What are Computers? Keyboard Mouse Monitor CPU Speakers Microphones RAM/ROM Hard Drive

Types of Computer Parts Input Storage Processing Output

Input Is what goes into a computer before anything else happens E.g., keyboard, mouse, microphone

Storage Is where information or data stores before it is processed Note: Information or data from the input cannot process instantly E.g., RAM, ROM, hard drive

Processing Calculates or processes the information or data obtained from the input E.g., CPU (Central Processing Unit)

Output Something that comes out after the processing Usually the end result that you want E.g., Monitor, speakers

Computers are … Systems that take some input (or store it), process it, and produce outputs  IPO E.g., personal computers (PCs), cell phones, humans (why ???)
