable

2. Declare Integer N

Here, the program gets user input N

3. Input N

The while iteration begins here and it is repeated as long as N is greater than 0

4. While N > 0:

This calculates and prints N modulus 10; Modulus of 10 gets the individual digit of the input number

4.1    Print(N%10)

This remove the printed digit

4.2   N = N/10

The algorithm ends here

5. Stop

<u>Bonus:</u>

The algorithm in Python is as follows:

<em>n = 102</em>

<em>while n>0:</em>

<em>     print(int(n%10))</em>

<em>     n= int(n/10)</em>

<em>    </em>

write the algorithm, flowchart and BASIC program to calculate the area of the rectangle length 50m and width 30m.​
GalinKa [24]

Answer:

The Basic Program is as follows:

10 LENGTH = 50

15 WIDTH = 30

20 AREA = WIDTH * LENGTH

25 PRINT AREA

30 END

The Algorithm is as follows:

1. Start

2. Let Length = 50

3. Let Width = 30

4. Compute Area = Length * Width

5. Display Area

6. Stop

See Attachment for flowchart (flowchart is designed using draw io tools)

Explanation:

The flowchart, algorithm and basic program all follow the same sequence and explanation

Using the basic program as a case study;

Line number 10: The program starts by initializing LENGTH to 50

Line number 15: It then initializes WIDTH to 30

Line number 20: The AREA is calculated by LENGTH * WIDTH

Line number 25: The value of AREA is printed afterwards

Line number 30: Lastly, the program stops execution
