The DirecTV Single Wire Multiswitch (SWM) is a specially designed piece of hardware that allows a DirecTV satellite dish signal to be split and used with many different tuners/receivers. The usual configurations allow 5, 8, 16, or 32 connections to a single satellite dish. DirecTV SWM is useful because of the satellite dish’s previous configurations, …
Satellite receivers come in standard, HD tuners, DVR, or FTA formats. In a standard receiver, the digital broadcast signal is decoded and presented in the television in an analog format. Most satellite receivers feature an Electronic Program Guide (EPG), which contains a list of the available channels and programming. HD Receivers Made for high-definition satellites …
The Physical Layer is the lowest layer in the OSI (Open Systems Interconnection) Model of computer networking and is used to transfer electrical signals that represent data from one place to another. While the Physical Layer does not represent data itself, it does provide a means for that data to move. Essentially, the Physical Layer …
Computer programs or applications commonly have one or more processes that are executing to support the program. These processes are instances of the running application and may have one or many Operating System threads dedicated to receive computer resources. Each program thread may execute any portion of the process code depending on the program design. …
The Peltier effect is one of the three separately identified effects to which “Thermoelectric Effect” or simply, “Thermoelectricity” refers. The other two are the Seebeck and Thomson effects. Discovery This effect is named after French physicist Jean-Charles Peltier, who discovered it in 1834. Peltier found that the junctions of dissimilar metals were heated or cooled …
A dual core processor is part of a category called multi-core processors. These computer processors have more than one independent processor on the chip or package. In the case of a dual core processor, the entire chip has two independent computer processors that can work together to increase total computer performance. For non-technical consumers, dual …
Electroluminescence is the phenomenon where a material emits light when electricity is passed through it. It is one of the greatest discoveries of the twentieth century and other forms of luminescence, including incandescence, chemiluminescence, cathodoluminescence, triboluminescence, and photoluminescence rival it. Electroluminescence generally involves a material producing light without producing heat. It is different from black …
A power converter is a power supply unit (PSU) that not only delivers energy to an electronic device from an electrical outlet, but also regulates the current to meet the devices specific requirements. If you have any type of sophisticated electronics such as computers, laptops, high end audio equipment, cell phones etc, the odds are …
It is becoming more common every day for various organizations to block access to websites for either security or productivity reasons. As a result, end-users will often find themselves in need of figuring out how to unblock websites. By unblocking a website, the action of obtaining or gaining access to a website that is currently …
A multimeter is used to take measurements of electrical properties for a circuit such as the voltage, current, or resistance. A modern multimeter combines the abilities of legacy voltmeters, ohmmeters, and ammeters. Some of the uses of a multimeter include electrical testing on electrical power sources, motors, and other electrical circuits or components. They are …
