  2. Why you are here? • Where will you go? • What is this course for?

  3. What Are Computers? • Computers are powerful tools for (generalized) computation • Numerical analysis, database, document processing, control, gaming, … • Computers are fast, precise, and highly flexible. • Complementary roles between man and machine • Human being: Thinking, innovating, … • Machine: Data processing, computation, …

  4. Computer Programming • What is programming? • Computers are quick, reliable, and flexible. • The flexibility of computers is a result of the idea "stored-program control". • We instruct computer to perform tasks via programming - the writing of computer control programs. • Windows programming is the writing of computer programs running within Windows environments.

  5. Computer Programming (cont) • Programming paradigms • Hardwired control, in contrast to flexible stored-program control • Machine code • Assembly language • High-level language • Macro of packages, extensions to designed functionality to fit customer's need • Script of operating systems, such as batch files, shell script, ... • Script of virtual machines, such as Netscape Navigator and Microsoft Internet Explorer are virtual machine for JavaScript.

  6. High-level Language Machine independent (portable) High productivity Assembly Language one instruction to one machine code Assembler Compiler Symbolic version of machine code Machine dependent Direct, low-level hardware control one statement to many machine codes Machine Code Machine Dependent Executable
