Frequently asked questions
A byte is 8 bits, and each ASCII character takes one byte.
How text becomes binary
Each character is first turned into UTF-8 bytes, and each byte is written as 8 binary digits (0s and 1s). The letter "A" is byte 65, written as 01000001 in binary.
This is how computers actually store text at the lowest level, and converting between the two forms is a common exercise for learning how encoding works.
