A 'process' is an execution stream in the context of a
particular process state.
An execution stream is a sequence of instructions.
Process state determines the effect of the instructions. It
usually includes (but is not restricted to):
Registers
Stack
Memory (global variables and dynamically allocated memory)
Open file tables
Signal management information
*Key concept: processes are separated: no process can
directly affect the state of another process.
->Process is a key OS abstraction that users see - the
environment you interact with when you use a computer is
built up out of processes.
The shell you type stuff into is a process.
When you execute a program you have just compiled, the OS
generates a process to run the program.
even Your WWW browser is a process.
