Operating System » Memory Management Segmentation
In segmentation, each address is specified by ____________

A. A segment number & offset
B. An offset & value
C. A value & segment number
D. A key & value

In paging the user provides only ________ which is partitioned by the hardware into ________ and ______

A. One address, page number, offset
B. One offset, page number, address
C. Page number, offset, address
D. None of the mentioned

Each entry in a segment table has a ____________

A. Segment base
B. Segment peak
C. Segment value
D. None of the mentioned

The segment base contains the ____________

A. Starting logical address of the process
B. Starting physical address of the segment in memory
C. Segment length
D. None of the mentioned

The segment limit contains the ____________

A. Starting logical address of the process
B. Starting physical address of the segment in memory
C. Segment length
D. None of the mentioned

The offset ‘d’ of the logical address must be ____________

A. Greater than segment limit
B. Between 0 and segment limit
C. Between 0 and the segment number
D. Greater than the segment number

If the offset is legal ____________

A. It is used as a physical memory address itself
B. It is subtracted from the segment base to produce the physical memory address
C. It is added to the segment base to produce the physical memory address
D. None of the mentioned

When the entries in the segment tables of two different processes point to the same physical location ____________

A. The segments are invalid
B. The processes get blocked
C. Segments are shared
D. All of the mentioned

The protection bit is 0/1 based on ____________

A. Write only
B. Read only
C. Read €? write
D. None of the mentioned

If there are 32 segments, each of size 1Kb, then the logical address should have ____________

A. 13 bits
B. 14 bits
C. 15 bits
D. 16 bits

Explanation: To specify a particular segment, 5 bits are required. To select a particular byte after selecting a page, 10 more bits are required. Hence 15 bits are required.
