Should real time operating system be necessarily multiprogrammed?

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.....


Diffirence between multiprogamming and multitasking?

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.


What is the difference between multitasking and multiprograming?

Multitasking is being able to do more than one thing at a time. Multiprogramming is using more than one 'language' to accomplish a task.

What is the difference between multitasking and multiprocessing?

Multiprocessing / multitasking Multiprocessing is the use of two or more processors in a single computer. to acheive greater throughput, economy of scale and increased reliability.Most multiprocessing systems use symmetric multiprocessing, SMP, (as opposed to asymmetric) where all processes share the processing load equally. Multitasking on the other hand is best explained by first defining what multiprogramming is. Multiprogramming is used to ensure the best effecient use of the CPU. Whenever a CPU is processing a program, which is loaded in memory, and it must wait for resources or I/O then it will sit idly which is a waste of the CPU. Multiprogramming will store a number of 'jobs' in a queue and whenever the CPU is waiting for I/O etc while executing a particular job, it will immediately open the next job in the queue and process that job until such time as it must wait again, and then it can select the next job in the queue or return to the previous job. In this way the CPU idle time is reduced. Multitasking is a logical extension of multiprogramming in that instead of waiting for a process to reach a stage where it must wait for I/O or some resource, it schedules time for each process that is loaded into memory, such that each process appears to the user to be running at exactly the same time.Another name for multitasking is timesharing.


'What is the difference between multiprogramming and multitasking and what is meaning of a task if we consider a task as a program then the concept will be multiprogramming then what is the differenc?

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.

When we say a system is a multiprogramming system?

Multiprogramming is collecting several jobs in a job pool and the OS selects the job from the pool so that the CPU has one job to execute , in case of any IO request for the job in execution the CPU switches to another job here switching is less compared to multitasking.So a computer system which allows such type of switching in between jobs is called a multiprogramming system. Please make note that multitasking is done by user but multiprogramming is done by operating system only.


What is difference between uni-programming and multiprogramming?

multiprogramming or multitasking means more than one program can execute at the same time. It is the allocation of a computer system and its resources to more than one application at the same time. However in uni-programming you can have only one program running at any point in time.


What is the difference between Real time system and Multiprogrammed system?

Time Sharing 01. Time Sharing is the logical extension of multiprogramming, in this time sharing Operating system many users/processes are allocated with computer resources in respective time slots. Multiprogramming 01. Multiprogramming operating system allows to execute multiple processes by monitoring their process states and switching in between processes. Time Sharing 02.Processors time is shared with multiple users thatโ€™s why it is called as time sharing operating system. Multiprogramming 02.Processor and memory underutilization problem is resolved and multiple programs runs on CPU thatโ€™s why it is called multiprogramming. Time Sharing 3. In time sharing OS system depends on time to switch between different processes. Multiprogramming 3. In Multiprogramming OS, system depends on devices to switch between tasks such I/O interrupts etc. Time Sharing 4. System model of time sharing system is multiple programs and multiple users. Multiprogramming 4. System model of multiprogramming system is multiple programs. Time Sharing 5. In this process, two or more users can use a processor in their terminal. Multiprogramming 5. In this, the process can be executed by a single processor. Time Sharing **6.**Time sharing OS has fixed time slice. Multiprogramming 7. Multi-programming OS has no fixed time slice. Time Sharing **8.**Time sharing system maximizes response time. Multiprogramming 8. Multiprogramming system maximizes response time. Time Sharing 9. Example: Windows NT. Multiprogramming 9. Example: Mac OS.

What is multitasking or multiprogramming?

Multitasking, is, simply, doing more than one thing at the same time. In the context of computer science, it means having one or more programs open and running at the same time. Whenever you have a program open and running, a rectangle with the name of that program appears on your task bar (the silver, bar which runs across the bottom of your computer screen - with the Start button on the left). If you only have one program open, only on rectangle (button) appears on the task bar and you are not "multitasking." If you have more than one program opened, more than one button will appear, and you are multitasking.


What are advantages of multiprogramming over non multiprogramming?

Multiprogramming is the rapid switching of the CPU between multiple processes in memory. It is done only when the currently running process requests I/O, or terminates. It was commonly used to keep the CPU busy while one or more processes are doing I/O. It is now mostly superceded by multitasking, in which processes also lose the CPU when their time quantum expires. Multiprogramming makes efficient use of the CPU by overlapping the demands for the CPU and its I/O devices from various users. It attempts to increase CPU utilization by always having something for the CPU to execute. The prime reason for multiprogramming is to give the CPU something to do while waiting for I/O to complete. If there is no DMA, the CPU is fully occupied doing I/O, so there is nothing to be gained (at least in terms of CPU utilization) by multiprogramming.

What is the difference between multitasking and multiprogramming?

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 time
