Kristy,
Netscape introduced interlaced GIF graphics as a means of "virtually"
speeding the transmission of GIF graphics, where an
immediate low-resolution image is loaded with the text content of the page,
then the low-resolution proxy is gradually updated
in four passes until the full-resolution GIF images is displayed. This
gives the user a quick impression of large graphics as they
download, and also give the user almost immediate access to text and
hypertext links on the page.
A non-interlaced GIF graphic is one that does not load in that fashion.
Generally, the image is displayed in small increments, as they come
completely through. There really is no "better", it is merely a matter of
personal choice. You may prefer an interlaced image, since some people get
nervous if a large image is loading and it takes a while. A lot of new
people to the net may think it is "stuck" and become impatient (as well as
some of us seasoned veterans ;)) and may hit the "back" button if nothing
is visible after a few seconds. I tend to mix them up about half-and-half.
For a demonstration, check this out:

Hope this helps somewhat. :)
Please feel free to contact me for further assistance.
