What is difference between Compiler, Interpreter and Assembler?

Compiler:

• A Compiler is a program used in High level language to convert the low level language or machine code into binary information.

• A Compiler is faster and occupies more memory.

• Compiler checks to entire program at once, if no error then sends for execution.

Interpreter:

• An interpreter is a program used High level language to convert the low level language or machine code into binary information.

• An interpreter is slow comparison as compiler occupies less memory because it is used in Graphics based programming software.

• An interpreter checks the program line by line. After checking one line it checks the second and so on. After checking all line it sends to execute.

Assembler:

• Assembler is converting to high level language into assembly level language. i.e it converts the Mnemonic symbol into object code and send for execution.

• It is faster than machine level information and consumes less memory.

• Assembler is used code add for Addition, sub for subtraction etc.
