Question 1

How is text converted to binary?

Accepted Answer

Each character is first converted to its ASCII or Unicode code point (a number), then that number is expressed in base-2 (binary). For example, 'A' is ASCII 65, which is 01000001 in 8-bit binary. Each byte is typically represented as 8 binary digits.

Question 2

What encoding does this tool use?

Accepted Answer

This tool uses UTF-8 encoding, which is the web standard. ASCII characters (0–127) produce the same binary as plain ASCII. Multi-byte characters (accented letters, CJK characters, emoji) produce multiple binary groups.

Question 3

What is binary used for in computing?

Accepted Answer

Binary (base-2) is the native language of digital computers because electronic circuits naturally represent two states: on (1) and off (0). All data — text, images, audio, programs — is ultimately stored and processed as binary sequences at the hardware level.
