Glossary

Access times. The average
amount of time to access an
item of data.
Analog. (as opposed to digital)
where digital is defined discrete
items which can be reduced to
zero and one bits, Analog is
continuous, so on any graphic
representation of Analog data
there are an infinite number of
points between any two points.
Digital Approximates by adding
data points.
Buffer. RAM Cache that is faster
than the data is being delivered.
Buffers are used so data may be
stored and delivered to the
receiving item as it is needed.
Burn a CD. Recording a CD-R.
Because a laser is used to write
a CD it is also known as burning
a CD.
Burst transfer. The fastest a
device can transfer, usually
from its buffer.
CD-R drive. A drive that can
write to recordable CD-R media.
CD-RW drive. A drive that can
write to recordable CD-R and
Rewritable CD-RW media.
CD-ROM drive. A drive that
can read from CD media.

Data stream. The flow of data
that accomplishes a task, usually
related to moving data from
storage to computer RAM or
between storage devices.
Digital. Discrete information
that can be broken down to
one or zero bits.
EIDE. Enhanced IDE supports
two IDE ports unlike IDE's
single port. Commonly referred
to as IDE.
Host. A device on the SCSI
bus is either a host or target.
The host is also known as
the initiator.
kb kilobyte. Basically this
means 1000 bytes, but is
actually 1024 bytes.
kb/s kilobytes per second.
Means of measuring
throughput.
Kilobyte. See kb
CD-RW Recorder User's Guide
Mb. Megabyte. Basically means
one million bytes, but is actually
1024 kilobytes or 1024 X 1024
bytes which is 1,048,576 bytes.
Mb/s. Megabytes per second.
Means of measuring
throughput.
Megabyte. see Mb
Record a CD. Burn a CD,
Writing a CD. Uses special
CD-Recordable discs which
can be altered by the laser in
a CD-R drive.
SCSI. Small Computer System
Interface. A Standard used for
communication on PCs.
Source hard drive. The drive
which contains information that
will be written somewhere else.
In CD recording, the source
hard drive contains the
information that will be
written to the CD Recorder.
CD-RW Recorder User's Guide
Sustained transfer. The rate
which data can be transferred
from one device to another.
This rate is an average over a
longer period of time than a
burst transfer rate. Because the
sustained transfer test is longer,
it means the testing will take
into account both reading or
writing from the storage
device's buffer, as well as
from the media. Reading and
Writing from the media is a
much slower operation, so
the sustained transfer test is
usually a much better test for
determining the usability of a
device in a real application,
such as recording a CD.
