kernel

[Deedra Waters]

I'm currently using the 2.2.19 version of the kernel, I'm using debian,
and would like to update it to a newer version. I'm looking at the website
in another screen and I see two versions of the 2.4.9 kernel
  linux-2.4.9.tar.gz.sign           16-Aug-2001 11:32     1k

and I see this one...
linux-2.4.9.tar.gz                16-Aug-2001 11:32  26.2M

I guess what I'm asking, is which one should I go get, or if not either of
those then what should I go get to update it?
thank you for your time.
