Encode

Encode means to change something into a programming code. For instance, changing a letter into the binary code for that letter or changing an analog sound into a digital file. A good example of where you are most likely to encounter encoding is what happens in your browser. The URL (uniform resource locator) only supports so many characters, any other characters such as a space must be encoded to be understood. For example, if we wanted to have "computer hope" in the URL with the space it would be encoded to "computer%20hope".
