So what does cryptography mean? cryptography: It is the study of encryption, the art/science to create and use codes and/or ciphers with the purpose of enciphering as well as deciphering. After a relatively vivid but slow development of cryptography for nearly 4.000 years the inventions of the telegraph, radio and computer had a high impact on the velocity of further inventions concerning encryption. Most of the time economic, political or military reasons lie behind the necessity of encryption. As visible from the timetable cryptography it is also done for private and individual interests. An extraordinary example for this is the Braille Code, developed as a possibility for blind people to read and write. A lot of very interesting and intelligent websites about cryptography can be found in the Internet.Some websites offering links to various cryptography-websites are: Further there exists a wide range of web-magazines/newsletters/mailing lists on cryptography, e.g.: Crypto-Gram Newsletter: Journal of Computer Security: Cypherpunks: Stegano-L: ZD Internet Magazine: |

World Wide Web (WWW) Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents.

There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes According to the Internet domain survey of the |
