A virus stays in the body, so once you have chicken pox, it's always there and your body always recognizes it as a disease and fights off any new viruses. The chicken pox virus does reappear as shingles, a very painful skin rash.
The body makes antibodies which it uses to fight off the virus (or bacteria). When the virus has been defeated, some of these special cells (memory cells) are laying in wait until it happens again. Then they can rapidly regroup and attack again.
Once you have been exposed to that virus, your body has memory cells that will respond very quickly. Actually, you can be attacked again but you will not get the disease again because these memory cells will destroy the virus.
