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.

Explain the Types of System Calls The major types of system calls are like this: a. Process Control: These types of system calls are employed to control the processes.
Allocators can also be used to avoid problems with unsafe languages. C and C++ are pervasive, with huge amounts of existing code. They are also memory-unsafe languages, in that the
