* Multiuser: A computer system the can handle more then one user at a time. Windows is not a multiuser OS. It can handle only one user at a time. * Multitasking: The ability of an OS to do more then one thing at atime. for instance, you can be downloading a large file and still use another program to do something, like write a book. * Multiprocessing: The chip in new computers is able to do more then one task at a time because there is more then one processing unit on/in the chip.
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.
secret
Multiprocessing means the computer can do multiple processes parallel of each other (at the same time) with no performance degradation. Multiprogramming is an application that can be used to interface with different programming languages (java, C++, etc)
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.
single user os is that os which support only one user at a time and multi user os is that which support more than one user at the same time
Cooperative multitasking is multitasking tohelp someone else, while peemative multitasking is multiaatsking for yourself.
ALU stands for arithmetic and logic unit. The ALU does complex calculations, so by having two it gets the job done faster. This may not really make a difference if your an average user, although if you do AutoCAD and stuff that requires rendering then it will make a HUGE difference.
multitasking is doing more than two task or more. And combing task is two task
unix is a multiuser operating system but widows is a single user operating system.
multitasking: more task execute on sevaral cpumultithreading : sevaral part of one program execution
A symmetric multiprocessing (SMP) system is one in which each processor runs an identical copy of the operating system on each processor. In an asymmetric multiprocessing, system, each processor is assigned a specific tasks. An example of this would be a master- slave relationship between one processor and “the rest”.
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.
Parallel processsing ranges from instruction-level parallelism e.g. superscalar and VLIW to message-passing MIMD also called multicomputer, and also includes SIMD e.g. vector and array processing. Multiprocessing is specifically task parallelism, and is by definition shared-memory MIMD with multiple processor cores, sometimes multiple sockets.
the main difference b/w multiprogramming and multiprocessing O.S. is that the previous one is non-interactive O.S. and the later is interactive O.S. By-Satyam Maheshwari
moreprocessors, the more programms, maybe parallel or one for itself.needs a perfect programmer!good luck!bolliboy
use/ application
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.
