Understanding binary encoding
Binary & ASCII
Computers store everything as binary (0s and 1s). The ASCII standard maps each letter, digit, and symbol to a number between 0 and 127. That number is stored as an 8-bit binary byte. For example, “Hello” becomes five bytes: 01001000 01100101 01101100 01101100 01101111.
Hexadecimal shorthand
Hexadecimal (base-16) is a compact way to write binary. Each hex digit represents exactly four bits, so one byte is always two hex digits. Programmers prefer hex because it is shorter than binary but maps directly to bits, making it easy to read memory addresses and colour codes.
Practical uses
Binary-to-text conversion is used in computer science education, debugging data transmissions, understanding file formats, and fun puzzles or escape rooms. Developers use it when inspecting network packets, binary files, or low-level protocol data.
