Therefore, to put songs in order on an iPod, one has to go into the folder where the music is and put them in order. Or, they can create play lists with the songs in order. How to Create a Play list on an iPod The most effective Read More

  Round Trip Time, or RTT, also known as “round-trip delay time” is the time it takes for a signal to be sent from a transmitter to a receiver plus the time it takes to verify that the signal has been received; therefore, Round Trip Time is the time it takes for a signal to be sent from one location to another and back again. RTT almost always relates to telecommunication, but may refer to the Internet, satellite communications, or radar systems.   How Round Trip Time Works Round Trip Time Read More

A radar jammer is a piece of equipment used to scramble nearby radar signals. Radar jammers are often used by drivers to jam the signals coming out from police speed detectors. The radar jammer is very similar to the Power Drainer and is the size of a small box. Radar Jamming as a Crime There are active radar jammers available that work on the principle of interfering with the Doppler shift that is created in the radar beam from the radar gun. However, the law states that the interfering of Read More

There are three primary colors in light that, when mixed together, form other colors. These primary colors in light are green, red and blue. For example, by mixing and matching the different wavelengths of light, someone can take green and red and make yellow. It is this constant mixing of light wavelengths that allows for different colors to appear. Each primary color, when mixed with another primary color, makes a totally different color. The following are the different possible colors that can be made when mixing the different primary colors Read More

Phosphorescence is an effect in which some chemicals re-emit light that they absorb. It is similar to fluorescence, except that the chemical reactions within phosphorescent materials happen less often, thus they take longer to emit light. Phosphorescent materials can be recharged by being exposed to light and may store light for several hours before it is re-emitted. Phosphorescence and fluorescence make up the vast majority of glow-in-the-dark products, with fluorescence generally being used in situations that involve a steady power source and phosphorescence being used in situations that do not.

Substitution and transposition ciphers are two categories of ciphers used in classical cryptography. Substitution and transposition differ in how chunks of the message are handled by the encryption process. Substitution ciphers Substitution ciphers encrypt plaintext by changing the plaintext one piece at a time. The Caesar Cipher was an early substitution cipher. In the Caesar Cipher, each character is shifted three places up. Therefore, A becomes D and B becomes E, etc… This table shows “VOYAGER” being encrypted with the Caesar substitution cipher: Plaintext V O Y A G E Read More
