Text scaling

Question

My knowledge on vectoring is not good, and I think this is the issue.  But need some help trying to understand text.  I understand that it's bitmap based not vector and therefore can become pixelated if text is reduced/enlarged.  I've heard (correct me if I'm wrong) that text can be vectored in potoshop (like Illustrator) so that the document's text will come out razor sharp at whatever size the document is printed at.  If so, how do I do this exactly?
Thanks

Yes I understand it's fully scalable until you Save it (is this what Rasterize means?), but what is the point of photoshop then converting it to bitmap, is there anyway the vector text can be maintained upon saving, because the quality reduces as soon as you save, or should I be looking at Illustrator to do the text properly?
Rasterize is an option in the Layers drop down menu... it converts a vector object to a bitmap object. (In this case, your text.)You may need to do this – rasterize – for several reasons, including using certain filters or creating certain effects. If you don't need to rasterize the text, leave it as it is.
As long as you don't convert the text layer by rasterizing, it will remain a vector and stay editable (and infinitely scalable) no many how many times you save the file as a PSD (Photoshop file). The moment you save as a .tiff, .jpg, etc the text gets rasterized and as no longer editable in that file.
Hope that explains it....
