Hash Functions
	• When two or more items are mapped to the same index after •  using a hash function, a collision occurs. For example, what if our two employee id #s were: 123445678 and 123445779 – ...using the % operator, with a table of size 101...both of these map to index 44. – This means that after we have inserted the first id# at index 44, we can't insert the second id # at index 44 also!
