MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The output of the assembler program is called the object code or object program relative to the input source program. The sequence of 0’s and 1’s that constitute the object program is sometimes called machine code.

Detailed explanation-2: -The output from the assembler can consist of an object module, a program listing, terminal messages, and an associated data file. The object module can be written to a data set residing on a direct-access device or a magnetic tape.

Detailed explanation-3: - A program written in assembly language is called. Source Program or Source Code. The program converted into machine language by the. assembler is called Object Program or Object Code.

Detailed explanation-4: -Assemblers and Compilers allow the source code to contain instructions to the compiler/assembler to control the way in which it operates or to ask it to do specific tasks. These are called “directives” and so not necessarilly produce object code, as normal lines of program do.

Detailed explanation-5: -Compiler-A program that translates source code into object code. The compiler derives its name from the way it works, looking at the entire piece of source code and collecting and reorganizing the instructions.
