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: ASCII

ASCII (American Standard Code for Information Interchange) is a character encoding standard for electronic communication. It assigns a unique numeric code to each letter, number, and symbol. 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 ASCII numeric value, 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, often with a space for readability: 01001000 01101001. This is exactly how a computer stores the text "Hi" in its memory or on a disk. This tool lets you see the fundamental language of computers in action.
