Dword

 

A double word is a group of four consecutive bytes or characters that are

 

 

 

stored, addressed, transmitted, and operated on as a unit. The lower two

 

 

 

address bits of the least significant byte must equal zero in order to be

 

 

 

Dword aligned.

 

EEPROM

 

Electronically Erasable Programmable Read Only Memory. A memory

 

 

 

chip typically used to store configuration information. See NVRAM.

 

EISA

 

Extended Industry Standard Architecture. An extension of the 16-bit ISA

 

 

 

bus standard. It allows devices to perform 32-bit data transfers.

 

External SCSI

A SCSI device installed outside the computer cabinet. These devices are

 

Device

 

connected in a continuous chain using specific types of shielded cables.

Fast-20

 

The SCSI Trade Association (STA) supports the use of “Ultra SCSI” over

 

 

 

the term “Fast-20”. Please see Ultra SCSI.

 

Fast-40

 

The SCSI Trade Association (STA) supports the use of “Ultra2 SCSI”

 

 

 

over the term “Fast-40”. Please see Ultra2 SCSI.

 

Fast SCSI

 

A standard for SCSI data transfers. It allows a transfer rate of up to

 

 

 

10 Mbytes/s over an 8-bit SCSI bus and up to 20 Mbytes/s over a 16-bit

File

 

A named collection of information stored on a disk.

 

Firmware

 

Software that is permanently stored in ROM. Therefore, it can be

 

 

 

accessed during boot time.

 

Hard Disk

 

A disk made of metal and permanently sealed into a drive cartridge. A

 

 

 

hard disk can store very large amounts of information.

 

Host

 

The computer system in which a SCSI host adapter is installed. It uses

 

 

 

the SCSI host adapter to transfer information to and from devices

 

 

 

attached to the SCSI bus.

 

Host Adapter

A circuit board or integrated circuit that provides a SCSI bus connection

 

 

 

to the computer system.

 

Internal SCSI

A SCSI device installed inside the computer cabinet. These devices are

 

Device

 

connected in a continuous chain using an unshielded ribbon cable.
