MultiTasking:
In MultiTasking operating system, several jobs are executed in parallel by the operating system, through multiple processors (or) CPUs only.
Like .
CPU1: Job-A
CPU2: Job-B
CPU3: Job-C
Multiprogramming :
The method of Multiprogramming systems comes in the 1960s. In that process several different programs in batch were loaded in the computer memory, and the first one began to run. One program after another executed when the first program reached an instruction waiting for a device that has a message, the context of this program was stored away, and the second program in memory was given a chance to run. The process continued until all programs finished running.

What are the differences between multitasking and multiprogramming?
Task is defined as a system program which consumes very less system resources(memory, CPU time, HD etc..).A task should have periodic activity and event based activity.Assume a printer which takes 10msec to print each line and you have fired a job to the printer.So the CPU should send every line with a 10msec gap. But transmitting a line to the printer is an output operation, which means the CPU has to execute some instrucions in order to transmit a line to the printer.Assume that the CPU takes 2usec to execute this. So this 2us is nothing but a sysem resource. So this is called as task since it is making less usage of system resource and it is periodic(every 10msec it has to execute instructions) and it is also event based(it has to check whether the printer is ON/OFF)Dos: Mutlitasking (can do printing and scanning simultaneously) but not multi programming(it can execute only one c/c++/java etc program in memory)Unix: Multiprograming and hence multi tasking.AnswerMultitasking and Multiprogramming: In multiprogramming, more than one program lies in the memory i.e. in terms of operating system, the schedular selects the jobs to be placed in ready queue from a number of programs. The ready queue is placed in memory and the existence of more than one program in main memory is known as multiprogramming.Example of multiprogramming, we open word, excel, access and other applications together but while we type in word other applications such as excel and access are just present in main memory but they are not performing any task or work. Or we can say that are not being used at the same time.Whereas multitasking means performing multiple tasks in parallel. Usually, CPU processes only one task at a time but the switching of CPU between the processes (also known as Context Switching) is so fast that it looks like CPU(or processor) is executing multiple processes at a time.Example of multitasking, we listen to music and do internet browsing at the same time (they execute parallely).Also a task (or process) is a part of program under execution. In other words, task is an active entity where as program is passive entity.

Why windows is multitasking and UNIX is multiprogramming?
Not really a true statement; both Windows and UNIX have multi-tasking and multi-programming capabilities.
What is the difference between UNIX and other operating system?
Unix is a multi user, multi processing and multi tasking operating system
Multi-programming or multi-tasking enables more than a single process to apparently execute simultaneously How is this achieved on a uniprocoessor?
The two approaches allow to achieve pseudo-concurrrency on a single processor. They are just slightly different in their approach. Here is the slight difference: http://en.wikipedia.org/wiki/Multiprogramming
Unix terminology for multi-tasking?
Multi-tasking is multi-tasking, regardless of the Operating System you are talking about. The use of multi-tasking is controlled via a facility in Unix called "Job Control", which allows a user to start multiple tasks, move them between background and foreground, kill them off, etc.
Multitasking vs Multiprogramming?
Multi programming is to open the more than one programme in one computer system. Muli tasking is to use the more than one programme in one computer system.

What is the difference between multitasking multiprogramming and multiprocessing in operating systems?
Multi-tasking means doing more than one task at a time; such as printing, burning c.d's, etc. all at the same time. Multi-programming means running more than one program at one time; such as Microsoft word, AOL, Windows Media Player, all at one time. Multi-processing means that your computer can process more than one thing at a time.
Do the words multi and tasking need a hyphen between them?
I do not believe that multitasking is supposed to have a hyphen.
