MIND MAPS
A Mind Map is a tool that allows us to organise ideas, thoughts or concepts and their relationship
in a graphical manner.
After the brainstorming session is over, we structure the ideas and information, and their
relationship using Mind Maps. In this technique, we pick up the ideas that have common features.
These ideas are then grouped under one category, and the different categories are linked to the
main topic using lines or arrows. Let us draw a Mind Map for the computer:

COMPUTER LANGUAGES
Human needs a common language to communicate with each other. Similarly, computers need
a language to communicate with its user, take instructions and to perform operations. The
language that is required by a computer is called computer language. This is also known as a
programming language.
It is a set of words, symbols and codes that the computer can understand. There are a number of
programming languages worldwide. Computer languages are classified into two major categories:
Low-level language and High-level language.
LOW-LEVEL LANGUAGE
Low-level language is a programming language that deals with the computer’s hardware
components. It is machine-dependent. A set of low-level language instructions written for a
particular type of computer will not work on a computer with a different design. These languages
are also known as computers’ native languages.
There are two categories of low-level languages:
