D)

Java

Correct Answer : Java

The computer does not read the information the same way we do. Instead of understanding the symbols we are used to, computers read numbers and letters using a special code of 1's and 0's. Each letter takes a specific combination of around eight 1's and 0's to make. In order for us to create data on computers, whether it be software or a web-page, we have developed a type of computer language called HTML. HTML, a mix between the computer's language and our own, gives us a way to easily communicate with computers. HTML has made many advancements, from basic HTML to XML, Java, and finally javascript.
