COMPILERS INTERPRETERS AND ASSEMBLERS PDF

Below are the underlying details of how they differ from one another. What You Need To Know About Assembler An assembler is a program that takes basic computer instruction or instructions and then converts them into a pattern of bits that the computer processor can use to perform its basic operations. Usually, language used to program the assembler is referred to as assembly language. Assembler converts source code to an object code first then it converts the object code to machine language with the help of the linker programs.

Defination: Assembler computing , a computer program which translates assembly language to an object file or machine language format. It translates the high-level language to assembly language. Difference between Compiler And Interpreter Compiler Defination: A compiler is a computer program or a set of programs that transforms source code written in a programming language the source language into another computer language the target language , with the latter often having a binary form known as object code.

Compiler translates the entire high-level language program into the machine language program at one before executing it. This optimises the use of machine language instructions in the translated program. Therefore normally compiled programs run faster than Interpreted programs. The original high-level language program is called as source program. The compiled program i. Object code is permanently saved for future use. No time-consuming translation method. It requires large space in the computer.

Speed of a computer is very fast. Any change in source program after the compilation requires recompiling of the entire code. Interpreter Defination: In computer science, an interpreter is a computer program that directly executes, i.

The Interpreter translates the program written in high-level language into machine language at the time of executing that program, instructions by instructions. Then the CPU executes those machine language instructions. After that, the interpreter reads and translates the next instruction and so on. No object code is saved for future use. Time-consuming translation method. Interpreter is easy to write and do not require large memory space in the computer.

Speed is very slow. Any change in source program during the translation does not require retranslation of the entire code.

What are compilers, translators, interpreters, and assemblers?

Compiler, Interpreter, Assembler What is Compiler A compiler is a language translator that converts high level programs into machine understandable machine codes. In this process, the compiler converts the whole program to machine code at a time. If there are any syntactic or semantic error, the compiler will indicate them. It checks the whole program and displays all errors. It is not possible to execute the program without fixing those errors.
