What is fixed partition multiprogramming?
Multiprogramming with fixed partitionsConsider the warehouse example again, multiple jobs of different types (perhaps size) entering storage in different partitions
- Several users simultaneously compete for system resources
- switch between I/O jobs and calculation jobs for instance
- To take advantage of this sharing of CPU, important for many jobs to be present in main memory
- Allowing Relocation and Transfers between partitions
- Protection implemented by the use of several boundary registers : low and high boundary registers, or base register with length
- Fragmentation occurs if user programs cannot completely fill a partition - wasteful.

Multiprogramming is a feature of an OS which allows runningmultiple programs simultaneously on 1 CPU. So, say, you may betyping in word, listening to music while in background IE isdownloading some file & anti-virus program is scanning. Theseall happen simultaneously to you. Actually programs don't …runsimultaneously, but OS divides time for each program according topriorities. When the chance of that program comes it runs, afterthe stipulated time is over, the next program runs & so on.Since this process is so fast that it appears programs are runningsimultaneously. Most of recent OSes are multiprogramming. For eg. Windows XP, Linux (MORE)
Answer . \nMultitasking, 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.\n. \nWhenever you have a program open and running, a rectangle with the name of that program appears on yo…ur 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. (MORE)
Answer . \nMultiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor. Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one p…rogram, then part of another, and so on. To the user it appears that all programs are executing at the same time.\n. \nIf the machine has the capability of causing an interrupt after a specified time interval, then the operating system will execute each program for a given length of time, regain control, and then execute another program for a given length of time, and so on. In the absence of this mechanism, the operating system has no choice but to begin to execute a program with the expectation, but not the certainty, that the program will eventually return control to the operating system.\n. \nIf the machine has the capability of protecting memory, then a bug in one program is less likely to interfere with the execution of other programs. In a system without memory protection, one program can change the contents of storage assigned to other programs or even the storage assigned to the operating system. The resulting system crashes are not only disruptive, they may be very difficult to debug since it may not be obvious which of several programs is at fault. (MORE)
Task is defined as a system program which consumes very less system resources(memory, CPU time, HD etc..). A task should have periodic activity and event based activity. Assume a printer which takes 10msec to print each line and you have fired a job to the printer.So the CPU should send every line w…ith a 10msec gap. But transmitting a line to the printer is an output operation, which means the CPU has to execute some instrucions in order to transmit a line to the printer. Assume that the CPU takes 2usec to execute this. So this 2us is nothing but a sysem resource. So this is called as task since it is making less usage of system resource and it is periodic(every 10msec it has to execute instructions) and it is also event based(it has to check whether the printer is ON/OFF) Dos: Mutlitasking (can do printing and scanning simultaneously) but not multi programming(it can execute only one c/c++/java etc program in memory) Unix: Multiprograming and hence multi tasking. Answer Multitasking and Multiprogramming: In multiprogramming, more than one program lies in the memory i.e. in terms of operating system, the schedular selects the jobs to be placed in ready queue from a number of programs. The ready queue is placed in memory and the existence of more than one program in main memory is known as multiprogramming. Example of multiprogramming, we open word, excel, access and other applications together but while we type in word other applications such as excel and access are just present in main memory but they are not performing any task or work. Or we can say that are not being used at the same time. Whereas multitasking means performing multiple tasks in parallel. Usually, CPU processes only one task at a time but the switching of CPU between the processes (also known as Context Switching) is so fast that it looks like CPU(or processor) is executing multiple processes at a time. Example of multitasking, we listen to music and do internet browsing at the same time (they execute parallely). Also a task (or process) is a part of program under execution. In other words, task is an active entity where as program is passive entity. (MORE)
Answer . Multiprogramming is the act of writing programs that can be scheduled for running on more than one processor (either on a multiprocessor system, or in a clustered environment such as MOSIX).\n. \nBatch-Processing is when a certain set of programs are executed, in orderly form,\nwith the… results of one program typically being fed into the following program, without any interaction from the user -- as apposed to interactive programs which requires user input at certain stages in order for the program to continue.\n. \nBatch-processing can also involve the use of multiprogrammed applications, provided they can be run in a non-interactive mode.

multiprogramming lets you do more than one thing at a time ans multiprogramming is also called multi-threading here more than one operation in a program takes place..
Answer . Multiprogramming makes effifcient 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.

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)
In computer systems, the term "partition" refers to a segmentation or separation of the data storage space on a disk. The most common usage for a hard disk is simply one partition accounting for 100% of the storage space. In a windows system, this would be your drive C: If, for some reason it was… desired to split that drive into two, you could instead make two partitions and split the space 50/50 or 60/40 90/10 whatever, and have drive C: for one and D: for the other. Indeed you can separate the hard disk into dozens of partitions and have drive letters all the way to Z: but this tends to get a bit cumbersome. Many operating systems prefer to put system files and user files into separate partitions for various reasons, and might also have a 3rd partition for swap files. This is done to boost system performance and stability. In cases where there are multiple operating systems running on a single computer system, it is common to have each installed on their own partition of the hard disk.. (MORE)
multiprograming in terms of a computer system refers to the execcution of 1 or more programs by the system in the background(i.e. not in realtime), with the user having no interaction with the programs being executed. eg. THE CLOCK TIMER OF THE COMPUTER SYSTEM
Answer Creating a section on a drive to store data. You could have a partition to run XP and another to run Vista for example. You could have a partition just to store pictures as opposed to a file ECT.
what is multiprogramming system in operating system? where more than one program can pe execute at one time We know that there must be enough memory to hold the OS (resident monitor) and one user program. Suppose that there is room for the OS and two user programs. When one job needs to wait f…or I/O, the processor can switch to the other job, which is likely not waiting for I/O ( Figure 2.5b ). Furthermore, we might expand memory to hold three, four, or more programs and switch among all of them ( Figure 2.5c ). The approach is known as multiprogramming , or multitasking . It is the central theme of modern operating systems. http://www.freeimagehosting.net/fox67 . . Figure 2.5a illustrates this situation, where we have a single program, referred to as uni-programming. The processor spends a certain amount of time executing, until it reaches an I/O instruction. It must then wait until that I/O instruction concludes before proceeding.

1. better performance-shorter response time & higher throughput 2. Better Reliability-if one processor brekdown then other takes its workload
A disadvantage of fixed partitions is the severe limitation thatoccurs through the fixed or allocated space in the particulardivision. Another disadvantage of this is the loss of magnetic discspace of the total disk space available when running differentoperating systems on the same hard disk.
Multi programming is to open the more than one programme in one computer system.. Muli tasking is to use the more than one programme in one computer system.
That would mean you could have many users running many programs using the same OS that is running on many processors. .

Fixed partitioning is a way for an operating system to assign mainmemory to processes. In a fixed partition, each process is given apre-determined amount of the memory, called a partition.
Yes, multi-programming is possible without any interrupts. Providedthat a given type of code is properly written thenmulti-programming is possible without any interrupts.
Multitasking is being able to do more than one thing at a time.. Multiprogramming is using more than one 'language' to accomplish a task.
using multiprogramming we can save the time multiprogramming resources to more than one current application i.e we can run multiple applications at a time that's way we refuses the time

The difference between fixed partition and dynamic partition.... For the case of disk partitions: . Fixed partitions are defined in the master boot record, or in one of its chains that define logical partitions in an extended partition. As such, they are known at boot time and, if the operating sy…stems recognize them, they can be shared between multiple installations, such as Windows and Linux.. Dynamic partitions are defined by the operating system. They are defined out of unallocated drive space and, as such, are not known at boot time. They can not generally be shared between different installations. Also, unless the operating system using dynamic partitions makes at least its allocations known to the boot record, any attempt to manage disc space using both techniques is dangerous.. For the case of analysis and programming: . Partitioning is a technique used to break data up into managable pieces. Binary Search, for instance, partitions an array into successively smaller pieces as it narrows its search space down. Sorting can also partition data, sorting each partition and then sorting the partitions. Quick Sort and Merge Exchange Sort are examples of that. Statistical analysis may also partition data. The list is endless. Addressing the specific question, then, static partitioning is breaking the data up into fixed sized pieces, while dynamic partitioning makes the piece size variable, often as a consequence of the results as they evolve.

A fixed partition cannot be moved or expanded; therefore, one advantage would be that you know how much space can be used, and might keep better track of what you are using. The disadvantage is that it cannot be expanded; once you run out of space it takes a bit of work to get a larger partition,… and that may not be possible if the physical space is exceeded. (MORE)
Will allowing Ubuntu's GParted partition manager to fix the file system on an NTFS partition running Windows XP cause any data loss?
GParted is a very well-tested program and is unlikely to cause data loss during normal operation; the warning is mainly important only if the process is interrupted or the hard drive is physically damaged. NTFS is not well-supported, so it is particularly paranoid when working with NTFS partitions. …Actually, it is so paranoid it is unlikely to be able to fix a problem with the file system, and can usually only work with partitions that have already been checked by Windows.

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. (MORE)

A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time. . The main memory (which is the volatile memory where active programs and data are held during use), is divided into par…titions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run.. So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size.
