Week 1-2: Introduction to Computer and Computer Applications

A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware.

In other words, mass communication. Via the internet, computers spread content created on the computer (words or graphics) to the world at large. In other words, computers are a tool for mass communication.
