Stereo vs. Mono sound
Monophonic (mono) sound is a audio file that contains only a signal track that plays all the audio signals mixed together. Stereophonic (stereo) sound contains two audio tracks that creates an illusion of directionality and audible perspective.In other words it gives an immersive audio experience.

Moore's Law
Moore’s Law, developed by Gordon Moore the co-founder of Intel, states that the number of transistors on a computer microchip doubles about every two years. This process causes the size of computers to shrink exponentially. Experts believe that this growth will continue for the next few decades.
The computer industry uses this principle to plan for their future technological output.

ENIAC I
ENIAC (Electronic Numerical Integrator and Computer) is considered tp be the first fully functioned computer. It was capable of reprogramming itself to solve different types of computing problems. ENIAC was developed in 1946 by John Mauchly and John Presper Eckert to calculate artillery firing tables for the United States Army. The ENIAC contained 17,468 vacuum tubes, covered 1800 square feet, weighted 30 tons and used 160 kilowatts of electrical power.
The vacuum tubes were used for binary on and off determinations and have now been replaced by, solid-state devices such as transistors and semiconductors.

Binary Code
A Binary Code is the language that computers speak. It is a series of on/off determinations represented by the numbers 1 and 0. A single on/off determination is called a bit.
8 Bits make up a byte which is able to represent a single character on a computer screen (letter, number, etc..).
A thousand bytes is a kilobyte, and a thousand kilobytes is a megabyte. Continuing in this x1000 pattern with Gigabytes, Terabytes, Petabytes, and so on...
Here is a link that gives examples of how much information that these orders of magnitude of memory can store.

"This Sentence is Not True."
The first assingment for Mr. Teheran's class this year was to write a response to this statement: "This sentence is not true."
This assingment was not only designed to mess with our minds, but also to illustrate the concept of paradox.
Your response should be kept in your notebook/sketchpad.
