Computer Science
A Brief Background
All the computer science information on this webpage was done through research on my part in order to study for the Illinois WYSE test, which is basically an academic test taken by several students....and one of the tests it includes is a computer science test.You may use this as a review for a beginner's level computer science class, if you're studying for a wyse test (or similar test), or if you just want to sharpen up on your computer science knowledge. I will tell you up front though...computer science is very different from practical computer knowledge. You won't learn how to do home networking...you'll learn about number theory and how the basic logical systems of a computer run. With that said, let's go ahead and get knee-deep into computer science.
Note: One last thing. If you'd like to take some WYSE tests, go to the WYSE link in the above paragraph, go to this link and download any of the pdf tests for the computer science test. At the very least you can use the tests to see how much this site has helped you.
Yet another note: I have never taken a computer science class. Any information I provide here is not guaranteed to be accurate -- so please realize I will make some mistakes.
Table of Contents
Binary NumbersEverything you ever wanted to know about binary numbers from negative binaries, to fractional binaries, to parity checks and more!
Octal and Hexidecimal
Learn what octal and hexidecimal number systems are and how to convert from binary to octal to hexidecimal and back.
Conditional Logic
The basics of using AND, OR, NOT, and XOR expressions to determine the value of logical expressions.
Sorting
There's many different ways to sort lists...learn what each method is and how it works.
Binary Trees
Figure out what traversing a binary tree means and learn to identify special types of trees.
Prefix, Infix, Postfix
There's more than one way to write A(B+C) -- learn the other two methods of writing out mathematical expressions.
