Please, don't hate me, but I feel the patriotic need to behave like a sort of encyclopedic pest here...
About pasta, in Italy we basically have two different products: dried pasta (we call it just pasta) and fresh pasta (pasta fresca or pasta all'uovo).
Dried pasta (from big large scale producers, like Barilla or Buitoni, and from small producers, which sometimes are more careful about the selection of wheat varieties), which is made with flour made from "grano duro" wheat variety (Triticum durum wheat), grown in southern and central Italy. This is the classic spaghetti, penne, farfalle, and so on kind of pasta.
Fresh pasta is a different product. The difference is not simply in the dry/fresh alternative, but in the fact that it is produced with a softer kind of flour, made from the Triticum aestivum wheat variety, which is grown mainly in northern and, again, central Italy, with or without eggs. The most diffused pasta fresca types we use in Italy are lasagna, tagliatelle, fettuccine and many kinds of filled pasta, like ravioli, tortellini and agnolotti, just to name a few.
However, to add further confusion (we're Italian after all
), we also make home made "pasta fresca" with grano duro, too, for example to make orecchiette (Puglia region), strangolapreti (Naples), cavatiddi (Sicily), malloreddus (Sardinia) and so on. And to drive you mad, you can also find industrial made "pasta all'uovo", which should be pasta fresca, well dried and sold in commercial packages…
Ok, now I’m going to prepare some good old spaghetti all’amatriciana!
