What this does is expands the possibilities of condition statements so that you can test for more than one value. So you're testing whether the value of an expression is true, or false.
If you're using OR in condition statements only one of the values you are testing as to be true for the given code block to run.
If you're using && or AND in your condition statements, all the conditions you test have to be true for the code block to run.
