Answer / jithesh p
ext 2 & ext3 are the two file systems in linux.ext 2 will
take more time while logon the system. this is bcoz ext2
will check all harddisk peripherals at the time of switch on
your sytem. But ext3 is less time consuming,bcoz instead of
checking all harddisk peripherals it will check only the
bootloader peripherals.

Answer / its.kitts
ext3 is the advanced version of ext2
ext2+journaling=ext3
this journaling feature is very much useful while
retrieving data and writing data into a File System
Latest versions of all Linux flavors are coming with ext3
compatible file systems.

Answer / shshikanth soppa
Availability
Integrity
Speed

In ext2 filesystem, the filesystem is not mounted until its
consistency is checked by e2fsck program. the amount of time
taken to run e2fsck program is determined by the size of
file system. The more files you have on the file system, the
longer the consistency check takes.
ext3 does not require a file system check even after a
unclean shutdown. the time to recover an ext3 file system
after an unclean shutdown does not depend on size, rather it
depends on size of "journal" used to maintain consistency.
the default journal takes about a second to recover.

ext2 means second extended file system .To start up booting

ext3 means third extended file system.it is journaling file
system so data is retrieve while crashing disk as well
booting is fast for starting
