Random numbers are a relative concept. In general, random numbers used in digital electronics are called Psuedo-Random sequences. There is a defined algorithm that is used to generate the sequence and does not actually occur in nature. In applications like Flashing a LED, this method is fine. However, for any level of encryption this is unacceptable. Steve Buch at Electronics Weekly writes about how researchers Dr. Marie O’Neill and Dr. Jiang Wu at the University’s…

Electronic communications systems are made up of three basic components: a transmitter, a receiver, and a transmission medium. Use a video game system with a wired controller as an example. The controller is a transmitter, while the console is a receiver, and the wire that connects the two is the transmission medium. This wire is typically made up of copper. The distance from a couch to your tv is relatively short compared to the distance…
