Blue Book
This is the standard for CD's that are created in the CD-Extra and CD Enhanced
format.
Bootable CD
Booting means that the operating system is loaded on your computer. Under
normal circumstances, your PC boots from the hard drive. If you need to boot from
something else besides your hard disk for any reason, you can boot from a floppy
disk or CD. Special “bootable CD’s” must be produced to be able to boot from your
CD-ROM/CD-R/RW drive.
Bridge Disc
A CD-ROM which can be read by a normal CD drive as well as by CD-I devices. It
is specified in the White Book. An example of a Bridge Disc is the Photo-CD.
Buffer
Memory built into your CD-Rom or Burner that temporarily stores information.
Buffer Underrun
Buffer underruns are caused when there is an interruption to the flow of data to the
internal buffer of the burner. This is can be the fault of the software or the hardware
itself. When recording, data is fed continuously to the burner’s buffer in order to
keep a steady flow of data which is required when recording. When something
interrupts that steady flow, it can cause a buffer underrun and your disc is no
longer useable.
Cache
A fast intermediate or buffer memory which is applied at many different areas in a
computer system. With Nero, cache memory is used to store files in buffer from
drives which cannot be accessed quickly enough in order to ensure that the writing
process continues without interruption.
Caddy
A special plastic housing used to protect the CD. The CD is inserted into the drive
in the caddy.
CD-DA (with the extension .CDA)
The acronym for Compact Disc - Digital Audio, this is the first standard for an audio
CD. An audio CD is comprised of several audio tracks whereby generally, one
track corresponds to one song. Each track is additionally sub-divided into sectors.
Music CD’s generally make up this category.
CD-Extra/Enhanced Music CD:
CD Extra is the latest standard for audio CD’s and with a multi-media component.
A disc in this format always has two sessions. The first session only contains pure
audio data which can be played on an audio CD player while the second session
