GLOSSARY
8-Bit Bus – Data is transmitted to expansion slots and other components on the bus only
along 8 parallel data lines.
10Base-T – It is a 10Mbps IEEE 802.3/Ethernet standard that uses unshielded twisted
pair cable specification.
10Base-T supports network configurations using the
CSMA/CD access method over a twisted pair transmission system, up to a maximum of
100 meters in length without the use of a repeater.
16-Bit Bus or ISA Bus – Data is transmitted along either 8 or 16 data lines, depending
on what kind of adapter card is used in an expansion slot. ISA is the abbreviation of
Industry Standard Architecture.
100Base-TX – It is a 100Mbps IEEE 802.3/Ethernet standard that uses UTP cable.
Also called Fast Ethernet, it uses RJ-45 connectors and EIA/TIA T568B pinning.
Maximum cable length from hub to node is 100 meters without a repeater.
Adapter – It is also called an expansion board, expansion card, or adapter card. It is a
small circuit board that is installed in the expansion slots on the motherboard. You can
install a particular adapter that connects a new device such as internal modem, sound
card, or scanner.
AGP (Accelerated Graphic Port) – is a 32-bit, 66MHz external frequency data bus that
transmits data at a maximum of 528MB/s (4 times the speed of PCI transmission); this
design improves the speed of large video transactions.
BIOS (Basic Input /Output System) – This is a chip on the motherboard that contains
the instructions for starting up, or booting, the computer, and more.
Bus – Data that travels in a computer along the circuits on the motherboard are called
buses.
Although three main buses (data bus, address bus, and control bus) manage
the computer's operation, these are often collectively called the bus. The bus carries
instructions back and forth between the CPU and other devices in the system. ISA,
EISA, VL-Bus, PCI and SCSI are examples of PC buses.
