Announcements If you have not picked up a syllabus, please do so Assignment #1 – sign and return form on last page of syllabus

Last time Looked at encoding of information using bits Can encode numbers or words

Encoding machine instructions Use bits to encode those as well When we want the machine to follow those instructions: Fetch Decode Execute

Assembly language ADD r1 r2 STOR r2 r1 SUB r3 r1

High-level languages Step closer to natural language from machine language.

tools Editor Compiler Execution Environment Combined together in IDE’s (Integrated Development Environments) NetBeans, Jgrasp, Eclipse, DrJava

Programming a computer To program anything that is computable, programming languages must have the ability to perform the following three operations: Sequencing Selection Repetition

Our Language: Java High level programming language Object-oriented

Question Who has programmed before? What languages did you use?
