In brief: Monitoring Centers

Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food.
Lymph nodes "taste" the lymph for anything bad like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.

In brief: Many things

Generally these enlarged nodes are in response to upper respiratory tract infections.
If they remain soft, non-tender, mobile and do not increase in size they should gradually resolve in time. If they are behind the muscle from the angle of the jaw to the area around the notch in your breastbone (sternocleidomastoid) this is generally viral, but all bets are off. Could be anything.
