OBJECTIVES: I will learn about the evolution of computer storage and processing power during today's class.

WORDS FOR TODAY:

• Hard Drives: Data is stored magnetically on a spinning platter and stored as a series of 0's and 1's. Operates at millisecond time scales (10^-3 second)
• RAM: Random Access Memory. Used for processing information. Operates at nanosecond (10^-9 second) time scales.
• ROM: Read Only Memory. Used by manufacturers to store critical processing information at a specific, addressable place. Data on the ROM chip cannot be erased, modified or otherwise changed.
• PROM: Programmable Read-Only Memory. Created empty by manufacturers in bulk and sold to companies. Those companies then "burn in" information on the chip that cannot be changed thereafter.
• EPROM: Erasable Programmable Read-Only Memory. Existing data on the chip can be erased with a burst of UV light.
• EEPROM: Electronically Erasable Programmable Read-Only Memory. Existing data on the chip can be erased using specifically timed pulses of electricity.
• Big Data - a broad term for data sets so large or complex that traditional data processing applications are inadequate.
• Moore's Law - a predication made by Gordon Moore in 1965 that computing power will double every 1.5-2 years, it has remained more or less true ever since.
• Original computers (1950's - 1970's): Room Sized computing devices the size of a small room that required strict environmental controls
• Mini-Computers (1970's - present): Scaled-down computers that were the size of a BIG desk. Accessed through "dumb" terminals
• Micro-Computers: (1980 - present) Computers that sit on top of our desks
• SuperComputers (1970's - present). High powered, high speed machines used for weather forecasting and nuclear bomb simulations. Typically used by large universities and governments. They have been and remain VERY expensive.

WORK O' THE DAY: 

Let's *quickly* review all that RAM/ROM stuff from yesterday.

By the by, how RAM similar to ROM? How is it different?

Also, how are RAM/ROM similar to data storage? How are they different?

═══════════════════════════

Now back to the good stuff!

Let's have the folk designated by the color BLUE be our Project Managers today. That means only the folks designated by the color BLUE can initiate conversation-- please keep that in mind!

PM folks-- please create a Google Slide and share it with your team.

Do a wee bit of research on your team's storage type and have each person contribute a coupla slides overall. Please-- bullet points only, no walls of text (ever!) PICTURES/CHARTS & GRAPHICS ARE ALWAYS HELPFUL!!

Your goal is for all of your slides to combine to make a convincing argument that your tech is truly impressive/amazing/game changing etc...

Tomorrow I'll spin the wheel of fate and have one person from each group stand and present your arguments to me. I'll also question the team!
