ITS-235 Quiz 1
batch and interactive
A hybrid system is a combination of ____ systems.
kernel
A(n)___________ is best defined as the primary part of the operating system that remains in random access memory (RAM) and is charged with performing the system's most essential tasks, such as managing main memory and disk access.
True
An important function of the Processor Manager is to keep track of the status of each job, process, and thread. True/False
False
Batch systems date from early computers, when each job consisted of a stack of chips entered into the system as a unit known as a stack. True/False
time slicing
In active multiprogramming, each program is allowed to use only a preset amount of CPU time before it is interrupted so another job can begin its execution. The interrupted job resumes execution at some later time. This idea is called ____.
True
In the 1980s, as a result of multiprocessing techniques, it became possible to execute two programs at the same time in parallel. True/False
True
In the 2010s, chips with millions of transistors that were very close together helped increase system performance dramatically. True/False
control unit
Starting in the 1950s, to reduce the discrepancy in speed between the I/O and the CPU, an interface called the ____ was placed between them to act as a buffer.
True
The Device Manager is responsible for connecting with every device that's available on the system and for choosing the most efficient way to allocate them. True/False
False
The Memory Manager is in charge of main memory, widely known as ROM. True/False
User Interface
The ____ is often very different from one operating system to the next, sometimes even between different versions of the same operating system.
True
The central processing unit (CPU) is the brains of the computer with the circuitry to control the interpretation and execution of instructions. True/False
False
The content of a random access memory (RAM) chip is nonvolatile, meaning that it is not erased when the power is turned off. True/False
True
The first bug was a moth trapped in a Harvard computer. True/False
kernel
The name for the core portion of an operating system is the ____.
firmware
The term ____ is used to describe the programming code that is used to start the computer and perform other necessary tasks.
True
There are two primary types of user interfaces: the graphical user interface and the command line interface. True/False
distributed
With ____ operating systems, users can think they are working with a system using one processor, when in fact they are connected to a cluster of many processors working closely together.
Virtualization
____ allows separate partitions of a single server to support a different operating system.
Cloud computing
____ is the practice of using Internet-connected resources to perform processing, storage, or other operations.
Main memory
____ is where the data and instructions of a computer must reside to be processed.
Virtual
____ memory was developed in the late 1970s and allowed portions of multiple programs to reside in memory at the same time.
Embedded
____ systems are computers that are physically placed inside the products in which they operate to add very specific features and capabilities.
Real-time
____ systems are used in time critical environments where reliability is key and data must be processed within a strict time limit.
Cloud
_____________ computing is the practice of using Internet-connected resources to perform processing, storage, or other operations.
