Unformatted text preview: achine (computer) and needs no translation programs (compiler, Assembler, Interpreter). Machine language is the language of binary digits 0’s and 1’s(“0” means “OFF” and “1” means “ON) that is why it is also called as binary language. It is very difficult to write programs using 0’s and 1’s i.e. in machine language. Thus machine language is totally machine dependent and is efficient for computers and inefficient for programmers. 7 ASSEMBLY LANGUAGE
The computer professionals developed one step higher language than the machine language which is called Assembly language .The binary codes of machine language (0’s and 1’s) were replaced by some special codes called mnemonics. The programs in Assembly language are written using these mnemonic codes as: ADD for addition, SUB for subtraction MUL for multiplication
These mnemonics are understandable by the human but not understandable by the machine. To make it understandable for the machine, a program called assembler is developed its function is to translate a program written in assembly language into machine language 8 2) High Level Language
These languages are fairly machine independent and English like. The programmer can understand more easily and enable the programmer to write instructions easily using English words and familiar mathematical symbols such as if
else, for, goto, +,- etc.
A program written in highlevel language is translated into machine understandable form with the help of Translation programs...
