Frequently Asked Questions
What is hexadecimal?+
Hexadecimal (base 16) uses digits 0-9 and letters A-F. Each hex digit represents exactly 4 binary bits, making it a compact way to represent binary data. For example, binary 11111111 = hex FF = decimal 255.
Why do computers use binary?+
Digital circuits are built from transistors that have two states: on (1) and off (0). Binary naturally maps to these two electrical states. All higher-level data (text, images, programs) is ultimately encoded as sequences of 0s and 1s.
