Standard 3: A. Search for information using internet, CD-ROM, database or library. 1. Research is the process of collecting data nad information. B. Multimedia Technology 1. Combining technologies together. a. video, pictures, garageband, powerpoint. b. your portfolio is multimedia technology. c. A meeting combining telephones, television and computers. C. Computer Terms 1. Digital storage for a computer is compressed in bytes. a. Bytes. Kilobytes (1000) ((1024)). Megabyte (million). Gigabyte (billion). Terabyte (trillion). 2. Computer Processing Speed are expressed in computer or central processing units. (CPU's) Computer - Faster or slower. 3. Local area network (LAN) Is our classroom- has own server, shared hardware, can communicate with each other. 4. Random access memory- RAM temporary memory. 5. Read only memory- ROM- Permenant memory in a bomputer, including the computer's operating system. 6. Digital is the process of turning a signal into binary codes ( 1's and 0's) it stores tons of information. 7. Analog is the process of taking and audio or video signal and translating it into electronic pulses. 8. Computer numerial control- CNC computers that can take control and makes things.

Standard 4: A. Orthographic projection- a way to represent a 3-d object in 2d. It shows several views( 3- dimensional) B. Graphs visually shows informatiojn, data or comparisons. C. Sequence diagram, shows the order or steps/ sequence.

Standard 5: A. Integrated circuits- contains thousands of components. 1. Circuit braker- protects houses, schools, and all buildings with electricity from an overload. 2.Conducters carry electricity. B. Reciprocating motion: is a back and forth or an up and down motion which repeats over and over again. C. Rotary motion: motion in a circle. D.
