Answer:
Explanation:
a)
A compiler is a translator which transforms source language (high-level language) into object language (machine language). In contrast with a compiler, an interpreter is a program which imitates the execution of programs written in a source language.
b)
A scanner is an optional piece of computer hardware that uses reflected light to capture images and translate them into files a computer can read and display. Scanners come in high- and low-resolution versions, and can scan images in either black-and-white or color.
c)
the reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition.
d)
Defragmentation is like cleaning house for your server or PC, it picks up all of the pieces of data that are spread across your hard drive and puts them back together again. Why is defragmentation important? Because every computer suffers from the constant growth of fragmentation and if you don’t clean house, your server or PC suffers.
e)
General purpose application software is a type of application that can be used for a variety of tasks. It is not limited to one particular function. For example, a word processor could be classed as general purpose software as it would allow a user to write a novel, create a restaurant menu or even make a poster.
