Difference between black box and white box testing

There are many differences  between black box and white box testing. White box  testing is nothing but where you test each line of software code otherwise in black box testing you just able to test the outlook and out function of the software. Though these two types of testing use for different purposes but you need to know the difference to be a software testing engineer.
