MP3 players and files have quickly spread throughout all media outlets and have becoming the single most popular format for music. As technology has improved, however, data compression methods and encryption styles have exceeded the capabilities of the MP3 format. To substitute this popular file format with one that is smaller, has better quality, and doesn’t confuse the user, software manufacturers have created the MPEG-4 or MP4 file format. The problem is that some media players that were previously used to play MP3 files have not yet been updated to Read More

The Seebeck Effect was first discovered in 1821. It describes the thermoelectric phenomenon that results when the temperature differences between dissimilar metals in a circuit are converted into electric current. This is one of three similar processes that relate to conductivity, temperature, and thermoelectricity that was discovered in the 1800s. The Thomson Effect was first written about in 1851 following the Peltier Effect explanation in 1834. Who Invented the Seebeck Effect? The effect is named after East Prussian scientist Thomas Johann Seebeck, who lived from 1770 to 1831. He first Read More

This is the “right hand” of both the professional and the amateur lineman. Basically, it is a customized portable telephone which is designed to be hooked onto raw cable terminals in the field and used to monitor the line, talk, or dial out. The monitor function is usually the main difference between the “butt-in” test set and the normal phone. If you don’t have a real test set already, the following circuit can convert a normal $4 made-in-taiwan phone into a working test set. The “all-in-one” handset units without bases Read More

An IFL, or Interfacility Link, is a cable system that is used in facilities to connect an outdoor unit and an indoor unit. An outdoor unit refers to the satellite receiver or coaxial cable that connects a service provider to a company while an indoor unit refers to the coaxial cables, routers, or transmitters inside the building. IFLs are used to minimize the amount of interference received on the transmission by rerouting the signal through a combination of different technologies.   How IFL Works In a typical direct broadcast satellite Read More

A firewall is a software component that restricts unauthorized inward network access. It allows outward information flow. It is set up to control traffic flow between two networks by configured permissions like Allow, Deny, Block, Encrypt, etc. It is normally employed to avoid illegal access to personal computers or corporate networks from external unsafe entities like the Internet. The firewall scrutinizes all the information flowing in and out of the network. If some data do not meet the necessary criterion, it is denied access into the network. A firewall’s key Read More
