Hi all,
1) I have a small doubt in Linux Basics.
Wether the Linux having threading concept ?
The Linux kernel doesn't, everything in Linux is a process.
I heard Linux treat everything as a process ? Is it true ?
Yes
If not how can i found that linux suppport threading concept ?
Processes in Linux can share certain resources with other processes.
Libraries like pthread make use of this feature to bring threads to
user-space. Threads in Linux are processes that share their process
address space with other processes.
For a mored detailed explication have a look at

2) I would like to know the difference between Process/Thread and
Task.
Task: AFAIK there is no official definition, i'd say something like
"unit of concurrency"
Process: Each process has it's own address space
Thread: A thread shares it's address space with other threads

Matthias
