(22 cards)
What are the two main parts of a computer system?
Hardware and Software.
What do we call the physical parts of a computer that you can see and touch?
Hardware.
What’s the difference between external and internal hardware? Give an example of each.
External hardware is outside the computer (like a keyboard or mouse). Internal hardware is inside the main computer box (like the CPU or RAM).
Name the four main types (classifications) of hardware components based on their job.
Input, Processing, Output, and Storage devices.
What is the job of Input Devices?
To put information into the computer.
Which input device is used for typing letters and numbers?
Keyboard.
Which input device lets you point at and click things on the screen?
Mouse.
Which input device is used to record your voice?
Microphone.
Which input device copies pictures or papers into the computer?
Scanner.
What is the main ‘brain’ or Processing Device of the computer called?
CPU (Central Processing Unit).
What are the three parts of the CPU?
CU (Control Unit), ALU (Arithmetic and Logic Unit), and MU (Memory Unit).
Which part of the CPU manages all the other parts?
CU (Control Unit).
Which part of the CPU does math and makes decisions (like comparing things)?
ALU (Arithmetic and Logic Unit).
Which part of the CPU stores information that’s being worked on right now?
MU (Memory Unit).
What is the job of Output Devices?
To show or give you the results from the computer.
Which output device displays the computer’s work on a screen?
Monitor.
What do you call the output you see on the monitor screen?
Softcopy.
Which output device prints information onto paper?
Printer.
What do you call the printed paper output from a printer?
Hardcopy (or printout).
Which output devices let you hear sound from the computer?
Speakers or Headphones.
Which output device lets you listen to sound privately?
Headphones.
What is RAM like?
RAM is like the computer’s temporary workspace or desk. It holds the information the CPU is using right now so it can work quickly.
