Operating system concepts

Question

Multi processing OS is an OS with more than one processor it it right?? if its is it implies that throughput is better is these os ans more no. of process can be excecuted per unit time.

Answer 1

yes , right.

Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term Multi processing OS  refers to the ability of a OS to support more than one processor or the ability to allocate tasks between them.

yes throughput is better in case of Multiprocessor OS . Increasing throughput is one of the advantage to use multi-procesor OS.

The advantages of the multiprocessing system are:

1. Increased Throughput − By increasing the number of processors, more work can be completed in a unit time.

2. Cost Saving − Parallel system shares the memory, buses, peripherals etc. Multiprocessor system thus saves money as compared to multiple single systems. Also, if a number of programs are to operate on the same data, it is cheaper to store that data on one single disk and shared by all processors instead of using many copies of the same data.

3. Increased Reliability − In this system, as the workload is distributed among several processors which results in increased reliability. If one processor fails then its failure may slightly slow down the speed of the system but system will work smoothly.
