Verified Answer

For a set-associative Cache organization, the parameters are as follow...

Size of the loop = n × b = k × m × b

Size of a set = k × b (k − way associative)

Here, size of the loop is smaller than size of a set as . Now, however be the mapping (whether all be mapped to the same set or not), we are guaranteed that the entire loop is in cache without any replacement.
For the first iteration:

No. of accesses = n × b

No. of misses = n as each new block access is a miss and loop body has blocks each of size for a total size of .
For, the remaining 99 iterations:

No. of accesses = n × b

No. of misses = 0

So, total no. of accesses = 100nb
Total no. of hits = Total no. of accesses − Total no. of misses
= 100nb − n
So, hit ratio =

The hit ratio is independent if l, so for l = 1 also we have hit ratio = 1-

A company maintains records of sales made by its salespersons and pays them commission based on each individuals total sales made in a year. This data is maintained in a table with following schema:salesinfo = (salespersonid, totalsales, commission)In a certain year, due to better business results, the company decides to further reward its salespersons by enhancing the commission paid to them as per the following formula:If commission = 50000, enhance it by 2% If 50000 commission = 100000, enhance it by 4% If commission 100000, enhance it by 6%The IT staff has written three different SQL scripts to calculate enhancement for each slab, each of these scripts is to run as a separate transaction as follows:Q.Which of the following options of running these transactions will update the commission of all salespersons correctly
