Lesson 12: Using Peripheral Devices

What, if any, type of printer uses a fuser? A. Laser printer B. Color bubblejet printer C. A 3D printer D. Impact printer

A. Laser printer Laser printers are the type of printers that use fusers. Essentially, the laser heats up the toner and then transfers and bonds the toner to the paper using heat and pressure. Color bubblejet printers use micro-sprayers that spray droplets of ink at the paper to print. A 3D printer uses plastic, not ink, to print out objects in three dimensions. A fuser is not used in 3D printing. An impact printer is mechanical and much like the old typewriters. A hammer with letters embossed strikes a ribbon of ink. The embossed letters would transfer ink from the ribbon onto the paper.

What function of a scanner would you use if you want to convert a letter that someone has mailed to you into a computer-editable document? A. Optical Character Recognition (OCR). B. TWAIN C. Windows Image Acquisition (WIA) D. Portable Document Format (PDF) or Joint Photographic Experts Group (JPEG)

A. Optical Character Recognition (OCR). Use Optical Character Recognition (OCR) software to convert a text image into a computer-editable text document. TWAIN-based software it is not the function of a scanner. It is software that acts as the plug-and-play feature of scanners to connect to your computer. Older scanners use TWAIN-based software to interface with a computer. WIA is not a function, it is the plug-and-play software that newer scanners use. This software will present options for the image output. PDF or JPEG are the standard formats to which scanned images get converted to when they become digital files.

What do you need to know to connect to a device that is configured over the network? A. Typically, the Internet Protocol (IP) address of its management page or the device's hostname B. Typically, the Media Access Control (MAC) address of the device you want to connect to C. Typically, the physical location of the computer D. Typically, the port in the wall where the network cable is plugged into

A. Typically, the Internet Protocol (IP) address of its management page or the device's hostname There are a couple of ways to find a network device if it is configured to be shared across the network and you wish to access it. You can either get to it via the IP address which is assigned to it by your administrator or the hostname. You are also likely to be prompted for a user name and password. While it is true that every device on the network has a MAC address, the switches that control the network use this to identify each device in the network. You do not need to know the physical location of the computer. It does not matter if the computer is in the same room as you or across town. You don't need to know the specific port on the wall in which it is plugged in. Devices on a network use IP address or hostnames.

Which four toners are used to produce color prints? A. Red, green, blue, black B. Cyan, magenta, yellow, and black C. Red, blue, yellow, and black D. Light blue, pink, yellow, black

B. Cyan, magenta, yellow, and black Printers use the CMYK color model. CMYK stands for Cyan, Magenta, Yellow, and Black. "K" denotes black to prevent confusion with blue. This model is used in printing where layers of colors are removed or filtered out depending on the desired color. Combining the primary colors in equal parts create the black color. Most printers also carry black ink to reduce the quantity of CMY used. Printers do not use red, green, blue, and black (RGB); however, this color scheme is used by monitors for displaying color images. Combining the primary colors in equal parts create a pure white color. Printers do not use red, blue, yellow and black color schemes; however, the RBY scheme is used by artists for creating all colors needed while painting. Although cyan looks like a light blue and magenta looks like pink, these are not the true names of the colors used by a printer.

Which of these statements is true regarding how you set up your display? A. Dots Per Inch (DPI) or scaling is configured via the Personalization applet. B. Dots Per Inch (DPI) or scaling is configured via Display settings. C. Dots Per Inch (DPI) is determined by the monitor and device driver and cannot be user configured. D. Dots Per Inch (DPI) or scaling is configurable using your computers IP-based interface.

B. Dots Per Inch (DPI) or scaling is configured via Display settings. Dots Per Inch (DPI) or scaling is configured via Display properties settings. This can be accessed by right clicking on the Desktop and clicking "Display settings." Personalization is for configuring themes and the appearance of the desktop, not for resolution or DPI. Dots Per Inch is a user configurable setting that changes the way an operating system displays on a monitor. Not all DPI settings will look good on all monitors. Network devices have IP-based interfaces for making configuration changes. PCs typically do not use IP-based interfaces for configuring settings.

You are configuring dual monitors positioned side-by-side. You want to increase the amount of screen space available. Which multiple display option should you set? A. Portrait orientation B. Extend the displays. C. Show only on display #2 D. Duplicate the displays.

B. Extend the displays. When you have dual monitors side by side and want to increase the space so that you can view your desktop across the length of both displays, you should go to the Display tab in the System node of the Settings app. The "Extend these displays" option allows for a desktop that stretches across multiple monitors. Portrait orientation will set it up so that you can view the screens rotated 90 degrees from the standard. Selecting the "show only on display 2" option only display the desktop on whichever device is identified as #2. Selecting the "Duplicate the displays" option will display the same desktop image on multiple displays. This option is ideal for delivering presentations.

What type of print technology uses toner? A. Inkjet B. Thermal transfer B. Laser D. Impact

B. Laser Laser printers are the type of printers that use fusers. Essentially, the laser heats up the toner and then transfer and bonds the toner to the paper using heat and pressure. Inkjet printers use micro-sprayers that spray droplets of ink at the paper to print. Thermal printing is a digital printing process which produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image. Impact printers are mechanical and much like the old typewriters. A hammer with the letters embossed strike a ribbon of ink, and letters transfer through the ink ribbon and pound the letter onto the paper.

You are trying to find a use for an old dot matrix printer. The only port on the printer is a large edge-style one with 36 contacts. What type of port is this? A. USB port B. Parallel port C. HDMI port D. RJ45 port

B. Parallel port The old legacy large edge-style connector with 36 contacts (pins) are called Parallel port connectors. The name refers to the way the data is sent; parallel ports send multiple bits of data at once, in parallel communication, as opposed to serial interfaces that send bits one at a time. USB is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply between personal computers and their peripheral devices. Old dot matrix printers did not have USB ports. Printers do not use the HDMI connection. An HDMI connection is used for digital video and audio output devices. Although printers may use RJ-45 network ports to connect to a network, old dot matrix printer technology used parallel ports.

You need to plug a microphone into a computer to make a recording. How would you identify which jack to use? A. The jack is color-coded green. B. The jack is color-coded pink. C. Plug into the RJ45 Jack. C. Use the HDMI connection.

B. The jack is color-coded pink. Generally, most basic computer microphones will have one of two varieties of jack: an 1/8" TRS jack, which is essentially the same kind of jack you would find on a pair of headphones (usually colored pink), or a USB jack, which is flat. Both of these jacks have corresponding ports on most computers. The green jack is an output audio jack and it is used to connect speakers to your computer as an output for sound. The RJ45 Jack is used to connect a network cable to your computer. The network connection is not an input jack capable of relaying sound to a sound card. The HDMI cable is used for audio/video output, not for audio input.

What type of wired interface is a printer MOST likely to use? A. HDMI B. USB C. VGA D. S/PDIF

B. USB Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply between personal computers and their peripheral devices. USB is the type of wired connection that you would most likely use for a printer. Printers do not use the HDMI connection. An HDMI connection is used for digital video and audio output devices. Printers do not use the VGA wired interface because that is used for legacy monitor connections. A Sony/Phillips Digital Interface (S/PDIF) jack is used on higher end sound cards to transmit digital signals to surround sound speaker systems.

What basic command demonstrates that a printer is connected properly to a computer and that its driver is installed correctly for Windows? A. Run the troubleshooter B. Check devices and features C. Print test page. D. Printing preferences

C. Print test page. Print test page will print a page to see if the driver is installed correctly. It will also allow you to check that text and graphics can be printed correctly by the printer. The test page normally also shows you extra information such as the driver software version which can be used to if you need to troubleshoot problems. Checking devices and features will allow you to see if a printer is present. It will not necessarily demonstrate that the printer is connected properly and that the drivers are properly loaded to Windows. Running the troubleshooter may assist you in identifying problems with the driver or configuration errors, but it is a process (wizard), not a basic command. Printing preferences will bring up options on how you want the printer to process your projects. It does not test the status of your printer and its driver.

You want to configure a printer to use both sides of the paper (duplex) by default. You have alt-clicked the printer object. Which command should you select to proceed? A. Open B. Printer properties C. Printing preferences D. Troubleshoot

C. Printing preferences Alt-clicking the printer object opens a menu with several options. If supported by your printer, you can select the duplex option by selecting the printing preferences option. After alt-clicking, the printer properties option can be used to change a printer name, sharing, and advanced configuration; however, the duplex option is not located here. The open option on the menu will display the printer queue and, depending on the print driver, offer options for other functionality. The troubleshoot option invokes Windows diagnostic troubleshooting wizard. This is used when the device is not functioning properly, not to configure duplex printing.

A printer is rated at 20ppm. What is the significance of this statistic? A. This is the number of projects per minute that your printer can handle. B. This is an image format used to measure the quality of an image the printer can produce. C. This is the number of pages per minute the printer can output. D. High page rates are important in high-volume environments. This is the voltage measurement of your printer.

C. This is the number of pages per minute the printer can output. Pages per minute (PPM) is the speed measurement of the printer's printing capability. PPM is used to measure the printing speed of both inkjet and laser printers. Most printers include a PPM rating for both black and color documents. These speed measurements are typically listed in the printer's technical specifications. Portable Pixel Map (PPM) is an image format typically used to allow monochrome bitmaps to be transmitted within an email message as plain ASCII text, allowing it to survive any changes in text formatting. Project Portfolio Management (PPM) is the centralized management of the processes, methods, and technologies used by project managers and project management offices. It is not related to printing. Pulse Power Measurement (PPM) is a voltage measurement not related to printers.

Which Windows interface is used for advanced management and troubleshooting of devices? A. Display tab B. Web configuration C. Personalization applet D. Device manager

D. Device manager Device Manager is used to update drivers and obtain more advanced troubleshooting information. The basic user interface is either Devices and Printers or the device pages in the Settings app, depending on the Windows version. Web configuration is an interface used to configure IP-based peripherals and is accessed using a web browser. Only devices with IP addresses can be managed this way. The Personalization applet is used to customize options for almost any aspect of how Windows is displayed. The display tab is part of the System settings and is used to adjust screen resolution, scale, and layout.

Which of these statements is false? A. You can transfer images from the camera over Wi-Fi or Bluetooth if supported. B. You can connect the camera itself to the PC over a USB cable. C. You can remove the flash media from the camera and insert it into a flash reader. D. You can connect the camera's flash memory card directly into your computer's USB port.

D. You can connect the camera's flash memory card directly into your computer's USB port. There are several different methods for retrieving images from a camera. Of those methods, connecting the camera's flash memory card directly into the computer's USB port is NOT one of them. A special reader for the flash card would be required. Most cameras have USB ports that can be used to connect the camera directly to the USB port on the computer. This technique leaves the flash card in place and transfers images directly from camera to computer. Most cameras have removable flash media that can be removed from the camera and inserted into a flash reader. Some computers have integrated readers while others will require a USB-connected reader. Modern cameras have Wi-Fi and/or Bluetooth functionality that can be used to transfer images to a network storage device or a computer.
