Code segment
The code segment is the part of an application program that contains the explicit machine codes ( opcodes ) that are sent to the processor and then executed. A code segment therefore contains instructions (commands) for the computer that it should execute.
The code segment is translated from the application's source code by the compiler . Source code ( assembler code ) can be recovered from the code segment with the aid of a disassembler . The term “code segment” denotes both the instruction area in the program file and the area of the main memory with the program loaded for execution.
After the program has been loaded by the operating system , the processor processes the commands in the code segment step by step until an abort condition occurs in the application , which initiates the termination of the application.
