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

Data types in the Java programming language are basically divided into two groups – primitive data types and object references. A primitive data type is a basic building block and has full built-in support. Many other languages also support composite data types, which are build on a combination of primitive data types and may or may not have built-in support. Java Primitive Data Types Let’s discuss the available primitive data types in Java. There are 8 primitive data types in Java, which are Boolean, Char, Byte, Short, Int, Long, Float, Read More

Advanced Audio Coding (AAC) is a standard compression and encoding format for digital audio. AAC is part of the MPEG-4 standard, which was established by the Moving Pictures Experts Group (MPEG), the committee that developed the MPEG-1 and MPEG-2 standards that are used all over the world in CD-ROM and DVD discs and other technologies. AAC is similar in many ways to the popular MP3 format. The encoding and compression techniques are designed in such a way that some information is discarded because of limitations of the human ear.
