SCSI
Small computer system interface. A high-speed interface that can be used to
connect devices to a computer, such as hard drives, CD drives, printers, and

Each device is accessed by an individual ID number on the SCSI controller’s
bus. See also LVD.
SDRAM
Synchronous dynamic random-access memory (DRAM). A type of DRAM used
on DIMMs. SDRAM is synchronized with the computer clock speed,
operating at the same speed as the system bus.

be installed in multiples of two or four. See also DIMM and RIMM.
SMART
Self-Monitoring And Reporting Tool. A standard for developing hard drives
and software systems that automatically monitors a hard drive's health and
reports potential problems. Ideally, this should allow you to take proactive
actions to prevent impending hard-drive failures.
SMBIOS
System management BIOS. A standard method by which the BIOS data of a
WfM-compliant computer can be accessed remotely.
