8.11.1 Digital Information Cheat Sheet
- Binary Basics - Computers speak in 0s and 1s using the binary system to store everything from numbers and text to images and sounds. Think of each bit as a tiny light switch that's either off (0) or on (1). For example, the number 5 magically becomes 101 in binary. Intel: Digital Information
- Character Encoding - To turn letters into those 0s and 1s, machines follow encoding rules like ASCII and Unicode. In ASCII, the capital "A" lights up as 01000001, giving every character its own secret binary code. Unicode expands this magic so you can display emojis, symbols, and scripts from around the world! Intel: Character Encoding
- Pixels & Images - Digital pictures are just grids of pixels, each made of red, green, and blue sub‑pixels blending to create colors. The more pixels you have, the sharper and more detailed your photo looks. It's like zooming into a mosaic made of tiny colored tiles! Intel: Digital Imagery
- Decimal to Binary - Converting decimals to binary is a fun puzzle: subtract the largest power of two you can until you hit zero, marking a "1" for each used power and "0" for each skipped one. So decimal 5 subtracts 4 (2²) then 1 (2❰), giving you 101. It's like packing a backpack with powers of two! Intel: Number Conversion
- Binary Addition - Adding in binary is similar to decimal math, but you carry over when your column sums to 2 (10₂). For example, 10₂ + 11₂ equals 101₂ after carrying that extra bit. It's a great brain‑teaser that sharpens your logic skills! Intel: Binary Arithmetic
- Easy Duplication - Digital files can be copied in a flash and shared endlessly without losing quality. This makes spreading memes easy but also means controlling once‑shared info is tricky. Always think twice before hitting "share"! NZ Digital Tech Guide
- Data Persistence - Once digital data is out there, it's tough to completely delete - copies can hide on servers, backups, or old devices. Even if you hit "delete," someone might still have a snapshot. It's like trying to un‑pop a bubble! NZ Data Persistence
- Remote Access - The internet allows data to be edited, moved, or erased from anywhere in the world - welcome to remote control for files! This superpower calls for strong passwords and safe networks to keep prying eyes out. Stay secure or risk a digital surprise! NZ Remote Access
- Logic Gates - Computers make decisions with logic gates like AND and OR, which check if one or both conditions are true. AND is strict - it needs both inputs "on" to light up. OR is more lenient - one "on" input is enough to pass the test. Intel: Logic Gates
- Digital Literacy - Mastering keyboarding, understanding hardware basics, and using productivity tools are the building blocks of modern learning. These skills help you research, collaborate, and create like a digital pro. Level up your tech game and watch doors open! Learning.com: Digital Skills
