Frequently Asked Questions

What is Hexadecimal used for?

Hexadecimal (Base 16) uses numbers 0-9 and letters A-F. It is widely used by programmers to represent web colors (e.g., #FFFFFF for white), memory addresses, and MAC addresses because it is shorter and more human-readable than long Binary strings.

Why does Binary only have 0 and 1?

Binary (Base 2) is the fundamental language of computers. A computer's processor consists of billions of microscopic switches that can only be in two states: ON (1) or OFF (0).

What is a Bitwise Operation?

Bitwise operations take two numbers, convert them to their Binary (0s and 1s) forms, and compare them bit-by-bit. For example, an "AND" operation checks if both bits are 1. This is heavily used in low-level programming, encryption, and network masking.
