Any user of e-mail must himself face the newspaper with messages nonwished, that they come from unknown senders, with publicity or apparently normal content. It is the denominated Spam or mail trash, one of the horses of battle of the security in Internet nowadays.
Origin of the term
Word Spam comes from World War II, when it was custom that the relatives of the Soviet and British soldiers sent tin food to them, one of which was with meat and Spam was denominated. Years later, in 1970, the group of British comedians Monty Python created a sketch in which Spam in all the plates was included. From the term one became popular here in computer science as denomination of which you give without to want it you.
Etymological, the term comes from the United States, where the pork butcher company Hormel Foods created in 1937 a tin meat that was called Hormel's Spiced Ham. So Spam arises by the contraction of Spiced Ham.
