Glossary
100-Base-TX
Twisted-pair variant of 100BASE-X. Uses the physical characteristics of FDDI’s TP-PMD,
but uses Ethernet framing and CSMA/CD. Used in Silicon Graphics Origin and Onyx2
systems.
100-Base-X
100Mbps CSMA/CD 802.3/Ethernet-like LAN also known as Fast Ethernet. There are
two types: 100BASE-TX (used in Silicon Graphics Origin and Onyx2 systems) and
100BASE-T4.
byte
A measure of data. 8 bits. See also kilobyte, megabyte, and gigabyte.
cache
Memory used exclusively by the CPU for temporary storage and calculations.
channel
A specific I/O bus; typically used to describe SCSI bus numbers (for example, SCSI
channel 1).
See also controller.
chassis
The mechanical framework to which components of a computer are attached.
controller
Literally the circuitry (typically an ASIC) that controls a bus or device. Also used to
describe a SCSI bus as a synonym for “channel.”
See also channel.
CrayLink Interconnect
A Silicon Graphics bus technology for linking nodes. See also node.
dual in-line memory module (DIMM)
A module to which are attached SDRAM chips.
