    1. ISM 2110 Programming for Business Applications Lecture 1 - Introduction to Computer and Delphi By Tony Chun-Kuen WONG

    2. Objectives of this subject Learn a disciplined approach to write programs that are Clear, Correct and Easy to Modify Learn how to solve business problems Tool : Delphi 6 Programming Language : Object Pascal a tool to facilitate our learning, once you learn about the discipline to write a program, you can use any language to write your applications.

    3. Delphi 6 An integrated development environment (IDE) Object Pascal Language Compiler Visual Development Environment Database Tools Visual Component Library It is designed for Rapid Application Development (RAD)

    4. What happen in the real world !!!

    5. Introduction to Computer Hardware (Figure 1.9) Central Processing Unit (CPU) Display Device Input Devices Output Devices Memory (ROM, RAM) Storage Devices Software System Software Application Software General-purpose software Application-specific software

    6. Computing environment Time-Sharing environment Client-Server environment Binary Number System Computers understand only the base 2, or binary number system Mathematical operations performed in computers are subject to round-off errors

    7. 1001 1100 It is an binary number Each 0 and 1 in this number is called a bit Computer group and store information in series of eight bits, with each series called a byte Kilobyte (KB) 210 Megabyte (MB) 220 Gigabyte (GB) 230

    8. Computer Languages 1940s machine Language 1950s Symbolic languages Assembly (converted to machine language by assembler) 1960s High-Level languages Basic, Fortran, Cobol, Pascal, C (converted to machine language by complier or an interpreter) 1990s Natural languages (evolving) The ONLY language understood by a computer is machine language

    9. Turn Object Pascal to Machine Code Writing and editing Programs Compiling Programs Linking Programs Program Execution

    10. What is Delphi ? Delphi is Borland's best-selling rapid application development (RAD) product for writing Windows applications. You can create Win32 console applications or Win32 graphical user interface (GUI) programs.

    11. Delphi integrated development environment (IDE)
