Your question should be stated:
What is the difference between fraud and deception?
Fraud is primarily a legal term, used mostly by lawyers and courts. To explain it requires some advanced vocabulary, but basically it is:
>> An intentional false representation of fact(s) — by words, by conduct, or by concealment of what should have been disclosed — that deceives another individual, causing that individual to act upon it to his or her legal injury.
Deception is a more general term.
All fraud involves deception, but not all deception is fraud.
Examples:
A company sells you some land. After signing all the required paperwork and paying the money, you discover that the land is actually owned by another person, and the company showed you a false deed to the land. That company has committed fraud -- they intentionally misrepresented themselves as a legal seller and provided you with false documents, and then disappeared with the money you paid. You have been legally injured.
If a guy tells his girlfriend he is too tired to see her that night, and she then discovers he was out with someone else, she was deceived by him. She might use other terms -- he lied, he cheated -- but they are just the more commonly used words for the same thing: deception. An important difference from fraud is that she was not LEGALLY injured.
(Note that you may see "fraud" used in older novels or movies, where someone exclaims, "You, sir, are a fraud!" -- to express how that person misrepresented himself. But the word is rarely used that way in current spoken English. Today, we just call the guy a liar!!)
In summary, we can say that there are very strict legal requirements to prove fraud in a court of law. Most of us will live our whole lives without ever being victims of fraud.
On the other hand, we are all deceived in small ways almost everyday, in personal relationships, family relationships, by store salespeople, product packaging, product advertising, etc. etc.
