Segmentation in Operating Systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a segment with a base address.

Operating Systems

segment_base = [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing base address with segment size or offset.

The base address of a segment is a fixed starting point in memory, often given as a number like 1024.

medium

Complete the code to check if an address is within the segment limit.

Operating Systems

if address < [1]:

Csegment_limit

Doffset

💡 Hint

Common Mistakes

Using base address instead of limit for boundary check.

The segment limit defines the maximum size or boundary of the segment. Checking if the address is less than the limit ensures it is inside the segment.

3fill in blank

hard

Fix the error in the code to calculate the physical address from base and offset.

Operating Systems

physical_address = segment_base [1] offset

Drag options to blanks, or click blank then click option'

B*

C-

D//

💡 Hint

Common Mistakes

Using subtraction or multiplication instead of addition.

The physical address is found by adding the offset to the segment base address.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps segment names to their sizes if size is less than 1000.

Operating Systems

{name: size for name, size in segments.items() if size [1] [2]

Drag options to blanks, or click blank then click option'

A<

B1000

C>

D500

💡 Hint

Common Mistakes

Using greater than instead of less than.

Using wrong number for comparison.

This comprehension filters segments with size less than 1000 and maps their names to sizes.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps segment names in uppercase to their sizes if size is greater than 500.

Operating Systems

{name[1]: [2] for name, size in segments.items() if size [3] 500}

Drag options to blanks, or click blank then click option'

A.upper()

Bsize

C>

Dname

💡 Hint

Common Mistakes

Not converting names to uppercase.

Using wrong comparison operator.

The comprehension converts segment names to uppercase, maps them to their sizes, and filters sizes greater than 500.
