Answer:
it is important for software to be compatible with your operating system so that you can use the software you acquired. The complications you may encounter if your software is not compatible with your operating system would be error codes, money wasted, and/or possible system changed that you do not want to change since it wouldn't be appropriate for your operating system.
Explanation:
Incompatible software is not something you should use with your operating system.

The answer is provided in the form of explanation
Explanation:
A page fault occurs means that the required page is not in main memory. First OS check for
page in the cache memory, if the page is present then retrieved but if not present then check for
page in main memory and if the page is not present here too then it searches for page in hard
drive. To calculate the expected time, the following formula is used:
Cache hit ratio = 95% = 0.95
Cache miss ratio = 5% = 0.05
Cache access time = 2 millisecond
The average access time of hard drive = 30 milliseconds
Expected time = Hit ratio (cache access time +memory access time) + Miss ratio (cache
access time + 2 * memory access time)
= 0.95 (2+30) + 0.05 (2+2*30)
= 0.95 (32) + 0.05(62)
=30.4 + 3.1
= 33.5 millisecond
Expected time = cache hit ratio * cache access time + (1 – hit ratio) * cache miss ratio
= 0.95*2+(1-0.95)*0.05
= 1.9025
Answer:
ALU
Explanation:
Arithmetic Logic Unit (ALU) is the part of the microprocessor that performs arithmetic operations, such as addition, subtraction, AND, OR, NOT, XOR etc. ALU is also used for comparison of input numbers.
<u>HOW IT WORKS:</u>
When the code is compiled, the code is converted first to assembly language and then assembly language is converted to machine code.
In Machine language, each arithmetic or logic operation has a specific code known as OPCODE. This opcode tells ALU which operation to perform on the inputs.
