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:

Machine Language

Machine language is the only language understood by the computer. It is also known as
the first generation language (1GL). Machine language is very difficult for programmers
to use because it only consists of two digits, 0 and 1, called binary digits or bits. Where the
bit ‘0’ represents the OFF state and the bit ‘1’ represents the ON state.
