Answer:
Software aspect of computing
Explanation:
Boole never regarded logic as a branch of mathematics, instead, he proposed that logical propositions should be expressed as algebraic equations. Mathematical operations were replaced with AND, OR.
Boolean algebra provides the basis for analyzing the validity of logical propositions because it captures the two-valued character (binary: (1 or 0) ) of statements that may be either true or false which is very important for all digital computation of which softwares are part of.

Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
