Multiprogramming is a method of running several different programs in a computer apparently at the same time.
Usually on a mainframe - the computer has a number of programs loaded into memory and the operating system switches quickly between them, processing a little bit of each one in turn. The high speed of the processor makes it seem like more than one program is being run at the same time.
On a PC it is usually called multitasking.
Answer-multitasking is the process which occur when more than one task(job) are executed by CPU at a time....-.Multitasking should not be confusing with multiple program where by in multiprogram more than one program(task) are in the mein memory but each one are executed by CPU at different time...It is impossible CPU to running more than one program at the same timeno of tasks can be done at a time is called multi tasking no of programmes can be executed in a single system is called multi programming
Multitasking is being able to do more than one thing at a time. Multiprogramming is using more than one 'language' to accomplish a task.
Time sharing
MULTIPROGRAMING .................. The term multiprograming denotes an operating system that,in addtion to supporting multitasking. In multiprograming more than one jobs are active in memory.Within a very small period more than one jobs are executed simultaneously. MULTITASKING ............... In general multiprogramming implies multitasking,but multitasking does not imply multiprogramming. A multitasking operating system is distinguished by its ability to support concurrent execution of two or more active processes. as discussed actually both multitasking and multiprogramming are same no other answer mentioned are justifiable.....
Cooperative multitasking is multitasking tohelp someone else, while peemative multitasking is multiaatsking for yourself.
multitasking is doing more than two task or more. And combing task is two task
multitasking: more task execute on sevaral cpumultithreading : sevaral part of one program execution
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.
The difference between Batch System, Real Time System and Multitasking System is that they are cool and you are a gimp.
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.
secret
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.
I do not believe that multitasking is supposed to have a hyphen.
-> Difference between process based and thread based multitasking: 1) threads share the same address space where as process doesn't. 2) context switching between threads is usually less expensive than between processes. 3) cost of communication between threads is relatively low.
