Companies, Services, Equipment, Technology, Business Telecommunication is the technique of transmitting a message, from one point or place to another with the typical additional attribute of being bi-directional. In practice it also recognizes that something may be lost in the process; hence the term 'telecommunication' covers all forms of distance communications, including radio, telegraphy, television, telephony, data communication and computer networking. Physics (from Greek from φυσικός (phusikos): natural, from φύσις (fysis): Nature) is the science of Nature in the broadest sense. Physicists study the behaviour and interactions of matter and radiation. Theories of physics are generally expressed as mathematical relations. Well-established theories are often referred to as physical laws or laws of physics; however, like all scientific theories, they are ultimately provisional. The Magical Mystical Crypto-Primer - Cryptography as a security tool Okay, some of you out there know generally what cryptography is supposed to do, how it is used, and what its limitations are. A lot of you probably even have a really good grasp of the mathematics involved. This primer won't tell you people anything you don't already know. Basically, I'm writing this for the cipher-newbies out there that have never used cryptography, or "crypto," and have no idea how it works, and like the idea of starting at the bottom. Phreaking is a slang term for the action of making a telephone system do something that it normally should not allow. It is an illegal activity, but one formerly pursued by a large number of computer and electronics hobbyists out of curiosity. Other reasons why many people attempted (or succeeded in) phone phreaking during the 1960s and 1970s included the (then) very high cost of long-distance telephone service, and a desire to rebel against the AT&T telephone monopoly.
