Programming Environment: From Text Editor to CPU Execution, Study notes of Computer Science

Montgomery CollegeComputer Science

An overview of a typical programming environment, detailing the role of various components such as disk, editor, preprocessor, compiler, linker, loader, cpu, and main memory. How program source code is created in an editor and stored on a disk, and how each component contributes to the creation of an executable file.

Main Memory
Program source code is
created in a text editor
and stored on disk
Preprocessor phase
scans source file,
processes directives,
makes substitutions, etc.
Compiler translates
statements into object
code in .obj or .o file
on disk
Linker phase combines
object code with library
code to create
executable: .exe in DOS/
Windows or a.out in
UNIX
Operating system
loader places program
machine code in
memory and sets CPU
instruction pointer
CPU executes
instructions, reads
and writes data, etc.
