Input Device - answer- device used to insert data into a computer or other device (ex:
keyboard, mouse, microphone, scanner, voice recognition)
Output Device - answer- device that projects images, gives sound, and basically gives out
the info from the computer so the user can obtain it (ex: monitor, printer, projector, speakers)
Central Processing Unit (CPU) - answer- "Brain" of the computer that performs
instructions defined by software
Software - answer- Set of instructions that tells the hardware what to do. It is what guides
the hardware and tells it how to accomplish each task.
Operating System (OS) - answer- Software used to control the computer and its peripheral
equipment.

can understand.
, Hardware - answer- Physical elements of a computing systems (printer, circuit boards,
wires, keyboard, etc)
Machine Language - answer- Programs written in binary code
High-level language - answer- easier for humans to understand

Binary Number System - answer- Base2
Decimal Number System - answer- Base10
Octal Number System - answer- Base8
Hexadecimal Number System - answer- Base16
Hard Drive - answer- Storage device that stores digitally encoded data on rapidly rotating
rigid disks with magnetic surfaces. The device is either permanently installed within the
computer case or can be portable
Central Processing Unit (CPU) - answer- Brain of the computer that performs instructions
defined by software
Software - answer- Set of instructions that tells the hardware what to do. It is what guides
the hardware and tells it how to accomplish each task.
