A section of a program that should be executed by at most one process at a time is called a

Which of the following is not involved in a context switch?

Which of the following is a technique for controlling access to a critical region?

Which of the following is not an attempt to provide security?

Describe a scenario that leads to deadlock in a computer system.

Multitasking in a computer with only one CPU is accomplished by a technique called

What are privileged instructions?

A ______________ is a set of instructions. In contrast, a ________________ is the activity of executing those instructions.

Describe concerns that occur when designing a time-sharing/multitasking operating system that do not occur in the case of a single tasking system.

Explain why the average length of a time slice would be reduced if the processes in an operating system's process table perform lots of I/O operations.

The end of a time slice is indicted by the occurrence of a signal called

In contrast to early batch processing techniques, ____________________ allows the user to communicate with the computer while the user's application is being executed. In turn, this type of processing requires that the computer's responses to its environment be performed in a timely manner, a requirement known as _______________________ .

What conditions are necessary for deadlock to occur?

What problem could occur if, to allow more processes to share time in a multiprogramming environment, an operating system is designed to use very short time slices? ________________________________________________________________________

Which of the following components of an operating system is executed as the result of an interrupt signal?

Which of the following items of information would not be contained in an operating system's process table?

Which of the following would not require real-time processing?

Explain the difference between application software and system software.
