Why do computers use binary?

Electronic circuits have two stable states (on/off, high/low voltage), making binary the natural representation. Complex data is encoded from these fundamental 1s and 0s.

What are hex color codes?

HTML/CSS colors like #1A2B3C use hex pairs for red (1A), green (2B), and blue (3C). Each pair ranges from 00 (0) to FF (255), giving 16.7 million possible colors.

A byte is 8 binary bits, representing values from 00000000 (0) to 11111111 (255 decimal, FF hex). A kilobyte is 1024 bytes.
