1980
– Tim Bereners-Lee developed a prototype hypertext system for researchers to use to share documents. 1989 – Berners-Lee and Robert Cailliau submitted separate proposal for an Internet-based hypertext based system. 1990 – Berners-Lee and Cailliau collaborated on a joint proposal, W3 project accepted by CERN. 1991 – HTML tags first publicly available 1995 – “HTML 2.0” completed, intended to serve as a standard. 1999- HTML 4.01 the last HTML specification published by W3C |
HyperText
Markup Language Ordinary text that uses tags to Markup the text that tells a browser how to display the text. A simple/flexible text editor can create a HTML page. Easy to use and lenient requirements. |

Extensible
Markup Language Allows the sharing of structured data across different information systems. Allows users to define their own tags More restrictive in its structure. Tags must be written the same way paying attention to quotations, upper and lower case letters. |

Advantages |
Disadvantages |
| Compiled: Fortran Pascal Java Visual Basic |
Faster
execution and deployment since the code is complied Takes up less memory User security and privacy are more protected. Gives author the ability to be more complex with what it is asking the page to do. |
Takes
much longer to develop and is more complex to learn how to write the code. |
| Scripting
: Java Script AppleScript CShell Python |
Easy
to author since is uses basic text. |
Takes
up more memory Takes longer to deploy since the text needs to be translated There are some issues with user security and privacy Limited to what it is capable of doing |
