In a 'single tasking' environment, only one task is given to the processor at a time & the processor takes millisecond to execute that task. For example, a student is writing a program which takes say, 10 minutes. During this time, the processor is sitting idle. When the program is given to the processor, it finishes its execution in a millisecond. This way, processor is wasting a lot of time which is a dawback in 'single tasking'.
In a 'Multi tasking' environment, processor time is divided equally. For example, there are 4 tasks to execute. This is divided into 1/4 millisecond time for each job. This small part is called 'time slice'. Within this time slice, it will try to execute each job. If it can't, intermediate result will be stored in temporary memory. Once executing the fourth task, it will come back to the first task, in a circular manner. This is called 'round robin' method.
The main difference is that, in single tasking, the processor time is wasted, but in multitasking, we can utilize the processor time in an optimum way.
multitasking is doing more than two task or more. And combing task is two task
no...its single task switching system...
When a person is task switching, they are working on one thing at a time. If a person is multitasking, they are working on more than one thing at once.
Preemptive multitasking is when the operating system preemptively interrupts a current task without cooperation. Cooperative multitasking is when the system must be programmed to do tasks.
Multitasking: The ability to execute more than one task at the same time is called multitasking. It involves only one CPU. Multiprogramming: The ability to execute more than one task but not simultaneously is called multiprogramming.
multitasking: more task execute on sevaral cpumultithreading : sevaral part of one program execution
Multitasking and Task switching are entirely different concepts. Multitasking is all about performing multiple tasks at the same time whereas, Task Switching can relate to moving from one task to another based on priority. Task Switching can be very closely associated to humans, as we have been doing it for quite a while now. While performing your daily tasks, you may be interrupted by another authority, which may lead you to switch tasks for a brief period. The disadvantage is you may lose the level of concentration you had earlier in the beginning. 'Multitasking' on the otherhand is associated with machines performing more than one task at a given time.
When you do two or more things at once, it is called multitasking. This can involve performing multiple tasks simultaneously or switching between different tasks rapidly. However, multitasking can reduce efficiency and focus on each individual task.
First of all there is difference between program and a task. There may be multiple tasks running related to one program at the same time. so if the processor is busy in multiple tasks related to one program then it is multitasking. But if the multiple tasks which the processor is executing concurrently are related to different independent programs then the concept is know as multiprogramming.

Dos is single user single task and windows single user multi task
The adjective for multi-task is multi-taskful.
