Solar energy is created by taking sunlight (solar thermal energy) and converting it into electricity. This conversion takes place via a medium that absorbs the solar energy and then converts it into usable electricity that can power various objects that are electrically operated. While the solar panel is not the most effective method of generating electricity, it remains a favorite because of the unlimited amount of energy that the sun provides. How Does Solar Energy Work? A solar panel is necessary in order to create solar energy. The most widely Read More

Publishing Content using WebDAV You can use Web Distributed Authoring and Versioning (WebDAV) to manage and publish content such as HTML files, ASP pages, scripts and executables, to IIS. You can use WebDAV to create and modify web content on Internet servers. WebDAV utilizes the port 80. This is the default used by HTTP. By default, WebDAV is not installed, nor enabled in IIS 6. How to install WebDAV Click Start, Control Panel, and click Add/Remove Programs. Click Add/Remove Windows Components in the Add Or Remove Programs dialog box. Click Read More

A dual LNB (Low Noise Block-Down Converter) is an LNB system that features two outputs rather than one and allows satellite television subscribers to watch multiple channels on separate television sets simultaneously. Dual LNB systems use only one parabolic satellite dish, but have two cable connections that are connected to separate televisions in the user’s house. When the LNB collects television signals, it splits them into two equal signals that each television receives at the same time. Like dual LNB systems, triple and quadruple LNB systems are also available. How Read More

An AVI (Audio Video Interleave) file is a container format that allows audio and video files to be played simultaneously. Also, because AVI files are file containers they hold subtitles and menu files. AVI files are similar to DVD files but are technically derived from RIFF (Resource Interchange File Format) files. A file known as “codec” can encode or decode AVI files and may contain any other file format including MPEG-4 (MP4), QPEG, MPEG, Realtime, Cinepak, and JPEG. How AVI Files Work AVI files store audio and video data for Read More

Telephone switches route calls through the PSTN (Public Switched Telephone Network). When you pick up the handset on your home telephone, you are initiating a connection with your local telephone switch. When you dial a telephone number, your phone switch interprets the digits you dial and determines where to route your call. If your call is to another number in the same area, your local end-office switch will make the call itself. If your call is to another area, your local end-office switch will route your call to a toll-switch. Read More

Flops is an acronym that describes a unit of measurement known as “Floating point Operations Per Second”. A teraflop measures by trillion floating point operations per second. A variety of technologies can now offer more than a teraflop of power, the most recognizable being servers and desktop supercomputers. Why Teraflops are Useful Teraflops are a large amount of power. High level electronics such as servers must be capable of handling large amounts of information. Handling a large amount of strain, while remaining fast and capable of doing background work, and Read More

In order to understand what a checksum error is, it is important to first learn what a checksum is. A checksum is a redundancy check during a computer’s start up process, which makes sure that the computer’s data is intact and unhampered. The data is scanned and tested for accuracy, either based on how well it relates to data elsewhere or based on previous data that was stored on the same computer. Essentially, all of the bits of data in a particular document or file are added up and a Read More

The Signal to Noise Ratio is a ratio of desired signal to undesired signal (noise) in the average power level of a transmission. The signal is what you are measuring that is the result of the presence of your analyte. Noise is extraneous information that can interfere with or alter the signal. It can not be completely eliminated, but hopefully reduced. If there is too much noise in a circuit, the Signal to Noise Ratio is low. If the circuit is of good quality, the Signal to Noise Ratio will Read More

RADIUS (Remote Authentication Dial In User Service) is a system procedure that offers centralized entrance, approval, as well as accounting administration for individuals or computers to add and utilize a network service. Individuals often need “Authentication” when they try to fix to a network. People have to face far more problems while connecting their computers to a telecommunication network. For example, the telco wants to know the computer operator. When the identification is given, it may ask what services the user prefers. Plus, at that moment, the telco collects billing Read More

The term Artificial Intelligence first saw use in 1955 when John McCarthy (now Professor Emeritus in Computer Science at Stanford University) used the term to refer to the scientific process involved in making “intelligent” machines and computers. McCarthy credits the British mathematician Allan Turing (1912-1954) with the initial efforts to study artificial intelligence, citing Turing’s 1950 article where Turing discussed the terms under which a machine can be considered intelligent. Turing argued then that if a machine can pretend to be human to a well-informed observer, then the machine could Read More
