What is a Screensaver? A screensaver is an animated image that is displayed on an inactive personal computer screen once user inactivity has been sensed for a certain period of time. Screensavers were originally supposed to prevent burn-in (i.e. the burning of an image into the phosphor inside the cathode ray tube after hours of the same image being displayed). Windows Vista comes with its own built-in screensavers that you are able to select from. You can also find many screensavers that you can download from specific sites. A good Read More

IPTV is an acronym for Internet Protocol TV. It essentially is a technology that delivers video or TV broadcasts over the Internet. Instead of receiving television or video over the broadcast waves, cable lines or through a satellite TV service, your TV is hooked directly into a broadband Internet router and receives digital signal directly over the Internet. Many analysts have stated that IPTV is definitely the trend for the future of television broadcasts. Many broadband operators, telephone companies and cable companies that already pipe in broadband Internet to homes Read More

Portable Document Format (PDF) is a type of file format developed by Adobe Systems. It was first introduced in 1993 and is capable of capturing content and formatting information from any document; irrespective of the hardware and operating system platform. It was initially a proprietary file format; however PDF has been available as an open format from 2008 and adheres to the ISO/IEC 3200-1:2008 standard. The current PDF version is 1.7 Extension Level 3. PDF documents require PDF viewing software such as Adobe Reader, Xpdf, Foxit Reader, Evince and so Read More

When there is a set number of bits associated with a computer CPU, that number refers to the total number of bits that the processor can use or transmit at once. For computer microprocessors, the number of bits also indicates how wide the computer registers are. 64 bit CPUs can address and process data that is represented by 64 bits as a result. When 64 bit computers were first released, a common issue that arose was the lack of 64-bit software that could take advantage of the new features available Read More

A smartphone is a mobile phone with a considerably greater amount of functionality than an ordinary mobile phone or a feature phone. Smartphones can be considered a blend between a mobile phone and a full featured mobile computer, similar to the PDAs (Personal Digital Assistants) of the past, but even more capable. They typically include a complete operating system, the ability to add or remove applications at will, significant amount of data storage, mobile and Wi-Fi internet connectivity, a multitouch capable touch screen, GPS navigation, and of course, standard mobile Read More

Java bytecode is produced by the Java compiler and executed by the JVM (Java Virtual Machine). Java bytecode isn’t exactly source code, and it isn’t exactly compiled code, it’s something in the middle. Java bytecode is one of the things that make it possible for Java code to run on many different platforms.            

RAID (Redundant Array of Independent Disks) is a data reliability and redundancy system that allows data to be stored on multiple computers at the same time. RAID technology is generally used in industrial, commercial, and government computer networks to store copies of system and user files on multiple hard drives that are connected through a logical unit and the network. RAID technology allows companies, agencies, and other institutions to ensure that important files are never lost or that system files that maintain an online server or physical computer network are Read More

An ultracapacitor are a type of electrochemical capacitor that has an incredibly energy density. Known as electric double-layer capacitors, ultracapacitors are able to last much longer than normal batteries and therefore, can continue providing a charge for an incredible amount of time after a normal capacitor or battery would have died out. Why Use an Ultracapacitor? One of the big issues with the hybrid car industry is that they have a large battery inside of them. This is beneficial because it doesn't use as much gasolone; however, these batteries don't Read More

Potassium is an essential mineral that the body uses to perform various functions. The body naturally regulates the amount of potassium in the body to keep it in working order. This is done by the kidneys, the bowels and even natural processes such as sweating. Eating a diet which incorporates the recommended amount of potassium supplementation is best to keeping the body healthy. Improper amounts of potassium in absence or excess can lead to serious problems and even death. It is important to ensure that potassium levels are kept at optimum levels. Potassium and Cell Read More
