Data Storage And Transmission Essay

769 words - 3 pages

Analog describes a device or system that represents changing values as continuously variable physical quantities. A typical analog device is a clock in which the hands move continuously around the face. Such a clock is capable of indicating every possible time of day. In contrast, a digital clock is capable of representing only a finite number of times (every tenth of a second, for example). In general, humans experience the world analogically. Vision, for example, is an analog experience because we perceive infinitely smooth gradations of shapes and colors.When used in reference to data storage and transmission, analog format is that in which information is transmitted by modulating a continuous transmission signal, such as amplifying a signal's strength or varying its frequency to add or take away data. For example, telephones take sound vibrations and turn them into electrical vibrations of the same shape before they are transmitted over traditional telephone lines. Radio wave transmissions work in the same way.Computers, which handle data in digital form, require modems to turn signals from digital to analog before transmitting those signals over communication lines such as telephone lines that carry only analog signals. The signals are turned back into digital form (demodulated) at the receiving end so that the computer can process the data in its digital format. With the countless devices that use analog, I don't believe it will be completely eliminated, but with new developments in the industry, no one can accurately make that prediction.Its relatively rapid responsiveness to users and other design attributes distinguish the Internet from other parts of the information infrastructure, such as the public switched telephone network (PSTN) or the television networks (cable and broadcast). The design of those other networks is more focused on the center, and greater functionality is located within the networks. They have been more centrally developed and managed and historically have limited what users can do with them. In contrast, as detailed below, the Internet's design is effectively neutral to what services operate across the network. This enables a relatively unrestricted set of applications to run over it without the need for changes to be made within the network.Although the PSTN architecture is changing in significant ways, there remain considerable differences of approach between it and the various architectural alternatives...
