Both are basically a way to store data. Arrays are listed in numerical order, 0.. size_of_array. You retreive an element with 
my $val = $array[$number];

It is often desired to retreive the data by a name, instead of a number, so hashes are used. They are often called linked-lists in c. There are 2 lists, the keys and the values, so you can access data with $hash{$key_name}. Hashes are very convenient, but are slower. That is it in a nutshell.
