QuestionAnswer
What does an interlaced display do? A type of display in which the electronic beam of a monitor draws every other line with each pass, which lessens the overall effect of a lower refresh rate.
What does an IR transceiver have to do with wireless communication? Provides an infrared port for wireless communication.
A IrDA (Infrared Data Association) transceiver is another name for? Another term for an infrared transceiver.
What does a isochronous data transfer do with data? A method used by IEEE 1394 to transfer data continuously without breaks.
What does an IRQ (Interrupt ReQuest) line device do? A line on a parallel port. BIOS manages these request lines that are used by a device to hail the CP U asking for data to be processed, and you do not need to change this value.
What does a isochronous data transfer...well transfer? A data transfer method used by IEEE 1394 where data is transferred continuously without breaks.
Whats a KVM (Keyboard, Video, and Mouse) switch used for? A switch used to connect a single keyboard, mouse, and monitor to multiple computers.
Whats is a LCD monitor described as? A thin, flat monitor based on a technology that manipulates liquid crystals.
Whats another term for a motherboard mouse? Another term for a PS/2 mouse.
What kind of port is an LPT (Line Printer Terminal) and were is it located? A parallel port in device Manager.
What can a native resolution do to a monitor? The one resolution for an LCD monitor, which is the actual (and fixed) number of pixels built into the monitor.
What kind of display is an noninterlaced? A type of display in which the electronic beam of a monitor draws every line on the screen with each pass.
What does a refresh rate do? The process of periodically rewriting data, such as on dynamic RAM.
Whats a resolution? The number of pixels on a monitor screen that are addressable by software (example: 1024 x 768 pixels).
What was a RGB (red, green, and blue) used for? Used by older video cards and CRT monitors. RS-232c (Reference Standard 232 revision c or Recommended Standard 232 revision c): A serial port interface standard.
What kind of port is an standard parallel port (SPP)and what does it do? A standard port allows data to flow in only one direction and is the slowest of the three types of parallel ports. The standard parallel port is sometimes called a normal parallel port or a Centronics port.
What does a Super VGA (SVGA) have to do with a monitor? A monitor using a minimum refresh rate standard of 70 Hz, or 70 complete vertical refreshes per second.
Whats a S-Video port used for? A 15-pin video port used on a desktop or notebook computer to connect a projector.
What does a touch screen have to do with a monitor? An input device that uses a monitor or LCD panel as a backdrop for user options. Touch screens can be embedded in a monitor or LCD panel or installed as an add-on device.
What does a UART (universal asynchronous receiver-transmitter) chip do? A chip that controls serial ports. It sets protocol and converts parallel data bits received from the system bus into serial bits.
How does VGA (Video Graphics Adapter) relate to a (RGB)? The standard analog vide o method of passing three separate signals for red, green, and blue (RGB), which older video cards and CRT monitors use.
