FC: DCS For Dummies | By: Lane Williams

1: Types of Viruses | Viruses •A virus is a piece of code that is designed to cause damage to computer files. Bomb: •Are timed to hit at certain points. Worm: •Nibbles through your computer files. . •Tricks you into deleting files.

2: Types of Viruses Continued | Anti-Virus •Scans your computer to see if you have virus or malicious software. After scanning it can destroy or isolate the virus so it isn't malicious. Encryption •A secret code that nobody can read. Sounds like Egyptian, and Egyptians write in hieroglyphics that many people can't speak. 3 ways to know if a sites secure : https, the lock, and a seal

3: Ethics •What’s right is ethical, so ethical is the right thing to do. •A hacker is someone who finds “holes,” in a system to try and maliciously harm their files. •Piracy= taking flies that aren't yours illegally. Password= protects your computer with a unique code you need to remember to type in to have access to your computer.

4: Three Components of a Computer System | The first is System Software. System Software is the boss of the computer. The System Software is also the O.S. or Operating system.

5: The second is Hardware which is the physical components of a computer system. The Hardware has the process of , Input -> Processing ->Output ^Storage^

6: The third and final component is Application Software

7: •Anything that is used, such as Microsoft Word, or excel. • Spread sheets (calculations), Word processing (you make documents), Presentation Software (Microsoft PowerPoint), Publishing Software (Microsoft software), Databases (organizations), and Application Specific (Micro type, games, e-mail, virus protection, and firewall). | Application software is anything that is used, such as Microsoft Word, or excel. It can be used for spread sheets (calculations), Word processing (you make documents), Presentation Software (Microsoft PowerPoint), Publishing Software (Microsoft software), Databases (organizations), and Application Specific (Micro type, games, e-mail, virus protection, and firewall).

8: Classes of Software | Commercial Software -Costs money -Copyrighted, the owner contains the rights to sell it, and you need permission to copy it -Should never give viruses

9: Shareware -Copyright protected -Distributed free on a trial basis -3rd most likely to get viruses | Freeware -It is free -Copyrighted protected, so you can't sell or distribute the free product in case the owner wants to sell it -2nd most likely to get viruses from

10: Public Domain Software -The public has access to do what they want with Public Domain Software -Most likely to get viruses from here

11: Types of Hardware | The most common Input Devices are the keyboard and mouse. The most common processing device is the scanner. Processing holds RAM-or random access memory

12: The most common Storage Devices are the hard drive, flash drive, Cd's etc.Storage holds ROM- or read only memory

13: The most common output devices are the printer and the monitor.

14: Speech Recognition Software

15: When I first used Speech Recognition Software it was about what i expected it to be; it wasn't extremely accurate but it wasn't all that bad. It seemed to get better the more I used it, and it seemed to get to know my phrases more. In example, when I first said "Stalin's Russia," it said "stall in rush," but it quickly changed. A bad thing about Speech Recognition Software is if you are sick or have allergies that could mess with the system, and the software may think that your voice will normally sound like that.

16: Advantages | Speech Recognition Software is great because you can only type so fast, but you can speak much more fluently than you can type. Speech Recognition Software can also prevent painful conditions such as Carpal Tunnel Syndrome, and other repetitive strain injuries.

17: Disadvantages | Speech Recognition Software isn't always accurate, and can be a pain to use if the system doesn't recognize your voice. You can be frustrated easily by this software if it doesn't recognize your speech. If you have something wrong that causes your voice to sound different that data may be put into the machine and the system may not recognize your voice the next time you use it.

18: Alternative Input Devices:

19: USB Flash Drives

20: A USB flash drive is a small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive. Or in other words you can save to the USB, take it to another computer, plug it in to the USB port, open up a document, spreadsheet, power point, etc. and print it or save it to that specified computer.

22: Advantages | A USB flash drive is small, and can be taken anywhere because it is pocket sized. Also, it has no moving parts, and still can hold a considerable amount of memory.

23: Disadvantages | The Disadvantages of a USB flash drive is that it can only hold so much memory, and it cannot function by itself; or in other words it isn't like computer, it can only store memory and transfer it.

24: The History of a USB Flash Drive | The First creators of the USB flash drive, IBM, sold the first flash drive which was available on December 15, 2000. This flash drive could only hold 8 MB, which was five times the memory a floppy disk could hold at the time (1.44 MB).

26: Web Cell Phones

27: There are the 1G cell phones; in 1908 Nathan B. Stubblefield put out a patent for a wireless phone. In 1979 the first commercial citywide cellular network was launched in Japan. Fully automatic cell networks were first introduced in the mid- 1980s. In 1983 the first mobile phone was approved in the U.S. | The first second generation cellular technology was launched in Finland in 1991. The first person to person SMS text messages also appeared in Finland. The first content sent to cell phones was ring tones in Japan in 1999.

28: 3G In 2001 the first launch for the third generation of cell phones was launched also in Japan and we have been using the 3G ever since

29: Scientific Probes

30: A scientific probe is a device that can be connected to a computer or a graphic calculator to collect data.

31: Scientist use probes to research and learn more about place that they can not travel to Ex sending the space probes to Mar to learn more about what the planet is like and if people can live on it

32: Digital Camcorders

33: A digital camcorder is an electronic device that combines a video camera and a video recorder into one unit. Digital camcorders are usually priced from about $400 to $2000. For casual use, digital camcorders often cover weddings, birthdays, graduations ceremonies, kids growing up, and other personal events.

34: Digital camcorders are often used in the production of low-budget TV shows where the production crew doesn't have access to more expensive equipment. The phrase “digital video” refers to capturing, manipulation, and storage of motion images that can be displaced on a computer.

35: Three Components: | Digital camcorders contain three components: lens, imager, and recorder. The lens gathers and focuses the light on the imager. The imager converts incident light into an electrical signal. The recorder converts the electric signal into digital video and encodes it into a storable form.

36: Analog and Digital are the different formats of the digital camcorder. Analog format is the older format. For analog format, in order to display video images on a computer, the video signal had to first be converted from an analog to a digital format.

37: History | No one person is solely credited as having invented the digital camcorder. John Baird, a Scottish engineer, was one of the earliest pioneers in capturing moving images for television production.

38: Baird's experiments were built upon others that had come before him and much of the technology employed in the evolution of the video camera was built upon his findings

39: In the 1970s, the first portable video cameras emerged from JVC, and then models were released from Sony and RCA. The earliest camcorders employed analog recording onto videotape. Digital camcorders became available to the general public in the 1980’s. They were bulky, heavy, and expensive, but proved to be efficient.

40: Tablet PC's | Tablet PCs generally refers to a laptop equipped with a touch screen to operated with a stylus or finger tip instead of a keyboard or mouse. It is wireless personal computer (PC). Tablet PCs are often used where normal notebooks do not provide the particular function needed. Writing slates are Tablet PCs with the dedicated keyboard.

42: Advantages | The ability to us them in places that aren't conducive to keyboard and mouse, such as the bed, standing, or when you only have one hand. It records non-character based information, such as diagrams, mathematical notations, and symbols. It's lighter weight and lower power models can function similarly to dedicated reading devices.

43: Disadvantages | The price of a convertible Tablet PCs are high. The handwriting speed can be significantly slower than peak typing speeds which can be as high as 50-150 words per minutes (WPM). They have a higher risk for screen damage because the screen are exposed unlike laptops.

44: Features | It has capacitive technology, which senses the touch of finger with no pressure required. It has digital palm recognition technology. This prevents accidental contact from disturbing the pen's input. It has multi-touch recognizes which allows on-screen objects to be enhanced. It has sunlight readable display. This means that it can be read clearly even in bright direct sunlight. It docking station can improve the capability of the battery, keyboard, USB, RS232, LAN, and VGA.

45: The Computer Mouse | A computer mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface A mouse consist of an elements of an object held under one of the user's hands The computer mouse one of the most common input device

46: A computer mouse senses motion and clicks ands sends the information to the computer so it can respond appropriately A mouse today is connected by a USB cord to the computer Some older mice have a PS/2 connector A few of the older mice use a serial type of connector to attach to the computer

47: A ball inside the mouse touches the desktop and rolls when the mouse moves Two rollers inside the mouse. One roller is oriented so that it detects motion in the X direction. The other is oriented 90 degrees to the first one so it detects motion in the y direction The rollers connected to the shaft, and the shaft spins a disk with holes in it On either side of the disk there is an infrared LED and an infrared sensor

48: An on board processor chip reads the pulse from the infrared sensors and turns the into binary data that the computer under stands. The chip send the binary data to the computer through the mouse's cord. The inside of the mouse

49: In the beginning, there was no need to point because computers used crude interfaces like teletype machines for data entry Light pens were used on a variety of machines as a pointing device for many years When the mice hit the scene it was a success Compared to graphic tablets, mice are extremely inexpensive and they took up very little desk space.

50: Keyboards | Keyboards are a standard type of input on computers. They allow people to type data into the computer, use keys for a short cut to a certain program or tool, get out of programs, delete information quickly, print quickly, and numerous other things.

51: Where to buy Keyboards: | Keyboards can be on other devices such as a cell phone. Some phones have a standard keyboard and others have a qwerty keyboard. Some phones and other devices have a touch screen keyboard and others have both a touch screen keyboard and a touch screen keyboard. Some other devices that have keyboards include PDA’s,and I-pods.

52: Object 9 Leadership | Accountability: | No excuses! See the problem, own it, solve it, then do it! Don't stand around and complain, and be a victim. Accountability is a great thing for a leader to have, and to use.

53: Victimization: | Victims are people that like to complain, whine, and stand around and complain. They essentially have one cycle; First, ignore/deny, then, "It's not my job!" Finger pointing, Confusion, "Tell me what to do!" Cover your tail, wait and see if you get caught. Victims are never good leader, and are usually whiners and complainers.

54: Telltale Signs of Victimization: Being held prisoner by your circumstances. Feeling a loss of control over present circumstances. Paying no attention when others, directly or indirectly, provide feedback about what could or should have been done to achieve better results. Blaming or pointing fingers. Failing to confront issues. Directing discussions of problems toward what cannot be done rather than what can be done. Looking for collaborations of other person's injustices. Being unwilling to ask probing questions about personal accountability. Citing confusion as a reason for not acting. Wasting time and energy "bashing" others, especially those in authority. Viewing the world as a pessimist. Repeatedly becoming defensive. Avoiding people, meetings, and/or situations.

55: Victim Phrases: I don't see any problem. It's not my job. Just tell me what to do and I'll do it. Let's just wait and see what happens. There's nothing I can do about it. Someone ought to tell him/her. It wasn't my fault. I'm doing the best I can. I didn't because... All we can do is wait and see. That's too much work. What more can I do? Do you think i don't have anything else to do? If it were me, I'd do it differently. That's unfair. No one else ever does that. Somebody should do something about that.

56: (continued) That's just not the way my other teachers do it. If I do a great job, they'll expect it all the time. I would have but... That's too hard.

57: Letters | There are two types of letters; Business letters, and personal business letters. In a business letter you are representing a business that you work for or own. In a personal business letter you represent yourself. You can have modified block style letters, which is when the dateline begins at the center point on the stage. Letters can be opened or closes; Opened means that you omit punctuation in the salutation, and complimentary close.

66: Orientation- The determination of how material is arranged on a page. Portrait-taller than wide Landscape- wider than tall

67: Simple Reports | Unbound Reports (Business) - Typically short reports prepared without binders or covers. A multi-page report may be held together by paper clip or staple. Margins: Top margin on first page is 2” Top margin on succeeding pages is 1” Side margins are 1” Bottom margin is 1”, but may vary depending on page break decisions. Avoid widows and orphans. Additional formatting requirements: Center the title of the report In ALL CAPS, then quadruple space after the title before beginning the body of the report.

68: Double space the body of the report. Side headings are underlined and keyed in initial caps. Paragraph headings are indented .5” from the left margin and end with a period. Capitalize the 1st letter of the 1st word only. Key references/bibliography on the last page or on a separate page of the report in hanging-indent style. To cite sources, use textual citations within the report or key endnotes on the last page or on a separate page in hanging indent style. Page numbers (usually preceded by a last name) are located at the top right margin, .5” from the top, followed by a double space. The first page is usually not numbered.

69: Bound Reports (Business) – Typically longer reports are bound with covers or binders. Top, right and bottom margins are the same as for an unbound report. The left margin is increases to 1.5” to accommodate the binding. Typically longer than Unbound Reports. Academic Style Bound/Unbound Reports No title page is used for Academic style reports. Instead, key a heading in the top left corner on the first page. Double space between lines and include the following: Name of Student Name of Instructor Course Title Date in military style ( 12 November 2009) Double space body of the report—no exceptions

70: Outlines- a type of enumeration (numbering) that organizes information. The top margin is 2” or vertically centered. All other margins are the same as the report. Main and side entries or headings are used to organize information. Formatting for Main Entries in an Outline Preceded by capital Roman numerals (I, II, III, etc.) Use ALL CAPS or initials caps and bold Double space before and after a main entry. Formatting for Secondary Entries in an Outline Preceded by capital letters (A, B, C, etc.) Key

71: Key IMPORTANT words in initial caps Lower level entries are preceded by Arabic numbers (1, 2, 3, etc.) and lower-case letters (a, b, c, etc.) Only capitalize the 1st letter of the 1st word when keying these. Single space ALL secondary entries | Title Page (Cover Page) - only a Business Report (not an Academic Report) should include a Title Page. Center the page horizontally and vertically Include the following information (minimum): -Report Title -Writer’s Name - Date The course name and teacher’s name may also be included.

72: Table of Contents- An outline of the side and a paragraph heading in a report with their respective page numbers. Follows the Title Page. Margins are the same as for the report (using a 2” top margin). Center the heading in ALL CAPS Each entry refers to a major section and should be keyed in initial caps. Use right aligned tabs for creating leaders from the entry to its respective page number. Number the page at the bottom center using lowercase Roman numerals (I, ii, iii, etc.)

73: Bibliography – A listing of the material used in the report (textual citations, footnotes, endnotes, and related material which may have been used but not cited), located at the end of the report. Margins are the same as for the report (using a 2” top margin). Center the title in ALL CAPS followed by a quadruple space. (Proceed by QS if references begin after the report body on the same page.) List references in alphabetical order by author last name. Surname= last name Include a page number at the top right. Single space each entry; Double space between entries. Key each entry using a hanging indent (1st line begins at left margin; subsequent lines are indented by .5) Underline or italicize books, magazines and newspaper titles.

75: Works Cited – A listing of only those works that were cited in the report; located on a separate page at the end of the report. Follow the same formatting as that of a Bibliography. The difference is that you will only include those sources that were quoted or paraphrased. Do not include other reference materials on a works cited page.

76: Documentation of Sources: Enclose direct quotes of up to 3 lines in length in quotation marks. Quotes of 4 or more lies in length (long quotations) should be single-spaced and indents .5” from the left margin. An ellipsis () is used to indicate material that is omitted from a quotation. There are 3 methods of referencing cited material within the body of a report: -Textual Citations -Footnotes -Endnotes

77: Textual Citations: Typically keyed within parentheses immediately following the quoted material. Includes the name of the author(s), the year of publication, and the page number. Example: a textual citation. (Smith, 2003, 45)

78: Footnotes: When using footnotes, complete documentation for a reference is placed at the bottom of the same page. A divider line (preceded and followed by a DS) typically separates footnotes from the report body. Superscript numbers are used to consecutively identify each footnote. Indent the first line .5” from the left margin. Single-space each footnote; double-space between items.

79: Endnotes: Like footnotes, endnotes contain complete documentation for a reference. However, endnotes appear on a separate page at the end of the report. Use the same margins as for the 1st page of the report. Endnotes are formatted like footnotes with a corresponding superscript number and a 1st-line indent. Single-space each endnote; double-space between items. Include a page number at the top right.

81: Objective 6: Spreadsheets

82: Spreadsheets | Spreadsheet---- a program that allows you to use ROWS and COLUMNS of data to manage, predict, and present information. Advantages: Fast and Accurate Can Answer “What is?” Can Answer “What If?” 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 increases (school) Win/loss record changes (sports) Product sales decrease (business) Hourly wage rate changes (personal)

83: Spreadsheet Terms | Active cell- the cell ready for data entry. Alignment- when the 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: B12 Column- Identified by letters that appears at the top of the spreadsheet. (Vertical) 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. 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.

84: Label- Text, symbols, dates, or numbers not used in calculations. 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.

85: Formulas A tool for making calculations with the numbers on your spreadsheet. Add +A1+B1 Subtract – C3-D4 Multiply*B6*A2 Divide/F1/F3 Order of Operations You can also use parenthesis in your calculations where the order of operations is completed first: (A1+A2)*(B7/D4) (7+11)*(4/2) 18*2

86: Objective 7: Databases

87: Database-a comprehensive collection of related data organized for convenient access, generally in a computer. The main four things in a database are: Reports; Tables; Forms; and Queries. -Reports print out data in a database -Tables contain the data -Forms are customer information in a database -Queries questions answered in short detail Criteria in a database is a certain range of data in a database. For example, anyone over the age of 25 in Bessemer City. Rows are called Records in Databases Columns are called fields Fields are included in the reports.

89: Databases are used to find specific data in a company or other things. For example, in a video store there are many things that can be put into a database, such as member data, video data, and so on. There can be relations in tables, it can be either many to many, one to many relation. In Example, One Customer can rent many different videos, and on the other hand many customers can rent many videos and so on.
