Firewire

Firewire is a high speed bus that supports data transfer rates up to 400Mbps (100/200/400 Mbps selectable) and delivers more than 30 times the bandwidth of the popular USB peripheral standard.

HDC

Hard Disk Controller is a special-purpose chip and circuitry that directs and controls reading from and writing to a computer’s disk drive.

IDE

Integrated Device Electronics is a disk drive interface where the controller electronics reside on the drive itself. This allows elimination of the need for a separate adapter card.

IEEE

IEEE stands for Institute of Electrical and Electronics Engineers, pronounced “I-triple-E.” Founded in 1963, IEEE is an organization composed of engineers, scientists, and students. IEEE is best known for developing standards for the computer and electronics industry.

I/O

I/O (Input/output). Two of the three activities that characterize a computer (input, processing, and output). Refers to the complementary tasks of gathering data for the microprocessor to work with and making the results available to the user through a device such as the display, disk drive, or printer.

IRQ

IRQ (Interrupt ReQuest). A method by which a device can request to be serviced by the device’s software driver. The system board uses a PIC to monitor the priority of the requests from all devices. When a request occurs, a microprocessor suspends the current operation and gives control to the device driver associated with the interrupt.

ISA

ISA (Industry Standard Architecture) is an 8-bit / 16-bit bus that provides a buffered interface from devices on expansion cards to the PC internal bus.

LAN

LAN (Local Area Network). A group of computers and other devices spanned over a relatively limited area (i.e. a single building).

LBA

LBA (Logical Block Address). A unit of data supplied or requested by a host computer.

MIDI

MIDI (Musical Instrument Digital Interface). An industry-standard connection for computer control of musical instruments and devices. A hardware and data standard for communicating between hardware. Most
