after the great fire in Rome in 64 A.D. threw suspicion for having started it on the
Christians. The suspicion that Nero himself started the fire cannot be proved, but
it indicates what his citizens thought he was capable of. However, there was no
real systematic persecution of Christians, since the events which took place were
restricted to the city of Rome. After the failure of plot against Nero hatched in the
Senate and lead by Piso, repression increased. Uprisings in Gaul, Spain and
Africa caused the Praetorian Guard to withdraw its allegiance to Nero. The Guard
then declared its support for Galba as emperor and the Senate declared Nero to
be hostis populi Romani (an enemy of the Roman people), upon which he
committed suicide. His death marked the end of the Julian-Claudian imperial
dynasty.
On the fly
This is a write process which does not involve storing the data to be written to the
CD on the hard disk first. The data is written directly onto the blank CD. Another
term used for on the fly is "fast copying".
Packet CD / Packet writing
This is a write process which involves sending the data in blocks to the CD-RW
drive without first creating an image file. The CD-RW drive is used in the same
way as a hard disk or floppy disk, which means that any application can write the
data to the CD. CDs created using packet writing can only be read with a special
UDF driver.
PCM
PCM is the main standard for digitizing audio files and speech. PCM stands for
pulse code modulation and involves digitally encoding analog signals.

This is also referred to as a pause. It is the area on a CD which separates one
track from another. In Nero the default pause is set to 2 seconds (Red Book
standard).
Session
CDs are divided into tracks and sessions. A session consists of all the files which
are written to the CD in the course of one write process and can consist of one or
more tracks. There can be more than one session on a multisession CD.
Simulation
Simulation corresponds to the process of writing data, except that no data is
written. Simulation is used to check whether the data can be sent to the recorder
quickly enough to avoid a buffer underrun. It can also be used to check whether
the recorder can actually write to the CD. You should use simulation when you
are not sure whether the system can send the data quickly enough. If you have
already burnt a few CDs successfully, you can switch off simulation. If your
recorder has a buffer underrun protection function, you do not need to use
simulation.
