Program
All computers are powered by electricity. They must run on electricity in one form or another, which means that they are exclusively a product of the Twentieth Century.
Computer
Data Storage
Electronic
Program
A computer must be able to store information (like programs and data) to be used at another time. This computer feature turns the machine into an electronic filing cabinet.

Program
Storage
A computer must be able to follow a set of instructions (called programs) to operate.

Storage
On top of being able to store information, a computer must be able to retrieve the information that it has stored. Storing is meaningless without the capability to retrieve.

Storage
This is the operation of manipulating and transforming data into something useful. A program , which is a set of written instructions, is what tells the computer how to manipulate and transform the data it was given into information.
