IPPJ- Review Lesson

Review 

All digital data is made up of layers of abstraction. The lowest is an individual 1 or 0 called a bit. Eight bits is called byte and creates a unique binary code that represents a letter, number, or symbol. Binary code is represented by base 2. Two types of programming languages are Low Level and High Level.  Low Level programming languages are closet to binary code. High Level programs are abstracted and need to be compiled or interpreted into binary code. Each language has its own syntax and library of classes, methods, and functions to use. Processing is a programming language using the Java syntax. It has many pre-defined functions for drawing that makes it easy to create graphical program for creative expression and enjoyment. Computer screens are made up of tiny dots called pixels that represent an R, G, B value representing a color. As you begin your code, you may encounter errors in your program. The three types of errors you may encounter are syntax, logical, and runtime.
