Answer:
a) AL will contains 0011 1100
Explanation:
In assembly language, shifting bits in registers is a common and important practice. One of the shifting operations is the SHR AL, x where the x specifies that the bits be shifted to the right by x places.
SHR AL, 2 therefore means that the bits contained in the AL should be shifted to the right by two (2) places.
For example, if the AL contains binary 1000 1111, the SHR AL, 2 operation will cause the following to happen
Original bit => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) | (0) |
Notice;
(i) that there are two shifts - one at a time.
(ii) that the bits in bold face are the bits in the AL after the shift. Those that in regular face are those in the carry flag.
(iii) that the new bits added to the AL after a shift are the ones in bracket. They are always set to 0.
The notation would be O (n-1) because there would be no need to compare with the first bit however this notation is most commonly noted as O (n) but the first is also technically correct
You can just put “/“ to represent dividing
Answer:
Yes.
Explanation:
Race condition can be described as a situation where at any time there are two or more processes or threads operating concurrently, there is potential for a particularly difficult class of problems. The identifying characteristic of race conditions is that the performance varies depending on which process or thread executes their instructions before the other one, and this becomes a problem when the program runs correctly in some instances and incorrectly in others. Race conditions are notoriously difficult to debug, because they are unpredictable, unrepeatable, and may not exhibit themselves for years.
