D686 Operating Systems Questions with 100%
Correct Answers
Operating system
A program that manages a computer's hardware, provides a basis for application programs,
and acts as an intermediary between the computer user and the computer hardware
Operating system
Software that manages a computer's hardware, helps applications work, and lets users interact
with the computer
hardware
The CPU, memory devices, input/output devices, and any other physical components that are
part of a computer
application program
a program designed for end-user execution, such as a word processor, spreadsheet, compiler,
or Web browser
ease of use
the amount of difficulty and complexity involved in using some aspect of computing
resource utilization
the amount of a given resource (hardware or software) that is being used
touch screen
a touch-sensitive screen used as a computer input device
voice recognition
,a computer interface based on spoken commands, which the computer parses and turns into
actions
Siri
the Apple voice-recognition system
embedded computer
a computer system within some other, large system (such as a car) that performs specific,
limited functions and has little or no user interface
resource allocator
an operating system or application that determines how resources are to be used
control program
a program that manages the execution of user programs to prevent errors and improper use of
the computer. it is especially concerned with the operation and control of I/O devices
Moore's law
the idea that the number of parts on a computer chip doubles about every 18 months
kernel
the main part of an operating system that starts running as soon as a computer turns on
system program
software related to the operating system but designed for smaller and more specific tasks
bus
a pathway that moves data and instructions between parts of a computer, like the CPU and
devices
, device driver
software that helps the operating system talk to and control hardware like printers or
keyboards
interrupt
a signal from a device telling the computer's brain (the CPU) that something important needs
attention right away
interrupt vector
a list that shows where the computer should go to handle different kinds of interruptions
interrupt-request line
a wire or circuit that lets devices send signals to the CPU to ask for attention
interrupt-handler routine
a special program that the computer runs when it gets an interrupt signal
interrupt-controller hardware
parts of the computer that manage when and how interrupts are handled
nonmaskable interrupt
an urgent signal that the CPU must deal with immediately, like a major error
maskable
describes an interrupt that the CPU can choose to ignore briefly, usually when it's busy doing
something very important
interrupt chaining
