LEDs (Light Emitting Diodes) are now found on almost every electronic device including MP3 players, DVD players, TVs, clock radios, and computers. LEDs have been popular for decades. However, today they are cheaper, brighter and come in more colors than ever before. While the incandescent light bulb has been the light of choice for at least 100 years, many believe the LED will soon replace it. Here is how LED light bulbs work. What is an LED Light Bulb? LEDs are very similar to traditional light bulbs, except that they Read More

Audio control software refers to software applications that can play multi-digital formats, giving the user control over the control module’s sound, features, and appearance. Some of the more popular audio control software programs available today are Nullsoft Winamp, SnackAmp, Ecasound, Supercollider, and Microsoft’s Windows Media Player. Nullsoft Winamp Winamp is an audio control software that plays a variety of formats including MP3, MP1, MP2, AAC, WAV, WMA, MIDI, MOD, OGG, Vorbis, FLAC, etc. In addition, Nullsoft’s Winamp plays AVI files including MPEG and NSV (Nullsoft Streaming Video). Besides being able Read More

Organic Light-Emitting Diodes (OLED) are considered by many people as the next step in display technology, with the potential of replacing current plasma or LCD large-screen televisions with ultra-slim, ultra-light screens that can be folded when not in use. They are currently being used in small screen displays such as computer monitors, digital cameras and car TV screens. The next stage of development is to create commercially-viable, large TV screens. LED and OLED In order to understand OLED, one needs to start with the light-emitting diodes or LED. Simply put, Read More

A print spooler is a type of software that manages printing jobs that an electronic printer produces. Print spoolers are often used in industrial and commercial applications in order to place printing jobs in a specific priority level, depending on the time stamp of each job. They are usually used in situations that involve mass printing or printing by many different users. Print spoolers also alert users when their material has been printed, assign jobs to different printers so that multiple materials may be printed simultaneously, automatically select stationary, etc. How Print Read More

Files ending in .daa extensions are movie files specially formatted to facilitate downloading from the internet. Converter software is required to view .daa files. What do you need to know about .daa files? Generally, movie files are in .avi or .mpeg format. When storing movies digitally on CD or DVD, however, it is preferable to use .iso or .bin/.cue format. Although it is possible to send and receive large movie files of this type, their large size means it is a tedious and cumbersome task. One solution is to convert Read More

In the early days of computers, technicians would engage in what is called “component level repair.” Plummeting equipment costs, explosive equipment complexity, and the rising costs of skilled labor has led to an almost complete decline of component level repair. Almost all computer repair is currently done by swapping out parts. Component Level Repair Each part of your computer consists of many smaller components. Your computers monitor, for example, will contain small components such as capacitors, resistors, transistors, and diodes. Most of the time these components will be stored inside Read More

1024×768 is one of the most popular resolutions for PC video screens. The 1024×768 resolution was introduced as an enhancement to the Super VGA (SVGA) standard. 1024 is the horizontal resolution and represents the number of columns supported by the video card and monitor; 768 is the vertical resolution and represents the number of rows (or lines) supported. 1024×768 on the Web 1024×768 was the most popular screen resolution in use by our site visitors for many years. As of 2012, the wider 1366×768 resolution has taken the top spot Read More

Thermal grease cools electrical components and is sometimes referred to as thermal paste. It is most commonly used on computer processors in order to help with the CPU’s heat transfer process, which prevents the computer from overheating. It is a durable and thick substance and is also applied to heat sinks in other electronic equipment, including fans and video card processors. How is Thermal Grease Made? Thermal grease is made from mineral fluid or a silicone base that is mixed with metal oxide fillers. It has high thermal conductivity and Read More

DVI (Digital Visual Interface) cables implement the DVI video interface standard in order to enable high visual quality displays on LCD flat panel and digital projector displays. The Digital Display Working Group (DDWG) created this standard as a succeeding technology to the traditional VGA connection standard. DVI connector technology carries uncompressed digital video and is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in the DVI-D (Digital) mode and with VGA when operating in analog mode (DVI-A). How does DVI Work? The DVI interface uses a digital protocol that Read More

Sempron is a name for AMD's line of lower-cost CPUs. The Sempron line is designed to complete against the Intel Celeron lower-cost CPUs. Sempron CPUs feature a L1 cache with 64KB of memory for data and another 64KB of memory for instructions. The L2 cache on Sempron CPUs operates at the full speed of the CPU and ranges from 128KB to 512KB in size. Sempron CPUs support MMX, 3DNow!, and SSE. Some models of Sempron CPUs also support SSE2. Sempron CPUs are designed to fit Socket-A or Socket-754 CPU sockets.
