Program
Computer
Application
The operating system's _______ refers to its inherent flexibility in permitting fun

DML
SML
Hardware features desirable in a batch-processing operating system include memory protection, timer, privileged instructions, and _______.
Clock cycles
Associated data
Interrupts
Kernels
A user program executes in a _______, in which certain areas of memory are protected from the user's use, and in which certain instructions may not be executed.
Kernel mode
User mode
Task mode
Batch mode
Multiprogramming operating systems are fairly sophisticated compared to single-program or _______ systems.
Uniprogramming
Time-sharing
Multitasking
Memory management
One of the first time-sharing operating systems to be developed was the _______.
Compatible Time-Sharing System
Real Time Transaction System
Multiple-Access System
Multiprogramming Operation System
The technique where a system clock generates interrupts, and at each clock interrupt the OS regains control and assigns the processor to another user, is
Time slicing
Multithreading
Round robin
Clock cycle
The _______ is the internal data by which the OS is able to supervise and control the process.
Executable program
Associated data
Nucleus
Execution context
_______ is concerned with the proper verification of the identity of users and the validity of messages or data.
Availability
Confidentiality
Authenticity
Data integrity
_______ is where the OS must prevent independent processes from interfering with each other's memory, both data and instructions.
Support of modular programming
Process isolation
Automatic allocation and management
Protection and access control
A common strategy to give each process in the queue some time in turn is referred to as a _______ technique.
Multithreading
Round-robin
Time slicing
Serial processing
The key to the success of Linux has been its character as a free software package available under the auspice of the _______.
World Wide Web Consortium
Free Software Foundation
Berkeley Software Distribution
GNU Public License
An OS should be constructed in such a way as to permit the effective development, testing, and introduction of new system fun
True
False
The OS masks the details of the hardware from the programmer and provides the programmer with a convenient interface for using the system.
True
False
The ABI gives a program access to the hardware resources and services available in a system through the user ISA.
True
False
The OS frequently relinquishes control and must depend on the processor to allow it to regain control.
True
False
One of the driving forces in operating system evolution is advancement in the underlying hardware technology.
True
False
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
True
False
A process consists of three components: an executable program, the associated data needed by the program, and the execution context of the program.
True
False
Uniprogramming typically provides better utilization of system resources than multiprogramming.
True
False
A monolithic kernel is implemented as a single process with all elements sharing the same address space.
True
False
The user has direct access to the processor with a batch-processing type of OS.
True
False
Both batch processing and time-sharing use multiprogramming.
True
False
The phrase "control is passed to a job" means that the processor is now fetching and executing instructions from the monitor program.
True
False
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.
True
False
The principle objective of Batch Multiprogramming is to minimize response time.
True
False
Virtualization technology enables a single PC or server to simultaneously run multiple operating systems or multiple sessions of a single OS.
True
False
