Humans need a common language to communicate with each other. Similarly, computers
need a language to communicate with its user, take instructions, and perform operations. The
language that is required by a computer is called computer language. This is also known as a
programming language.
A computer language is a medium by which instructions are transmitted to the computer to
perform a specific task. It is a set of words, symbols and codes that the computer can understand.
A computer program is a set of instructions written in a programming language. There are a
number of programming languages worldwide.
Computer languages are classified into two major categories: Low-level language and High-level
language.
