    • Keyswitched and Capacitive.
    • "Debouncing" refers to______.
    • Cleaning up keyboard signals and preventing multiple characters from a single keypress.
    • What monitor has the highest resolution?
    • XGA. Could support 256 colors at 1,024 x 768 pixels.
    • Which type of computer communication uses a separate timing signal to dictate transmission times?
    • Synchronous. Synchronous communications uses a clock signal that is separte from the data signal;communication can only happen during a tick of the timing signal.
    • Which IRQ does COM 1 share with COM 3?
    • 4.Because of the configuration of the original 8-bit bus that supported only 8 IRQs, when COM 3 was added, it had to share IRQ4 with COM 1.
    • Which type of mouse interface is a small, round PS/2 connector and is attached to an 8-bit interface card that is installed directly onto the computer's bus?
    • Bus mouse interface. The bus mouse interface is a small, round PS/2 connector and is attached to an 8-bit interface card that is installed directly onto the computer's bus.
    • Which type of output device draws the image with a pen one shape at a time and uses CAD software to produce blueprints or tehnical diagrams?
    • Plotters. Draw the image with a pen one shape at a time and use CAD software to produce blueprints or technical software.
    • Which LCD maxtix screen works in a manner similar to an LCD watch.
    • Active maxtrix. The LCD watch was the precursor technology to active matrix LCD screens.
    • If a display adapter is a VGA adapter in the standard configuration, what would the default resolution/color be?
    • 640 x 480 with 16 colors. This video technology had 256Kb of video memory on board and could display 16 colors at 640 x 480 pixels.
    • All of the following(EGA,CGA,VGA,XGA,SVGA,DVGA) can be considered video technologies except_________.
    • DVGA.
    • A VGA extension cable will have____.
    • DB-15M to DB-15M. The VGA extension cable will have a DB-15M on both connectors.
    • Which of the following types of output devices puts computer data on paper?
      Modems,Monitors,LCDs,Printers
    • Printers
    • Which type of output device has the highest resolution(therefore the best quality)?
    • EP Printers. The images produced by electorphotographic(EP) printers are of the very best quality and they produce these images at higher speeds.
    • COM 1 shares an IRQ with which other COM port?
    • COM 3. Because of the congfiguration of the original 8-bit bus (which supported only 8 IRQs,and had only COM 1 and COM 2), when COM 3 was added later, it shared the IRQ with COM 1.
    • Which type of scanner gives the best quality and highest resolution?
    • Flatbed.
    • Which type of signal degrades the most over longer distances?
    • Digital. Of the signals listed, digital is least suited for long distances because it degrades the most.
    • What is the maximum practical length of a standard parallel printer cable?
    • 10 feet. You can buy longer standard cables but it is recommended you don't use them.because of data loss problems with cables over 10 feet.
    • You find a cable in a box of old computer parts. It has a DB-25F connector on both ends. What kind of cable is it most likely to be?
    • Null modem cable. A cable with both ends having a DB-25F connector is classified as a null modem cable.
    • Which types of mouse interface technology use an interrupt (other than the ones a PC is normally using)?
    • Bus and PS/2. The PS/2 and bus mouse technology use a separate interrupt.
