Computer Terminology

Electronic Spam, commonly shortened and called "Spam," is a general abuse of online messaging systems, including instant messaging, email, etc. Spam is most commonly associated with email spam and is defined as a constant stream of nearly identical emails indicating a single point, e.g. advertising.

• Spam is the abuse of electronic messaging systems to send unsolicited bulk messages indiscriminately. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, Online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, and file sharing network spam.

  Spamming remains economically viable because advertisers have no operating costs beyond the management of their mailing lists, and it is difficult to hold senders accountable for their mass mailings. Because the barrier to entry is so low, spammers are numerous, and the volume of unsolicited mail has become very high. The costs, such as lost productivity and fraud, are borne by the public and by Internet service providers, which have been forced to add extra capacity to cope with the deluge. Spamming is widely reviled, and has been the subject of legislation in many jurisdictions.

• Electronic junk mail or junk newsgroup postings. Some people define spam even more generally as any unsolicited e-mail. However, if a long-lost brother finds your e-mail address and sends you a message, this could hardly be called spam, even though it's unsolicited. Real spam is generally e-mail advertising for some product sent to a mailing list or newsgroup.

  In addition to wasting people's time with unwanted e-mail, spam also eats up a lot of network bandwidth. Consequently, there are many organizations, as well as individuals, who have taken it upon themselves to fight spam with a variety of techniques. But because the Internet is public, there is really little that can be done to prevent spam, just as it is impossible to prevent junk mail. However, some online services have instituted policies to prevent spammers from spamming their subscribers.

Depends on several factors:

• number of bytes per character: 1 to 4 depending on which alphabet and character encoding you use. 1 byte per character for US-ASCII and the most common Western Europe encodings.
• length of the string: bytes per character times number of characters
• programming language: in C, the string takes up no more space than the characters do. In many other languages, there is an additional fixed overhead for the string object itself. For example in Java, a string takes 2-4 bytes plus the space taken by the characters.
