Question | Answer |
interlaced | 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. |
infrared (IR) transceiver | A wireless transceiver that uses infrared technology to support some wireless devices such as keyboards, mice, and printers. Also
called an IrDA transceiver or infrared port. |
IR transceiver | Provides an infrared port for wireless communication. A motherboard
might have an embedded infrared transceiver, or the transceiver might plug into a USB
or serial port. |
IrDA (Infrared Data Association) transceiver | Another term for an infrared
transceiver. |
isochronous data transfer | A method used by IEEE 1394 to transfer data continuously
without breaks. |
IRQ (Interrupt ReQuest) line | 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. |
KVM (Keyboard, Video, and Mouse) switch | A switch used to connect a single
keyboard, mouse, and monitor to multiple computers. |
LCD monitor | A thin, flat monitor based on a technology that manipulates liquid
crystals. |
motherboard mouse | Another term for a PS/2 mouse. |
LPT (Line Printer Terminal) | A parallel port in device Manager. |
native resolution | The one resolution for an LCD monitor, which is the actual (and
fixed) number of pixels built into the monitor. |
noninterlaced | A type of display in which the electronic beam of a monitor draws
every line on the screen with each pass. |
refresh rate | The process of periodically rewriting data, such as on dynamic RAM. |
resolution | The number of pixels on a monitor screen that are addressable by software
(example: 1024 x 768 pixels). |
RGB (red, green, and blue) | 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. |
standard parallel port (SPP) | 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 (36-pin) port. |
Super VGA (SVGA) | A monitor using a minimum refresh rate standard of 70 Hz, or 70
complete vertical refreshes per second. |
S-Video port | A 15-pin video port used on a desktop or notebook computer to connect
a projector. |
touch screen | 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. |
UART (universal asynchronous receiver-transmitter) | A chip that controls serial
ports. It sets protocol and converts parallel data bits received from the system bus into
serial bits. |
VGA (Video Graphics Adapter) | 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. |
