Answer:
Computer systems consist of three components as shown in below image: Central Processing Unit, Input devices and Output devices. Input devices provide data input to processor, which processes data and generates useful information that's displayed to the user through output devices. This is stored in computer's memory.
Answer:

Explanation:
Given

Required
Write an equivalent expression in C

Arguably, there wasn't any publishing before movable type and printing presses.
HI!the resaon why should you care for you sense organs is that they help us to contact with our surroundings.
Answer:
Spends more of its time seeking I/O operations than doing computational work.
Explanation:
The I/O bound process are depend on Input and output speed. on the other hand computational work is associated with CPU bound processes. Therefore option "C" is better option for I/O bound processes.
