You can find more than you need to know, including illustrations, online, but briefly:
Clinchers are like car tires--"regular" tires, open on the inside (the part that faces the wheel) with wire or Kevlar strips called "beads" that hook onto the rim. Nearly all clincher bike tires need inner tubes to hold the air in, and the air pressure pushes the beads outward and holds the tire on the rim.
Tubulars, also called sew-ups, don't have an open side--they're shaped more like doughnuts, or like an inflated inner tube. They mount on a different type of rim (it doesn't have the ridges that engage the bead on a clincher) and are held on by glue.
Tubulars are supposed to be lighter and feel more responsive, and for all I know, they are--I've never used them. But they're harder to repair, because you have to take them off the rim, cut the thread that holds them together, make the repair, then sew them back together, reglue them and wait for the glue to dry..
Clinchers are usually heavier (some good ones are only a little heavier), but they're easier for a novice to mount and easier to patch--you can often just pop in a new tube, pump and ride in three or four minutes, and a patch on the tube takes only a minute or so.

You can do a search on this site. The topic comes up every 2-3 weeks. You will see pictures, explanations, and enough pro and con arguments to choke a horse.
