ITPEC IP April 2019 Question 17
ITPEC IP April 2019 — Question 17 of 100
The minimum required virtual memory is 1,132 Mbytes. The OS needs 200 Mbytes. Eight concurrent applications need 50 × 8 = 400 Mbytes. Memory-control functions require the 512 Mbytes of main memory plus another 20 Mbytes. Therefore the total is 200 + 400 + 512 + 20 = 1,132.
Answer (d)
Why not others:
- 762 and 782 omit part of the stated application or memory-control requirement
- 1,112 omits the additional 20 Mbytes
Key rule: Follow the stated total definition exactly and include every component before selecting the option.
