How can you crack something?

Question

Lets just say for an end of year prank i want to do something at school my school is elementary low security and has its own tv system (meaning the schools anounsments are on the school's tvs so how can I break that signal and put something stupid like sesame street on that channel anonymously just for laughs

Answer 1

Firstly what you propose to do is illegal and there are severe penalties for 'hacking'.

Secondly although you consider it a 'laugh' you could cause considerable damage to the system which could be expensive to repair.

Thirdly if you knew how to do it so would everybody else who may play more malicious 'pranks' and infect the system with viruses.

Finally all computer input is traceable so they would be able to identify you and you would be kicked out of school.

My advice is to think of something else that is harmless and a little less of a stupid idea than what you are proposing.
