11 A story about Bill & Paul Back in the early 1970’s, Bill and Paul were friends at Lakeside School in Seattle. They enjoyed working with computers and wrote many games they could play. The games were written in BASIC (Beginner’s All-Purpose Symbolic Instruction Code). In college, they improved their computer skills and sold their version of the BASIC language to other people on a cassette tape. They started making money selling BASIC and established a company called Microsoft! Bill is Bill Gates, a billionaire now running Microsoft.

14 Visual Basic.NET Class Objects 1. Language used to create windows and web application 2. Provide a Graphical User Interface or GUI (VS DOS) 3. A kind of 4GL (fourth-generation language) closer to human language. 4GL are designed to reduce programming effort, time to develop software and the cost of software development. E.g. VB, Oracle Reports, Oracle SQL*Plus, SQL 1. Language used to create windows and web application 2. Provide a Graphical User Interface or GUI (VS DOS) 3.
