if there is no PC2 then what is this?

google PC2 5300 DDR2, there's DDR2 PC5400 too
there's PC2 4200 too

and they are on ebay too.

it does seem to me , - i haven't researched it thoroughly though -
that when ram is specified, so, in the terminology. DDR and PC go
together.
But for DDR2, it can be written with PC or with PC2. Both give google
results.

So , with DDR2, there does appear to be a thing as PC2.. Is it the
same as PC ?
