Answer:
Direct Mapped Cache
Explanation:
Given that a Direct Mapped Cache is a form of mapping whereby each main memory address is mapped into precisely one cache block.
It is considered cheaper compared to the associative method of cache mapping, and it is faster when searching through it. This is because it utilizes a tag field only.
Hence, The method of mapping where each memory location is mapped to exactly one location in the cache is "Direct Mapped Cache"
Answer:
The answer is below
Explanation:
a)
If the blocks of a file are not put together, that is for nonadjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (average seek + rotational latency + transfer time) * 100 block
Average seek = 5 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec
t = (5 + 10 + 0.02) * 100 = 1502 msec
b)
If the blocks of a file are put together, that is for adjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (seek time * mean interblock distance + rotational latency + transfer time) * 100 block
seek time = 100 microsec = 0.1 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec, mean interblock distance = 2 cylinders
t = (0.1*2 + 10 + 0.02) * 100 = 1022 msec

Answer:
False
Explanation:
The definition for the If-Then-Else structure is as follows:
IF (<em>boolean_condition</em>)
THEN (<em>commands_for_true</em>)
ELSE (<em>commands_for_false</em>)
When there is an ELSE sentence, its commands are to be executed whenever previous conditions where not evaluated as true
