As a operating systems junkie i don't see much difference in the both the OS. Both OSes provide all the functionality with respect to -

security (ACLs being absent in Windows that one difference)

Multiuser/Multitasking and Multithreading

Robust memory management in both

Device management

Process management

and so on. (Pretty much all the OS feature which one studies in OS 101)

The only difference i can think of with respect to enterprise OS capability of unix and windows i have seen Windows run only on Intel processors and power PCs to some extent. But Unix and its new buddy linux can run on practically all the zillion hardware platform making it the most proliferated OS ever.

Long live UNIX...

unix is an operating system which supports multithreading

the question u got is what is an threading - threading is nothing but like a process but it is more faster than a process

the threads are more efficient than the process because it share memory instead of systemcall

here u may got a doubt that what is a system call

a system call is invoked as a mediator between a process and operating system

threading flows in a sequential process

in threading wehave single threading and multiple threading

the best example i can give u is as we know that in unix many users share memory but they may not know that they are sharing.

here if a user have multi threading (that is he is using the unix)he need to complete a task i e.a sread sheet consist of different caluclations

if one row is changed entire complete spread sheet should be changed

so here for every task one thread is alloted so the task is completed more faster than a systemcall

unix is a multi threading and multi tasking

but where as a microsoft os is not a multitasking

in unix we have multi tasking that sharing memory among different

users but they will not know that they are sharing memory because of using different types of scheduling algorithms

1)FIFO(first in first out) Algorithm

2)round robin etc..... and so on

These both os are multihtread os not multprocessing.

Multiprocessing is not possible on single processor system.It's only possible on multcore or multiprocessor system where more then two process can be scheduled simulteniously .So system having one processor can not do multiprocessing it is only psedo-multiporcessing.

Winodow uses Priority based preemptive scheduling while Unix uses Round robin preemtive scheduling.

In windows process or thread which has higer priority will take over but this will be the case in Unix.They all will be in Q regardless of their priority.

Window is component based syste.TCP/IP and File system are the component of the system where Unix is integrated system.
