The is the most common stitch made by most sewing machines. Its created by a top thread locking into a bottom thread.
Chain Stitch.
A chain stitch is created by looping the bottom thread around the top thread. It is less secure than the lock stitch because if one end comes undone the whole stitch will unravel.
Here is a great animation of how both a chain stitch and a lock stitch work.
Double Chain Stitch.
Same as a chain stitch but made with two needles.

Over Lock.
This is used on the edges of fabric to prevent them from unraveling.
Eyelet/Keyhole.
This machine sews the holes for buttons. I have not seen a diagram for this actual stitch but I have a very interesting video of a machine in action.

Bar Tacking.
This stitch is mainly used to attach belt loops and back pockets. The tight zigzag patern of this stitch allows it to hold a great amount weight, up to 400 lbs!
The stitch right above the rivet is the bar tacking.
Lap Seam/Butt Seam.
This is kind of confusing but lap seaming is the how the belt loops are made. There is an actual machine that will trim and align the fabric, sew it shut and cut it to the desired length.
A chain stitch machine uses only one thread, the needle thread. As the animation in your link shows, there is no bottom thread or bobbin.
