6 Describe the differences between symmetric and asymmetric multiprocessing?
Asymmetric multiprocessing - In asymmetric multiprocessing (ASMP), the operating system typically sets aside one or more processors for its exclusive use. The remainder of the processors run user applications. As a result, the single processor running the operating system can fall behind the processors running user applications. This forces the applications to wait while the operating system catches up, which reduces the overall throughput of the system. In the ASMP model, if the processor that fails is an operating system processor, the whole computer can go down. Symmetric mMultiprocessing - Symmetric multiprocessing (SMP) technology is used to get higher levels of performance. In symmetric multiprocessing, any processor can run any type of thread. The processors communicate with each other through shared memory. SMP systems provide better load-balancing and fault tolerance. Because the operating system threads can run on any processor, the chance of hitting a CPU bottleneck is greatly reduced. All processors are allowed to run a mixture of application and operating system code. A processor failure in the SMP model only reduces the computing capacity of the system. SMP systems are inherently more complex than ASMP systems. A tremendous amount of coordination must take place within the operating system to keep everything synchronized. For this reason, SMP systems are usually designed and written from the ground up.
Who is developing the operating system?
Operating systems are developed by 3 major companies. Microsoft makes Windows, Macintosh makes macs, and Linux makes Linux operatin systems. There are a variety of versions of each OS.

Difference between asymmetric and symmetric multiprocessing and simple multiprocessors?
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”.
Distinguish between multiprogramming and multi processing What are the key motivations of development of each?
Don't tell me what to do.
Can motivate forgien direct investment?
There are many factors that motivate foreign direct investment. The main point of motivation is the competitiveness to obtain the foreign direct investments within each developing country.
What is the difference between timesharing and multiprocessing?
Multiprocessing is a generic term for the use of two or more central processing units (CPUs) within a single computer system. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined. The term multiprocessing is sometimes used to refer to the execution of multiple concurrent software processes in a system as opposed to a single process at any one instant. However, the term multiprogramming is more appropriate to describe this concept, which is implemented mostly in software, whereas multiprocessing is more appropriate to describe the use of multiple hardware CPUs. A system can be both multiprocessing and multiprogramming, only one of the two, or neither of the two. Time-sharing refers to sharing a computing resource among many users by multitasking. Because early mainframes and minicomputers were extremely expensive, it was rarely possible to allow a single user exclusive access to the machine for interactive use. But because computers in interactive use often spend much of their time idly waiting for user input, it was suggested that multiple users could share a machine by using one user's idle time to service other users. Similarly, small slices of time spent waiting for disk, tape, or network input could be granted to other users. Computers capable of providing time-sharing services would often operate in batch mode overnight.
Multithreaded programming vs multiprocess?
Multitasking is a method for multiple tasks to share a single resource, like a CPU. This is usually accomplished in software via special programming.Multiprocessing is the use of multiple CPUs in the same computer and the method of splitting tasks between them. This is usually done with hardware on the motherboard.

What is multiprogramming directed by?
Multiprograming is way to run multi programs simultanteously.It give you feel that all your programs running simultaneously.For example windows is a multiprogramming environment in which you could run many programs simultaneously.Deep_viewActually,operating system create threads for each program you initiate.And according to prescribed algorithms,all threads get a prescribed time slot for each thread to executive.As the time slot is in millisecond user cant get the idea that one program stoped and anotherstart running.Turn by turnt
What is the difference between multiprocessor and multitasking?
multitasking infers the mechanism to run many processes simultaneously with user interaction. multithreading is a mechanism of running various threads under single process within its own space.
How can parallel processing be implemented in Python using a for loop?
Parallel processing in Python can be implemented using the multiprocessing module. By creating multiple processes within a for loop, each process can execute a task concurrently, allowing for parallel processing.
What is the difference between multitasking multiprogramming and multiprocessingΣυμβουλή Όταν?
I have both BSCS and MSCS, with 24 years in industry, and I have heard the use of these terms vary depending upon who is using them, but this is my view based on my experience.Multiprogramming is an old and arcane term, that was originally used to describe the earlier timesharing type of system where multiple jobs/Programs could be submitted to a computer system, and it should share its various resources between all of the jobs that were running. The jobs/programs were not decomposed beyond the job level, and this was the granularity of the CPU and resource sharing that occurred. It is true to say that multiprogramming is still supported today on modern computers because it is true that multiple jobs/programs are running at once. However, this is true of all computers now, and is not even a relevant consideration. What is relevant though is the level of sharing that has changed dramatically over the years.Now, the terms multitasking, multiprocessing and multithreading, mean the exact same thing in the general sense, and none has any dependency on the number of CPUs in a system. The first thing to understand here is that the words are basically synonymous in the general sense in that, a task is a process is a job is a thread is a program. Its all based on your POV. Where these terms start to take on specific meaning is when viewed in the context of a specific execution environment where a program is designed, compiled, loaded and executed on a specific piece of computer hardware. This context might assign a hierarchical meaning such as a program is the highest level of organization that decomposes into multiple tasks that run separately, that each can be decomposed into one or more processes, that can be further decomposed into some number of threads. Just an example.You can take that same decomposition and apply it in the compiler used to build software for a true multiprocessor system, and it will look for these, and also other patterns of execution that allow load balancing between the processors. Such tools will also usually allow for high level partitioning, but will also usually have automatic load balancing mechanisms in place that try to maximize CPU utilization. In the end, the multiprocessor system is executing the software in the same way on each processor, but can get real parallelism not found in a single processor system.The use of such terms is also influenced by how a program is designed because it can be designed to execute as single monolithic beast with a single execution path through it, or it can be specifically designed as a set of independent units that all get started by the program, and do all the work. Such units are called tasks, processes, functions, and even threads. One can enter into debates that a thread is really a light weight process, as opposed to a heavy weight process, but then one starts to get into the boring minutia of how processes are represented by the OS,etc, and this is always context specific, and not worth the time.All computers and operating systems in use today support very fine grained sharing of the CPU between multiple jobs, tasks, threads, processes, and some even analyze the code instructions at runtime to determine which blocks of instructions can be run out of order.in simple words multitasking/ multiprogramming conveys single processor and multiprocessing connotes to 2 processors being used to accomplish a task/job. A minor difference between multitasking and multiprogramming can be understood by help of threads in JAVA where each (more than 1 program) program being run attributes to multiprogramming and each thread within a program connotes to multitasking as they share time with and r run concurrently......For all the terminologies Multiprogramming is the core. Multiprogramming is the process of loading more than one program into the memory so that processor can be kept busy by switching between any of the loaded programs. Multitasking is derivation of multiprogramming where the operating system treats the programs loaded in the memory as task. But multiprocessing mainly deals with the hardware. Here more than one processing unit (CPU) comes into the picture. Multiprocessing leads to parallel computing. The difference of these three words/computer jargon is that: 1. Multitasking is the ability of a computer to handle a number of tasks or jobs simultaniously, while multiprogramming is the capacity to run or handle several programs at the same time. Lastly but not the least, multiprocessing is the ability or capacity of a computer to handle or rather solve a particular task in various ways. Hope you will make some sense out of this.Mutitasking and mutiprogramming are basically one and the same thing, in which the computer handles many tasks or programs simultniously. but multiprocessing is the techniuqe of handling one or more jobs in different ways, like in mutiprocessor architecture.Multi programing means executing more than one program ,but here when ever the processor is idle during execution of one process it go for execution of another program.Where as in Multitasking,this is a combination of both multi programing and time sharing.means in this it will execute more than one process simultaneously.The term Multitasking is used when more than one applications/programs/tasks are being run on a single processor. On the other hand, Multi-Processing is the ability to use more than one processor (CPU), on a single machine.
