We communicate with numbers, images, and text. How does the computer represent this information? In this lab, you will learn about the basics of digitizing data for the computer.
Prerequisites
Before you take this lab, make sure you have already completed Big Picture of the Computing Machine. This is part 2 of Understanding How the Computer Works series.
What You Will Learn
In this lab, you will learn about data and information representations that the computer understands. These include:
- Numbering systems including Binary (you know those 1s and 0s that make up things like KB, MB, GB, TB, etc.)
- Hexadecimal (hum, you know what CSS hex colors use)
- Text representations with ASCII and Unicode
- How computers see images
This lab will turn on so many light bulbs for you. Finally, you will get to understand what the computer needs to process information and data.
You will grow in this profession when you incrementally and systematically stretch yourself....bit-by-bit.
