Real Life Examples of Binary Code: Where Do We Use It?

📚 Quick Study Guide

• 🧮 Binary code is a base-2 numerical system that uses only two digits: 0 and 1.
• 💻 It's the fundamental language of computers because electronic circuits can easily represent 0 (off) and 1 (on).
• 💾 All data on your computer, from text to images to videos, is ultimately stored as binary.
• 📡 Binary is used in digital communication to transmit data reliably over networks.
• 🕹️ Modern electronics, including smartphones, gaming consoles, and smart appliances, rely on binary code for their operation.
