⩥ Operating system. Answer: Software that manages a computer's
hardware, helps applications work, and lets users interact with the
computer
⩥ hardware. Answer: The CPU, memory devices, input/output devices,
and any other physical components that are part of a computer
⩥ application program. Answer: a program designed for end-user
execution, such as a word processor, spreadsheet, compiler, or Web
browser
⩥ ease of use. Answer: the amount of difficulty and complexity involved
in using some aspect of computing
⩥ resource utilization. Answer: the amount of a given resource
(hardware or software) that is being used
,⩥ touch screen. Answer: a touch-sensitive screen used as a computer
input device
⩥ voice recognition. Answer: a computer interface based on spoken
commands, which the computer parses and turns into actions
⩥ Siri. Answer: the Apple voice-recognition system
⩥ embedded computer. Answer: 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. Answer: an operating system or application that
determines how resources are to be used
⩥ control program. Answer: 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. Answer: the idea that the number of parts on a computer
chip doubles about every 18 months
⩥ kernel. Answer: the main part of an operating system that starts
running as soon as a computer turns on
, ⩥ system program. Answer: software related to the operating system but
designed for smaller and more specific tasks
⩥ bus. Answer: a pathway that moves data and instructions between
parts of a computer, like the CPU and devices
⩥ device driver. Answer: software that helps the operating system talk to
and control hardware like printers or keyboards
⩥ interrupt. Answer: a signal from a device telling the computer's brain
(the CPU) that something important needs attention right away
⩥ interrupt vector. Answer: a list that shows where the computer should
go to handle different kinds of interruptions
⩥ interrupt-request line. Answer: a wire or circuit that lets devices send
signals to the CPU to ask for attention
⩥ interrupt-handler routine. Answer: a special program that the
computer runs when it gets an interrupt signal
⩥ interrupt-controller hardware. Answer: parts of the computer that
manage when and how interrupts are handled
