A $$1000$$ Kbyte memory is managed using variable partitions but to compaction. It currently has two partitions of sizes $$200$$ Kbytes and $$260$$ Kbytes respectively. The smallest allocation request in Kbytes that could be denied is for

In a virtual memory system the address space specified by the address lines of the $$CPU$$ must be __________ than the physical memory size and _______ than the secondary storage size.

The capacity of a memory unit is defined by the number of words multiplied by the number of bits/word. How many separate address and data lines are needed for a memory of $$4K\,\, \times \,\,16?$$

The address sequence generated by tracing a particular program executing in a pure demand paging system with $$100$$ records per page with $$1$$ free main memory frame is recorded as follows. What is the number of page faults?

$$0100, 0200, 0430, 0499, 0510, 0530, 0560, 0120, 0220, 0240, 0260, 0320, 0370 $$
