A86: Zero Terminated Strings



I have 3 questions about that little 0 that comes after .db's.
 
1. Why is it necessary to stick a ",0" after certain .db strings?
 
2. When is it necessary to use the 0? In some source code it's not always there.
 
3. Does the 0 take up a byte in the program itself or is it just for the compiler?
 
Thanks in advance for taking the time to answer. I appreciate it.
