When a user initiates to execute a program, the
operating system creates a process to represent
the execution of this program. The creation of
executable programs include so many steps :
– The source code (a program is written in
programming languages) is translated into
object program or object modules with the help
of translator or compiler.
– The relocatable object modules converted to
absolute programs by linker.
– The absolute programs are converted to
executable programs by loaders.
– Then processor executes this program. A
processor is in executing is said to be a process.
– The process consists of the machine code image
of the program in memory, and the PCB
(Process Control Block) structure.
