Calculate cache hit ratio and average memory access
time using the formula presented below assuming that the total number of
requests is 3,056 and 540 of those requests are found in the cache. The Average
Cache Access Time is 50 sec and Average Main Memory Access Time is 70 sec.

Part B: Case Study: Efficient Memory Management
for MIT Database and OS Scheduling Algorithms

1.


A new memory management system needs to be incorporated
to make the existing system more efficient. The below memory diagram consists
of memory associated with the email addresses and names of students taking BN
104 course (referred as M1, M3, M6, M9 and M10 in Table 1).

Being an OS manager, your task is to evaluate memory
compaction and write down the base and limit registers assigned by the OS after
compaction. Also show the results in a new table.
