Exam 19: broad concept of computer security and its importance in modern society.

Explain the concept of embedded systems and give examples from your own home.

Describe the three aspects of a system that make it well-suited for simulation.

How does an RGB value represent a color?

Why are spreadsheets particularly good at performing what-if analysis?

Describe the floating-point representation of a number.

Compare and contrast the ASCII character set and the Unicode character set.

Describe the steps in creating and running an assembly-language program.

Given non-negative integers A and B, their greatest common divisor is the largest integers that divides both A and B evenly, denoted gcd(A, B). Observe that for any A, gcd(A, 0) = A. Also, if A < B, then gcd(A, B) = gcd(A, B - A). Finally, for any A and B, gcd(A, B) = gcd(B, A). Use these three properties to develop an algorithm to compute greatest common divisors.

Explain the three primary ways that parallel-processing systems are used for more efficient problem solving.

Compare and contrast a stack and a queue from a logical view.

How does the process of sampling an audio signal result in a digitized representation of music that can be played back?
