Answer / jaswanth.saladi

ext2 : It was only the default file sysyem upto 7.1 redhat
version
->less speed,secure and doesnt supports journaling

ext3 : this was from the 7.2 redhat version
->more speed,secure n supports journaling compared to ext2

Journaling : This is one of the default feature of ext3
which provides multipls functions like data avaliability
across improper shut downs,esay transmission between the
file systems and speed etc...
