Answer the following questions using information from technology education websites or other online resources. Make certain that all information is in your own words. No credit can be given for information that is identical to that of another student or a web page.
1889: Herman Hollerith patented the Electric Tabulating Machine in 1889. This machine was basically used for
accounting purposes; storing numbers and such.
1944: Grace Hopper and Howard Aiken developed MARK I of the MARK series of computers in 1944 at
Harvard University. It was used by the U.S. Navy for calculations and weighed over 5 tons. Tons of data
was able to be stored in this machine. It also carried out simple math equations and logarithms.
1962: Steve Russell & MIT designed the first computer game ever. This game was created using a DEC digital
1964: Douglas Engelbart is the inventor of the infamous computer mouse! (Nicknamed that way because of the cord coming out of the back that looked like a tail.) The mouse is a device used by the computer user to control input into the computer.
Vacuum Tubes were used as signal amplifies in these first generation computers
The transistor is the main invention for this generation of computers. The transistor functions as a signal amplifier by working with and resisting 2-3 layers
Invented by Jack Kilby in 1958, integrated Circuits or the IC-chip were what stood out in the third generations computers. Also, there was an advance in the computer's memory and its ability to open more than 1 application
Very Large scale and Ultra Large scale IC-chips were introduced. Millions of information could fit onto these chips and saved power as well as reliability
Fifth generation computer will work with and take commands from voice authority. Also, this computers will work with artificial intelligence. Parallel processing will soon be more powerful than central processing
Teachers should be conversant with computer terminology and concepts that pertain to the use of technology in their classrooms.
The market for personal computers is very competitive, and manufacturers are continually working to develop better and more powerful systems. Unfortunately, you can not determine how powerful a computer is by looking at the outside. It is necessary to look at the system profile to determine the type of processor, memory, hard drive capacity, etc. Compare the system profile of the computer used in class with your computer at home on the following properties. You may want to refer to eHow or your OS Help menu to determine how to find this information on your computer.

How do filters work? Filters work by either "white listing" or "black listing" certain websites.
The authority (School, Parents, etc) can choose which websites are black listed and which ones are white listed.
Key words can also be filtered if a students tries to search something inappropriate.
