Explain bounded buffer and unbounded buffer.
Here in a producer-consumer problem the producer process produces information that is consumed by a consumer process. At this time a buffer is used and that buffer is filled by the producer and emptied by the consumer.
A buffer maybe bounded or unbounded
Unbounded buffer: The consumer may have to wait for new items however the producer can always produce new items an unbounded buffer places no practical limit on the size of the buffer.
Bounded buffer: A bounded buffer supposed that there is a fixed buffer size. In this case the consumer should wait if the buffer is empty and the producer must wait if the buffer is full.
What is reference string We evaluate an algorithm by running it on a definite string of memory reference and computing the number of page faults. The string of memory reference
Assume there are only 4 page frames in the physical memory, for the following reference string: 1, 2, 3, 4, 5, 3, 4, 1, 6, 7, 8, 7, 8, 9, 7, 8, 9, 5, 4, 5, 4, 2, 8. a) What i
Define UFD and MFD. In the two-level directory structure, every user has her own user file directory (UFD). Every UFD has a similar structure, but lists only the files of a one
Contiguous allocation The contiguous-allocation method needs each file to occupy a set of contiguous blocks of the disk. Disk addresses explain a linear ordering on the disk. T

Q. What is Multiprogramming? Multiprogramming When two or more programs are in memory at the same instance, sharing the processor is referred to multiprogramming opera
Utility Programs: those programs which are not the essential part of operating system. But they provide different utilities / features to the users e.g. MS-DOS : Fdisk, FORMAT, AT
when demand is 24000 units/year, production rate is 48000 units/year, setup cost is rs 200 per setup, carring cost is rs 20 per units/year, and economic batch quantity is 692.8203
What advantages are there to this two-level directory? Users are isolated from each other. Users have more freedom in choosing file names.
In a p system each part (RAM, ROM, I/O) has a unique set of numbers. The allocation of these numbers is usually stated in the form of a memory map. This is a plot of data bus agai
