KB /s
Kilobytes per second. A means of measuring throughput.
Lead In--Lead Out
These are lengths of track before the beginning and after the end of the coding of a CD track.
In single- session applications, where they serve as 'markers', the lead-in provides
information such as the Table of Contents. The lead-out may include a special code to stop
the CD player. CD-Audio tracks (songs) use lead-in and lead-out to help song selection.
MB (Megabyte)
Basically means one million bytes, but is actually 1024 kilobytes or 1024 x 1024 bytes, which
equals 1,048,576 bytes.
MB /s
Megabytes per second. A means of measuring throughput.
Medium
Physical material, such as paper, disk or tape used to store computer data.
Mixed Mode Disc
A Mixed Mode CD is a CD that contains CD-Digital Audio and CD-ROM tracks. Usually, the
CD-ROM data is recorded in the first track. The audio portion of the CD uses the remaining
tracks (up to 98 ).
Session
A recorded segment of a CD that may contain one or more tracks of any type (data or audio).
In data recording, there is usually only one track per session. In audio recording, all audio
tracks are contained in a single session. A lead-in and lead-out are recorded for every
session on a CD.
Storage
In computers, any equipment on/in which information may be kept. PCs generally use disk
units and other external storage media (diskettes, CD-ROMs, magnetic disks, etc.) for
permanent storage of information.
