What are the differences between multiprogramming, multiprocessing, multitasking, multiusers system.?

Answer 1

Multiprogramming- Jobs to be executed are loaded into a pool. Some number of those jobs are loaded into main memory, and one is selected from the pool for execution by the CPU. If at some point the program in progress terminates or requires the services of a peripheral device, the control of the CPU is given to the next job in the pool. As programs terminate, more jobs are loaded into memory for execution, and CPU control is switched to another job in memory. In this way the CPU is always executing some program or some portion thereof, instead of waiting for a printer, tape drive, or console input

Multiprocessing - the simultaneous execution of two or more programs or instruction sequences by separate CPUs under integrated control

multitasking System - the concurrent or interleaved execution of two or more jobs by a single CPU.

Multiusers System - a computer system in which multiple terminals connect to a host computer that handles processing tasks.

Answer 2

multiprogramming is a form of processing in which a computer holds more than one program in memory and works on them in round-robin fashion that is, by sharing out the processor's time so that each program receives some attention some of the time. This way of working is in contrast to using the processor to run one program at a time.

Multiprocessing is 1) Refers to a computer system's ability to support more than one process (program) at the same time. Multiprocessing operating systems enable several programs to run concurrently. UNIX is one of the most widely used multiprocessing systems, but there are many others, including OS/2 for high-end PCs. Multiprocessing systems are much more complicated than single-process systems because the operating system must allocate resources to competing processes in a reasonable manner.

multitasking is 1. A mode of operation offered by an operating system in which a computer works on more than one task or application at a time. 2. Also can describe people who excel at juggling several tasks at once, as opposed to those who work from task to task in a linear fashion.

multiusers means that different users in the system

Answer 3

hi,

Here is a explain:
multiprogramming is that a programm was created in multi programming language. like Mobile service provider is use.

Multiprocessing is that a single time a computer is running with more than one process. Every computer is multiprocessing now a day. In older time it is not.

Multitasking is that you are working on computer & you are using more than one programm or software or talk a same time. like you are using MS word, MS excel, a game, or playing music while you on computer.

Multiuser is that a computer is running with more than one user. like highend server.

Good luck!!!!

Answer 4

multi- proramming is nothing
proccessing is when your using a DUal COre proccessor - its the future, 2 brains in one
multitasking is the ability to do ten things at once without each thin lagging the others down (this is accomplished with a dual core proccessor
multi user, is self explanitory - a system that many can access - like Y!A

Answer 5

multi means "multiple" so if it is
multiprogramming=it runs multiple programs
and so on and so forth.....running all at the same time

Answer 6

don't know don't know and still don't know but let 'em 2 points be deposited in my account please...damn just read your prefixes or root words or simply just search sometimes..dummy

Answer 7

it would take multiple hours to discuss your multilevel question. i consider myself to be multifaceted by come on!!!!...
