Here is the comic for the 3rd June. I can see our 1st year programming tutor having a chuckle at this one. Out of pity, if anything. If your not sure you get the joke, then enrol onto a university computing degree and spend 3 years learning the difference. This will turn out to be quite expensive, mind you.
Alternatively, check that internet thing. If you cant be bothered reading up on it, then just laugh really loud to yourself, and for a bonus effect shout “AMERRY-CUNS B DUM!!”
