Abstraction
A process of reducing complexity to formulate
generalised fundamental ideas or concepts removed
from specific details or situation. For example, the idea
that a cricket ball is a sphere in the same way that a
soccer ball is, or the concept that data can be
organised in records made up of fields irrespective of
whether the data are numbers, text, images or
something else.

Loop
In a loop structure, the program asks a question, and if the
answer requires an action, it is performed and the original
question is asked again until the answer is such that the action
is no longer required. For example, a program written to
compute a company’s weekly payroll for each individual
employee will begin by computing the wages of one
employee and continue performing that action in a loop until
there are no more employee wages to be computed, and
only then will the program move on to its next action. Each
pass through the loop is called an iteration. Loops constitute
one of the most basic and powerful programming concepts.
Lossless

A type of compression algorithm that retains sufficient

archival purposes.
Lossy Compression
A type of compression algorithm that compresses data
by discarding information that is not necessary to
reproduce the original data with sufficient detail for the
user not to notice the difference. It is used primarily for
reducing the size of multimedia assets such as video,
audio and photos, especially when streaming or
transmitting the data over the internet. The original
data cannot be restored from the compressed version,
as is noticeable when attempting to increase the size
of a compressed jpeg file.
Malware

relied on to help users detect and remove
