What is Input?
May get data from user to accept new data from software
What is Processing?
Performance of math operations from data
What is the process of Output?
Processed data delivered to software that requested it; in turn it delivers output to user
What is storage?
The mechanism that allows computers to maintain data for later
What 2 ways computers can store data?

Unicode
Modern method of representing characters. It assigns a code print , which is a number, to each character
