Q. Explain the Concept of Process?
A process is sequential program in execution. A process states the basic unit of computation for the computer. Components of process are:
1. Object Program
2. Data
3. Resources
4. Status of the process execution.
Object program i.e. code to be executed. Data is used for executing the program. While executing the program it may need some resources. Last component is used for verifying the status of process execution. A process can run to completion only when all requested resources have been allocated to the process. two or more processes can be executing the same program, each using their own resources and data.
How can the deadlock be prevented Bankers algorithm : The Resource allocation graph algorithm isn't applicable to a resource allocation system with multiple instances of every
Deadlocks can be detected while the program is running, by running cycle detection algorithms on the graph that de?nes the current use of resources. De?ne this graph as follows:

How can the index blocks be implemented in the indexed allocation scheme? The index block can be implemented as follows a. Multilevel scheme b. Linked scheme c. Combin
For example, by initializing a semaphore to 0, threads can wait for an event to occur, and impose an ordering constraint, similar to a monitor using condition variables, but with m
Developing Code with Threads Writing code to support a thread-based implementation is very straightforward. Simple APIs are presented to the developer for each threads package.

Define swapping. A process requires being in memory to be executed. Though a process can be swapped temporarily out of memory to a backing store and then brought back into memo
