<p>Slide 1</p> <p>Lesson 4: Using Input/Output Devices input/output devicescommon input devicescommon output devicesspecialized deviceshow a device connectswhat a port iswhat a device driver is</p> <p> CCI Learning Solutions Inc.1Pg 15This outlines the topics to be discussed in this lesson.If possible, have actual input or output devices to show the students. For the most part, even if you dont have actual hardware components, students should be able to recognize the devices from the pictures.Be prepared to answer questions at different stages from students regarding how to use certain devices (such as digital cameras or scanners), which goes beyond this course. You may also want to address how many of the newer input devices are designed for a specific purpose as driven by market requirements, e.g., ergonomics, disabled users who need technologies such as voice recognition for inputting data, flat screens to reduce glare or desk space, infrared and cordless devices that address issues such as space or technology advances, etc. Although this portion of the exam addresses hardware considerations, you may also want to briefly introduce some software considerations for the input devices such as device drivers, specific software, etc. You may want to include in your discussion issues such as how the software may influence how the device responds with existing software installed. For example, the device driver for the printer identifies the printer brand model and the operating systems it was originally designed for; if you upgrade your Windows version, you may need to also update the printer driver in order to be able to use the same printer with the new Windows version.1 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsWhat are Input/Output Devices?Enables communication between user and computerThree classifications of Input/Output devices:Send information to computerDisplay or transmit information from computerCommunicate between computersInput deviceAnything used to enter data into computer Output deviceAnything used to display data on or from computer CCI Learning Solutions Inc.2Pg 15Objectives 1-1.1.5Discuss differences between input and output, and how some components can be either internal or external.Be sure to emphasize how important it is to make sure the plug and port match. Sometimes components dont work because they were plugged into the wrong type of port, e.g., 9-pin versus 12-pin, matching colors with colors on new computers, not forcing USB port, etc.Briefly discuss possibility of bent pins as well and their effect on the device, e.g., may work initially but will eventually stop working.2 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsInput device used to send information to computerInput alphanumeric data or instruct computer via series of keystrokes</p> <p>Using the Keyboard CCI Learning Solutions Inc.3Windows KeyEscape KeyFunction KeysAlt KeyCtrl KeyCursor Movement KeysNumeric KeypadPg 15Objective 1-1.1.5Check your classroom to see that all your keyboards are similar (e.g., [Windows] and [Application] keys available). If your classroom has a mixture, you may want to try and arrange to have only the newer keyboards available to your students.When discussing the keyboard, have students identify where these keys are on the keyboard, especially since there are some keys duplicated in different locations.3 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsUsing the Keyboard CCI Learning Solutions Inc.4Some keyboards ergonomically designed to reduce or prevent stress on wrists Some keyboards contain buttons to enhance multimedia experienceRegardless of keyboard type, same keys are available for document processingSpecial keyboards can be purchased for game enthusiasts or for people with disabilities </p> <p>Pg 16Briefly discuss the option of purchasing different types of keyboards for different purposes, e.g., easy/hard to press keys, sound keys make when pressed, standard versus cordless, extra keys, ergonomic, etc.Also briefly discuss how the prices will vary based on what options are selected. For instance, a standard keyboard (101 Enhanced keys with the cable) will cost approximately $20 whereas a cordless ergonomic keyboard may cost upwards of $50+.4 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing Fundamentals CCI Learning Solutions Inc.5Using the KeyboardExecutes typed command, performs selected option, marks end of line, or creates blank line.Deletes one character to left of flashing cursor; may show as left arrow ().Also on numeric keypad as ; deletes character above or to right of flashing cursor. Inserts blank space between words or sentences.Cancels current selection, or generates special code for computer; called Escape key.Advances cursor to right by specified number of spaces in word processing program, or to next cell in spreadsheet program.Selects uppercase letters for typewriter keys and punctuation symbols on number keys. Can use with other keys to perform function or task.</p> <p> Pg 16Spend some time looking at the keyboard and identifying where keys are, how similar it is to typewriter keys (if applicable) except for Function keys, direction keys, and numeric keypad.Also spend time ensuring students understand where standard keys are (e.g., [Tab], [Spacebar], [Backspace], [Insert], [Delete], [Enter], and the arrow keys). These will be important keys for daily processing; recognition of the other keys seems to fall into place once they are comfortable with the location of these keys.Make sure students understand that [Ctrl], [Shift], and [Alt] by themselves do nothing, but when held down in conjunction with another key will perform a specific task. Be sure to provide some examples of same, and demonstrate these in the Windows section of this Module.While it isnt necessary to go into too much detail about these keys right now, the main point here should be to ensure students know and recognize these keys. Many of them will be similar to those found on a typewriter, but for those who havent used a typewriter before, this will be a good starter and a refresher for others.Allude to the point that these are the most commonly used keys when working with files and each performs a specific task, depending on the software program.</p> <p>5 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing Fundamentals CCI Learning Solutions Inc.6Using the KeyboardLocks letter keys to produce only uppercase characters.Provides secondary meaning or function for specific keys. Displays Start menu.Displays shortcut menu similar to right-clicking item. Options in menu depend on where mouse pointer was when key pressed.Provides secondary meaning or function for specific keys.Move cursor up, down, left or right. Located between typewriter keys and numeric keypad. Captures information on screen and sends to Windows Clipboard.Toggle (start and stop) scrolling display of data on screen. +Stop or freeze computer, then continues when any key pressed; sends Break code to computer to unfreeze or unhang computer. </p> <p> Pg 16-17Objective 1-1.1.5It may not be necessary to spend much time on the last three keys as they arent used that often. However, introduce them to the student so they know where the key can be found and its main purpose.</p> <p>6 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing Fundamentals CCI Learning Solutions Inc.7Using the KeyboardFunction KeysLocated along top rowLabeled through toEach key assigned special meaning or function in application programsPrimary purpose to provide shortcut for commonly used commandsCursor and Numeric KeypadCan toggle on and off by pressing keyWhen on, pad becomes calculator or numeric padWhen off, pad becomes arrow or cursor movement pad</p> <p> Pg 17Spend time making sure students recognize these parts of the keyboard. While most of the function keys are not as popular as with past versions of application programs, they can still provide an opportunity to lead a discussion of how many people begin to combine shortcut keystrokes with the mouse to navigate or activate items, e.g., [Ctrl]+[S] to quickly save while using the mouse to scroll through the document. You may also want to provide an example of how the functions might be used outside of popular desktop applications, e.g., customized programs such as retail, insurance, etc.Provide examples of how advantageous using the Numeric keypad may be when entering numeric data, especially for those who have used the 10-Key method for inputting values. Definitely make a point of having students understand the [Num Lock] key and how it affects data entry.You can also provide a bit of history here by discussing how earlier keyboards did not have the cursor movement keys to the left of the numeric keypad and how cumbersome it was to constantly turn [Num Lock] on and off as needed.</p> <p>7 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsUsing Pointing DevicesEnables you to select or activate items on screen by placing pointer arrow on item and performing required actionTraditional pointer device is a mouseMove mouse on flat surface causes mouse to initiate movement reflected by pointer on monitorTraditional mouse uses ball that rotates to initiate movement as you move mouse device Trackball has ball on side where your thumb rests; rotateball to move pointerNewer mouse models use optical light or diode technology to move pointer on screen CCI Learning Solutions Inc.8</p> <p>Pg 17Objectives 1-1.1.5Be prepared to spend time showing students how to hold the mouse, move it around on the desk, and use the buttons. This is a perfect time to practice using the left and right mouse buttons with the computer turned off, so theres no chance of having to undo items on the screen.The pictures here show a traditional mouse and trackball. Briefly discuss optical mice that use infrared instead of a traditional ball.</p> <p>8 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing Fundamentals CCI Learning Solutions Inc.9Using the MouseClickPoint mouse cursor at item, then press left mouse button once and release button to select item.Double-ClickPoint mouse cursor at item and then click left mouse button twice quickly to initiate programs or open files.Right-ClickPoint mouse cursor at item and then click right mouse button to display shortcut menu.Left DragPress and hold left mouse button while moving mouse moves items or selects multiple items.Right DragPress and hold right mouse button while moving mouse moves or copies items. When button released, shortcut menu appears for further command selection.Middle Wheel or ButtonCustomize to perform certain actions, e.g., use wheel to scroll up or down.Thumb ButtonsCustomize buttons where thumb rests for specific tasks. Pg 17Even though the machines may not be turned on at this time, have students try holding the mouse so they can become comfortable with how it should feel when they begin to use it. Many people who are new to computers are unsure how to hold the mouse and do not actually have a firm grip on the mouse, sliding it along the desk with a tentative hand. NOTE: This is especially true in classes for seniors who may have arthritis or are afraid of the mouse. Do not progress too far into the application part of the course if the students are not comfortable with the mouse.9 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsUsing Pointing DevicesTo select items, grasp mouse with palm downand index finger gently resting on left buttonSlide mouse flat along desk and mouse pointer moves in same direction on screenIf run out of space on desk, lift mouse and place in new position on desk, and continue movingTo cancel any option, click left button anywhere on screen away from option being selectedAvailable in traditional style or as wireless devicesCan work with PC or Mac CCI Learning Solutions Inc.10</p> <p>Pg 18Provide demonstrations on how to hold the mouse, where to place and rest the fingers, as well as how to press the buttons once for a click versus twice for a double-click. Without the computers being on you can get them comfortable with the mouse so that when you get to the Windows section, they will be able to confirm where the mouse is moving on the screen now that they have the right feel for the mouse.This may be a bit difficult to do without having the computers turned on. You may want to delay this slide or further discussion of this topic until you have students start the computer and then play with the mouse at the desktop screen.Discuss what running out of space on the desk means; this is common for new users and then they want to know how to get the mouse cursor to appear on the screen without having to bump into other items on the desk.10 CCI Learning Solutions Inc.Internet and Computing Core Certification Guide Module A Computing FundamentalsUsing Pointing DevicesTouchpad enables you to use finger to move pointerHas two buttons that work as left and right mouse buttons To move pointer around on screen, place finger on touchpad and glide in direction for pointer to move To select item, position pointer over item and then tap touchpad once or click left buttonTo activate item, position pointer over item and then tap touchpad twice in quick succession or double-click left buttonTo drag item, position pointer over item, press , and glide finger on touchpad to required locationTo display shortcut menu, position pointer over item and then click right buttonCan work with PC or Mac</p> <p> CCI Learning Solutions Inc.11</p> <p>Pg 18Objective 1-1.1.5This is a new sub-objective that has been added to the exam objectives and targets this pointing device. If possible, have a notebook available in the classroom that students can use to try the touchpad even if they arent using it on a regular basis. As notebooks are so popular, this pointing device now needs to be addressed.Take note that the Mac has only one button associated with the touchpad and you need to use that button to select and activate items; there is no matching option to tap the touchpad to select something, you must press the button to actually select or activate the item.
