Glossary of Terms and Abbreviations A Table 10. Glossary of Terms and Abbreviations Term Definition Active Termination The electrical connection required at each end of the SCSI bus, composed of active voltage regulation and a set of termination resistors. Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, and Ultra320 SCSI require active termination. BIOS Basic Input/Output System. Software that provides basic read/write capability. Usually kept as firmware (ROM based). The system BIOS on the mainboard of a computer is used to boot and control the system. The SCSI BIOS on your host adapter acts as an extension of the system BIOS. Refers to the way a computer is setup; the combined hardware components (computer, Configuration monitor, keyboard, and peripheral devices) that make up a computer system; or the software settings that allow the hardware components to communicate with each other. Device Driver A program that allows a microprocessor (through the operating system) to direct the operation of a peripheral device. Differential SCSI A hardware configuration for connecting SCSI devices. It uses a pair of lines for each signal transfer (as opposed to Single-Ended SCSI which references each SCSI signal to a common ground). Domain Validation Domain Validation is a software procedure in which a host queries a device to determine its ability to communicate at the negotiated Ultra320 data rate. EEPROM Electronically Erasable Programmable Read-Only Memory. A memory chip typically used to store configuration information, as it provides stable storage for long periods without electricity and can be reprogrammed. See NVRAM. External SCSI A SCSI device installed outside the computer cabinet. These devices are connected together Device using specific types of shielded cables. Host The computer system in which a storage adapter is installed. It uses the storage adapter to transfer information to and from devices attached to the SCSI bus. Host Adapter A circuit board or integrated circuit that provides a device connection to the computer Board (HAB) system. Internal SCSI A SCSI device installed inside the computer cabinet. These devices are connected together Device using an unshielded ribbon cable. Main Memory The part of a computer's memory which is directly accessible by the CPU (usually synonymous with RAM). NVRAM Non-volatile Random Access Memory. Actually an EEPROM (Electronically Erasable ReadOnly Memory chip) used to store configuration information. See EEPROM. PCI and PCIX Peripheral Component Interconnect. A high performance local bus specification that allows connection of devices directly to computer memory. The PCI Local Bus allows transparent upgrades from 32-bit data path at 33 MHz to 64-bit data path at 33 MHz, and from 32-bit data path at 66 MHz to 64-bit data path at 66 MHz. Peripheral Devices A piece of hardware (such as a video monitor, disk drive, printer, or CD-ROM) used with a computer and under the computer's control. SCSI peripherals are controlled through a SCSI Shortened Product Name (host adapter). Intel® Raid Controller SRCU41L User Manual 19
