1. 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 native language of the compute.
Sometimes machine language referred to as machine code or object code, machine language is a collection of binary digits or bits that the computer reads and interprets. Machine language is the only language a computer is capable of understanding
A program written in machine language can be executed very fast by computer. The computer does not need any translator to understand this language. The programs written in machine language are machine language dependent. Every computer has its own machine language.
Computer programs are written in one or more programming languages, like C++, Java, or Visual Basic. A computer cannot directly understand the programming languages used to create computer programs, so the program code must be compiled. Once a program’s code is compiled, the computer can understand it because the program’s code has been turned into machine language.
For example: Machine language (binary) for the text “Hello World”.
