Napster and Gnutella are two types of file sharing systems. Both file sharing systems have many advantages particularly their ability to increase available bandwidth and disk space through the creation of mini-servers off of member computers. Napster Napster was the pioneer of the concept of peer-to-peer file sharing where computer hard drives became mini-servers. This allowed files to be shared directly from one computer to another. Upon activation of the old Napster program and upon log on to the site, a computer becomes a server and the files stored in Read More

CNAM (“Calling NAMe”) is an Intelligent Network (IN) service that displays a caller’s name on a digital readout. It is very similar to caller ID except that both the caller’s name and the calling number are displayed on the receiving end of the phone call. This feature only works if the person or organization being called subscribes to the CNAM feature through their local mobile or TELECOM provider. How does the CNAM Feature Work? The CNAM feature improves on traditional caller ID technology in that it transmits and displays the Read More

Smart cameras refer to the new-generation surveillance cameras with behavior-filtering capabilities; they are linked to software that can help the camera identify suspicious behavior. Thus, the person in charge of security need only look at videos when smart cameras send him an alert. This minimizes lost man-hours on monitoring perfectly normal activities and facilitates timely emergency responses. Behavior Classification Programs There are smart cameras being developed and experimented upon that involves observing, tracking behavior and identifying such behavior as either normal/routine or suspicious/dangerous. They do this with the help of Read More

The computer dates back to the early days of Babylon, circa 300 BC. The Babylonians used the first computing device, the abacus, for simple counting. With the increase in human needs and modernization, the computer (especially its power and speed) has advanced significantly. The computer’s evolution is not the accomplishment of any one person. It is rather the result of numerous inventors’ contributions over an extended time period. Abacus was the first computer used for counting. Papyrus assisted people to document language and numbers. Earlier computers did not have the Read More

Developed in the 1920s by a group of physicists, quantum electrodynamics is the quantum field theory that is employed for electrodynamics. Its general purpose is to describe how matter and light interact with each other. Physicists are able to mathematically describe all different types of phenomena that involve the electrically charged particles that are interacting by exchanging photons. Because quantum electrodynamics has been known to provide tremendously accurate predictions – especially in cases of the anomalous magnetic moment of the electron – that one physicist referred to quantum electrodynamics as Read More
