Q1. Describe the concept of memory segmentation which is used in the memory management.
Q2. Describe different page replacement policies with reference to the memory management.
Q3. Assume that a SRAM consists of an access time of 5 ns. DRAM with an access time of 60 ns and disk space with access time of 7 msec. If the hit rate at each level in the memory hierarchy is 80 % (apart from the last), illustrate the average memory access time? Determine the average memory access time if the hit rates at each level apart from the last is 90%.
Q4. Describe how processes are synchronized in the shared memory computers.
Q5. Describe the difference between the superscalar and very large instruction word (VLIW) architecture in terms of the hardware and software requirement.
