High & Low Level Languages

Describe high-level and low-level languages

1.      Low Level Languages

            Low-level languages are near to computer hardware and far from human languages. The two low-level languages are machine language and assembly language.

i.            Machine Language

            A type of language in which instructions are written in binary form is called machine language. It is the only language that is directly understood by the computer. It is the fundamental language of the computer.

ii.            Assembly Language

            Assembly language is a low-level language. It is one step higher than machine language. In assembly language, symbols are used instead of binary code. These symbols are called mnemonics. For example Sub instruction is used to subtract two numbers. Assembly language is also called symbolic language.

2.      High Level Languages

            A type of language that is close to human languages is called high level language. High-level languages are easy to understand. Instructions of these languages are written in English-like words such as input and print etc.
