QuestionAnswer
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.
IR transceiver Provides an infrared port for wireless communication
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.
isochronous data transfer A data transfer method used by IEEE 1394 where data is transferred continuously without breaks.
KVM (Keyboard, Video, and Mouse) switch A switch used to connect a single keyboard, mouse, and monitor to multiple computers.

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.
