A multimedia database is a database that hosts one or more primary media file types such as .txt (documents), .jpg (images), .swf (videos), .mp3 (audio), etc. And loosely fall into three main categories: Static media (time-independent, i.e. images and handwriting) Dynamic media (time-dependent, i.e. video and sound bytes) Dimensional media (i.e. 3D games or computer-aided drafting programs- CAD) All primary media files are stored in binary strings of zeros and ones, and are encoded according to file type. The term "data" is typically referenced from the computer point of view, Read More

The major types of satellite dishes include motor-driven dishes, multi-satellites, VSAT, and ad hoc satellites. Other types include DTH, SMATV, CABD, automatic tracking satellite dishes, and big ugly dishes. A motor-driven satellite dish is mounted on a pole which rotates around an axis to detect and receive various satellite signals in the sky. It is driven by a stepper motor, which can also be controlled to face any satellite position in the sky. It’s standards, DiSEqC, USALs, and 36v positioners are supported by many receivers. DiSEqC stands for Digital Satellite Read More

DVD is short for ‘Digital Versatile Disc’ and it is an optical disc storage media format that is capable of storing large amount of data. DVD benchmarking tools are used to analyze the quality of the disc. Both the audio and the video quality of the disc are tested with the DVD benchmarking tools and a quality score is usually provided at the end of the test. The quality score can be used for comparing quality of the DVDs. DVD benchmarking tools carry out a number of tests to determine Read More

For computer users that multi-task or work with high performance applications, you should know about virtual memory and how to get the most from it. Virtual memory can be best described as simulated RAM. If your computer has 1 GB of RAM and you use up all of this memory with the OS and several applications, your computer is forced to compensate by switching from physical RAM to virtual memory. Without virtual memory, once your computer ran out of physical RAM, no other programs or higher performance could be possible. Read More

When dealing with a wet phone, it is important to act quickly. Few phone companies offer a warranty on wet phones and have gone as far as to place a "wet strip" on the phone that changes colors when it has gotten wet. What this means is that the wet strip will allow the company to know that the phone was damaged by water and therefore, they don't have to give you a new phone. Fortunately, if you act quick — which happens to be the first and most important Read More

Holographic memory is a storage device that is being researched and slated as the storage device that will replace hard drives and DVDs in the future. It has the potential of storing up to 1 terabyte or one thousand gigabytes of data in a crystal the size of a sugar cube. Brief History of Holographic Memory Using holograms as memory storage was first proposed by Pieter Heerden in the 1960s. During the early 1970s, a group of scientists from TRCA laboratories succeeded in storing 500 holograms using an iron doped Read More

Read-Only Memory or ROM is an integrated-circuit memory chip that contains configuration data. ROM is commonly called firmware because its programming is fully embedded into the ROM chip. As such, ROM is a hardware and software in one. Because data is fully incorporated at the ROM chip's manufacture, data stored can neither be erased nor replaced. This means permanent and secure data storage. However, if a mistake is made in manufacture, a ROM chip becomes unusable. The most expensive stage of ROM manufacture, therefore, is creating the template. If a Read More
