Question

Suppose three items R, S, and T are placed in a queue in that order. Then one item is removed from the queue before a fourth item, X is placed in the queue. Then one item is removed from the queue, the items Y and Z are placed in the queue, and then the queue is emptied by removing one item at a time. List all of the items in the order in which they were removed. What is the distinction between application software and system software? Give an example of each. Define the term 'process' as it is used in the context of operating systems. What is the difference between a process that is ready and a process that is waiting? List five resources to which a multitasking operating system might have to coordinate access. What is the similarity between deadlock and starvation? What is the difference between deadlock and starvation? What is the role of: The user interface of an operating system? The kernel of an operating system? Identify a situation in a multiprogramming system in which a process does not consume the entire time slice. What problem arises as the lengths of the time slices in a multiprogramming system are made shorter and shorter? What about as they become longer and longer? What is a multi-core operating system?

Explanation / Answer

1)Answer:

QUEUE MEAN FIFO= FIRST IN FIRST OUT.so list is

->R

->S

->T

->X

->Y

->Z

2)Answer:

the distinction between application software and system software:

Application software:

The Application software, is various programs that used to utilize the machine’s capabilities.Program for doing the accounting job for a company is different than the software that for doing thehuman resources job. There are a lot Applications software are available today and thedevelopment of such software will never stop because of the business demands.

The utilitysoftware is the software that extend or customize the capabilities of the operating system, usuallythese type of software performs fundamental tasks to the computer installations, but not includedin the operating system. Example for utility software, CD copying software, Multimedia player etc...

3)Answer:

In computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OS), aprocess may be made up of multiple threads of execution that execute instructions concurrently.

->A process is basically a program in execution. The execution of a process must progress in a sequential fashion.
