ventional computers, translation of the program or the source code into object/machine code is done by various methods which include  assembler, compiler and interpreter.  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.                                           OR ASSEMBLER An assembler is a program that converts assembly language into machine code. It takes the basic commands and operations from assembly code and converts them into binary code that can be recognized by a specific type of processorcode. F
