process vs task

Hi,

I am new to this forum and unix too. I have just started learning unix. As I was going through the first chapter, I read that unix is multitasking, multiprogramming, multiprocessing and multiuser OS.

My question is: Is there any difference between a TASK and a PROCESS. How are PROCESS IDENTIFICATION NUMBERS and TASK NUMBERS different?

I searched on google for two days but yet confused..... Please help me.

Thanks in advance

Multitasking means concurrent execution of programs. A task can be a process or a thread, depending on the operating system
(if you want to learn this question more deeply read Maurice J. Bach, The Design of the Unix Operating System)
