There are some specific computer crimes. Some of them include:

Spam – This refers to sending of bulk emails to people’s addresses without their consent or authority usually for commercial purposes.

Fraud on the other hand refers to misrepresentation of facts with the intention of inducing another into doing or refraining to do a particular action which results into a loss. Fraud is committed in a number of ways. The first one is alteration of computer input which is common as it does not require much expertise. This involves use of processes that are unauthorized, entering wrong data or using instructions that are not authorized. The second manner in which fraud is committed is more technical and involves concealing commission of unauthorized activities. This is done by stealing, alteration or damaging the output. This is very difficult to detect and can go on for a very long time.
