Pkzip etc use compression where, yes, data is removed - otherwise it
would
not be compressed!!
BUT at decompression, that data is recovered to create an exact copy of
the
original.
With Jpeg/mpeg2 etc, data is removed that CANNOT be recreated - is this
why
there appears to be some confusion?
BOTH methods do lose data when the file is compreseed, but one of them
can
recover that data.
