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.
Problem: (a) Modern operating systems are interrupt driven. If there are no processes to execute, no I/O devices to service, and no users to whom to respond, an operating syste
How do we keep track of where the free pieces of memory are? One idea is to maintain a set of linked-lists of free space; each linked-list will store free chunks of some given size
Suppose we want to program a Web server; we could easily do so without using concurrency, as follows: while(true) wait connection read from socket and parse url look up url cont
