From Characters to Code: How Computers Understand Text 💻

At their core, computers only understand one thing: electricity being on or off. We represent these two states with the numbers 1 (on) and 0 (off). This is the binary system. But how does a computer take something complex like the letter "A" or the symbol "$" and turn it into a series of ones and zeros? The answer lies in character encoding.

Character Encoding: The Rosetta Stone of Computing

A character encoding system is a standard that assigns a unique number to every character. The most famous early standard is ASCII (American Standard Code for Information Interchange). In ASCII, for example, the uppercase letter "A" is assigned the number 65, "B" is 66, and so on. A lowercase "a" is 97.

This converter takes each character from your text, finds its corresponding numeric value (its "character code"), and then converts that number into its 8-bit binary equivalent.

How the Conversion Works

Let's take the word "Hi" as an example:

  1. The tool looks at the first character, "H". Its ASCII code is 72.
  2. It then converts the decimal number 72 into an 8-bit binary number, which is 01001000.
  3. Next, it looks at the character "i". Its ASCII code is 105.
  4. It converts 105 into its 8-bit binary form, which is 01101001.

The final output is these two binary numbers joined together: 01001000 01101001. This is exactly how a computer stores the text "Hi" in its memory or on a disk. This tool lets you peek behind the curtain and see the fundamental language of computers in action.
