  1. Tutorial 1 Introduction to computers, the Internet & VB .Net

  2. What is a Computer? • Examples? • History • A device capable of • Performing computation • Making logical decisions • Faster than human • Process data using computer programs

  3. What is a computer program? • A set of instructions • a.k.a. application & software

  4. Computer Organization • Input devices: keyboard, mouse, scanner, microphone, digital camera, & etc. • Output devices: monitor, printer, projector, device control, & etc. • Memory: Primary memory, RAM. Voatile. • Arithmetic & logic unit (ALU): Performs calculation, logical comparison, decision making. Continue 

  5. Central processing unit (CPU): Administrates process operations. • Secondary storage: Long-term storage of applications and data. E.g. hard drive, CD/DVD drive , & etc.

  6. Three Types of Languages • Machine language: A natural language of a particular computer  machine dependent. +3422221207 +4060234234 +6345335372 Continue 

  7. Assembly language: English-like. Translator program called assembler converts to machine language. LOAD BASEPAY ADD OVERPAY STORE GROSSPAY • High-level language: More convenient for programmers. GrossPay = BasePay + OverPay

  8. High level languages • Visual Basic .Net: Evolved from Visual Basic. GUI. Object Oriented. • Pascal, C, C++, C# • COBOL • Java • HTML?, JavaScript?, VBScript?

  9. Language Relationships Refer to http://www.erg.abdn.ac.uk/users/gorry/eg2068/course/comp.html

  10. What is .Net • A set of software technologies for connecting information, people, systems, and devices. • Based on Web services—small building-block applications that can connect to each other as well as to other, larger applications over the Internet. http://www.microsoft.com/net/basics/ Continue 

  11. Object Oriented Programming • Example: What if the replicater does not use OOP? • Structure: • Object.Property or Object.Attribute • Object.Behavior or Object.Method • Class: Related objects. E.g. car, wheel, hub, bolt, & etc.
