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
1.increase throughput 2.Economy of scale 3. Increased reliability
Multiprocessor systems have gained popularity over the years as they allow the user to do more than they could with a single processor system. Xbox 360, CELL, and Sequent are examples of multiprocessor systems.
In the context of operating system build types, "multiprocessor free" refers to an operating system build that does not support multiprocessor systems. This means it is designed to run on single-processor systems only. On the other hand, "multiprocessor kernel" refers to an operating system build that supports multiprocessor systems, allowing for parallel processing and improved performance by utilizing multiple processors simultaneously. The inclusion of a multiprocessor kernel enables the operating system to take advantage of the capabilities offered by multiprocessor hardware configurations.
Multiprocessor Operating Systems
In multiprocessor systems, failure of one processor will not halt the system, but only slow it down by sharing the work of failure system by other systems. This ability to continue providing service is proportional to the surviving hardware is called graceful degradation.

multiprocessor and multicomputer
Advantages include: increase throughput, economy of scale and increased reliability. Multiprocessing is the use of two or more central processing units within a single computer system.
is a number of linked systems, working together closely ,so that they form a single computer
for improving the efficiency of the computer system.In multiprocessor environment , instructions can be executed parallely.
