• 🧮 Each digit in binary is called a bit.
• 🔁 Binary can represent numbers, letters, and instructions.
• ➕ Decimal numbers can be converted to binary, and vice versa.
• 💻 Computers use binary because it's easy to represent with electrical signals (on/off).
• 💡 Every piece of data on a computer, from text to images, is ultimately stored as binary.
• 🔑 Understanding binary is fundamental to understanding how computers work.
