Application programs - correct answer programs that people use to get their work done
Central processing unit (cpu) - correct answer a particular computer will have a
particular type of processor
Computer system - correct answer consists of hardware (physical parts of the
computer) and software (programs and data used with the physical computer)
Embedded system - correct answer a computer system that is part of a larger machine
and which controls how that machine operates
Input devices - correct answer keyboards, mouse, scanners, cameras, joysticks, and
microphones; a piece of equipment used to provide data and control signals to an
information processing system
Main memory - correct answer closely connected to the processor, stored data are
quickly and easily changed, holds the programs and data that the processor is actively
working with
Motherboard - correct answer components are connected to the main circuit board of
the computer
Network - correct answer consists of two or more computers connected so that they
can exchange data and programs
Operating system - correct answer responsible for starting up application programs,
running them, and managing the resources that they need
