Codetext is a way for computers to understand and use words. Computers don't understand the same language that people use. Instead, they use a special language called codetext. Codetext is made up of a bunch of numbers and symbols that a computer can understand. It helps computers understand what commands we want them to do. For example, if you tell a computer to open a web page, it needs to know what web page to open and that information is written in codetext.
