Exam 2: Operating System Overview

Security and protection as it relates to operating systems is grouped into four categories: Availability, Data integrity, Authenticity, and __________ .

The earliest computers employed __________ processing, a name derived by the way the users have access to the systems.

The processor itself is not a resource so the OS is not involved in determining how much of the processor time is devoted to the execution of a user program.

A special type of programming language used to provide instructions to the monitor is __________ .

The OS has five principal storage management responsibilities: process isolation, automatic allocation and management, support of modular programming, protection and access control, and __________ .

__________ is where the OS must prevent independent processes from interfering with each other's memory, both data and instructions.

A __________ is set at the beginning of each job to prevent any single job from monopolizing the system.

One of the first time-sharing operating systems to be developed was the __________ .

The phrase "control is passed to a job" means that the processor is now fetching and executing instructions from the monitor program.

The principal objective of __________ is to maximize processor use.

The __________ is the interface that is the boundary between hardware and software.

A process consists of three components: an executable program, the associated data needed by the program, and the execution context of the program.

The ABI gives a program access to the hardware resources and services available in a system through the user ISA.

The principle objective of Batch Multiprogramming is to minimize response time.

The key to the success of Linux has been its character as a free software package available under the auspice of the ___________ .

Multiprogramming operating systems are fairly sophisticated compared to single-program or _________ systems.

__________ was designed to keep the processor and I/O devices, including storage devices, simultaneously busy to achieve maximum efficiency.

In a time sharing system, a user's program is preempted at regular intervals, but due to relatively slow human reaction time this occurrence is usually transparent to the user.

The operating system's __________ refers to its inherent flexibility in permitting functional modifications to the system without interfering with service.

Virtualization technology enables a single PC or server to simultaneously run multiple operating systems or multiple sessions of a single OS.
