what is ibdata1

[balaraju mandala]

Hello All,

I need some explanations about these files.

1. ibdata1
2. ib_logfile0
3. localhost-bin.index
4. localhost-relay-bin.000001
5. master.info
6. relay-log.info

is these are standard names. I mean these file names are reserved for mysql?
and can be found, where mysql installed.

regards,
bala
