5: Viruses and their Types Bomb, Phage, Trojan Horse, and Hoax Bomb goes off at a specific time. Worm takes a little memory at a time. Phage happens on a database, operating system, or PDA. Trojan Horse looks like something good but contains a virus. Hoax is a virus that is a trick.

11: Speech Recognition I believe that speech recognition is very useful. Many people thought it would be fun, but were very frustrated by it. I thought it would be fun and I was correct. I really liked it because for once, my hands weren't cramping up. All I had to do was talk to it. It saved a lot of time, typing, and most importantly pain. Speech recognition is great in my opinion and many others thought that. Sure it's not perfect, it will miss a word every once in a while, but my speech recognition had spectacular accuracy! Through proper training speech recognition can be fun. It is really useful and I hope one day that more people will be open to try it.

12: Objective 4 Alternative Input Devices

13: Here are some Alternative Input Devices... Keyboards Controllers/Joysticks The Stylus USB Flash Drives Environmental Control Units Microphones PDA's Tablet PC's Camcorders and More!

14: Controllers/Joysticks The first electrical 2-axis joystick was invented about 1944, which was made in Germany. The first controller was invented in 1985 in Japan. There are many types of controllers: Keyboard, mouse, gamepad, paddle, handheld, steering wheel, touch screen, motion sensing, wireless, instrument, gun, etc. They were made for fun and profit, on the other hand the joystick was originally for fighter planes but later adapted to video games for fun. The average controller or joystick can cost anywhere from $19.99-$39.99 and up.

15: The Stylus A Stylus is a "Stick" that is used for PDA's and Tablet PC's and is very useful for artists. The first stylus was used by Mesopotamians to write in cuneiform. They were made of copper reeds, bones, or metal. Until the 19Th century they had only been used on a wax covered plate. Now they are used for many things which include artwork and even some video games.

16: USB Flash Drives A USB is a type of storage device. They have virtually replaced CD's and floppy disks. Over the years they continue to drop in price while gaining more storage and speed. They come in many shapes, sizes, and colors. The most common is black and rectangular, but some look like other items or things. They are simply plugged into a computer and move or transfer data. People that would use them would be like a business man, or a student, or anyone really.

17: Environmental Control Units (ECU) It is a device (like a smart house) that controls everyday tasks around a house such as lighting, television, radios and many other things. It is very useful for disabled people and are often voice activated. They cost a lot of money but seem to be very helpful. Anyone can use them but are usually the most helpful to disabled people. It also does simple things like turning off lights when you leave the house or turning them on as you enter.

18: Tablet PC's Is similar to a laptop with a pullout screen and touch screen or a slate. Can be used with a stylus, digital pen, or finger. Tablet PC's were first announced by Microsoft in 2001. A tablet PC can be used by anyone and are used for work, jobs, or even just fun! Some good things are that they are light weight, portable, and can be written on instead of typed. Some bad things about them are that they can be easily scratched, they have moving parts that break, and cost twice as much as a regular laptop.

19: Digital Camcorders An electronic input device that can upload videos onto a computer. Primarily designed to capture videos. The firs camcorder was the Sony Beta Movie, which was introduced in 1983. Anyone can use these and for many different reasons. They capture videos then can be put in a flash drive or hard drive. They can be big or very small and portable. They record, play back videos, can be watched on a TV, sync with a computer, zoom in/out, and add color effects.

20: The GPS A GPS is a U.S. - Space based navigation system. It positions, tracks, and finds things. Anyone can use a GPS. For anyone that has a GPS system, it can provide accurate location and time. Some even tell weather and temperature. Most people that have a GPS travel a lot or just have no sense of direction.

21: Phone Generations 1G signifies the first- generation of wireless analog phones that originated in the 1980's. Analog Mobile Phone Service (AMPS). Martin Cooper invented the first mobile phone. 2G is second- generation and is when GSM (Global System for Mobile communications) first appeared. It also introduced SMS or text messaging. The first text message was sent to Finland in 1993. 3G features high-speed transmission, multimedia access, and global roaming. It allows IP access while being mobile with your device.

22: Phone Generations continued... 1G 2G

23: 3G

24: Objective 9 Leadership

25: Accountability & Victimization Some signs of Victimization are: Using confusion as an excuse. Unwillingness to ask questions. Viewing the world as a pessimist. Repeatedly becoming defensive and so on. Below the Line Wait and see, Ignore/Deny, It's not my job, Finger Pointing, Confusion tell me what to do, Cover your tail, Wait and See. Steps to Accountability are : (These are above the line) See it, Own it, Solve it, Do it.

26: Some Victim phrases are: I don't see any problem. It's not my job. That's unfair. I didn't because... No one else ever does that! What more can I do? Etc.

32: Memos Memos are easy to do you can just use the default in Windows. The order is: TO: FROM: CC: DATE: RE: MESSAGE:

33: Reports: Unbound reports are short reports without binders and stuff. Bound reports are longer and need a binder or something holding them together. For Academics no title page is needed.

34: In reports they all have a title page, table of contents, outline, and bibliography or references. Margins are usually 2" on the top first page, 1" on sides, on the second page the top margin is 1", and bottom is 1" depending on page breaks.

35: Tables: They are easy to make by using the default ones and then organizing data in columns and rows. Also, they will have a main title and subtitles.

(Main Entries) Outline Paragraph headings are indented .5” from the left margin and end with a period Capitalize the letter unless proper noun. (Secondary entries) Outline Key references/bibliography on the last page or on a separate page of the report in hanging indent style

50: Objective 6 Spreadsheets

51: Spreadsheet Formulas Some spreadsheet formulas you need to know are: =sum(A2:A5) =average(A2:A4) =(b12+b11) =(c5-c9) =(c2*c4) =(d4/d1)

52: A cell is a single block in a spreadsheet A column is a vertical group of cells ABC A row is a horizontal group of cells 123 A formula is the letters or numbers you put in a cell EX. =AVERAGE(B2:B5)

53: Spreadsheets are the most common software on every computer because they can be used for so many things like checks and budgets... B17 Letter before number when called out (like Battleship) Fast and Accurate Can answer “What is?” students’ current grade (school), individual athlete statistics (sports), transportation schedules (business), current $ available for spending (personal), census results. Can answer “What if?” student population increase(school), win/loss record change(sports), product sales decrease(business), hourly wage rate changes(personal).

54: Active Cell- The cell ready for data entry Alignment- When data is entered into a cell, the default alignment is labels to the left and values to the right Cell- Intersection of a row and column and is identified by a cell reference. Cell range- A selected group of cells that form a rectangle Cell reference- The column letter and the row number Example: C12 Column- Identified by letters that appear at the top of the spreadsheetVertical Formula- Equations with symbols for math operations Example =B6+B7+b8+B9 Function- Special formulas that do not use operators to calculate a result i.e. A shortcut formula Example: =sum(A6:A9) Label- Text, symbols, dates, or numbers not used in calculations

55: Rows- Identified by numbers on the left side of the spreadsheet Horizontal Spreadsheet- A program that allows you to use rows and columns of data to manage, predict, and present information. Value- A number entered into a spreadsheet cell that will be used for calculations Sum- Adds the range Average- Averages the range Add+A1+B1 Subtract-C3-D4 Multiply*B6*A2 Divide/F1/F3 Parenthesis() Exponent ^ Please Excuse My Dear Aunt Sallie Parenthesis Exponent Multiply Divide Add Subtract P.E.M.D.A.S.
