Video RAM (VRAM) is a type of RAM used to store data related to images and videos that a computer’s monitor displays. Generally, Video RAM is stored on the computer’s DRAM (Dynamic Random Access Memory) and reads like any other data before it is translated into display content. Video RAM is used as a buffer between the computer’s processor and monitor, allowing it to process data faster and display content without delay.   How Video RAM Works Video RAM stores images and video frames that the computer’s processor has identified Read More

It is a well-known fact that most computers are susceptible to hard drive crashes or virus attacks. Backing up information is a practical and necessary precaution to protect one's data from being lost forever. There are several realistic methods for backing up data. The best backup method for your data depends opon many factors, including: the importance of the data, the amount of data to be backed up, and the funds available for backup. Here are some of the most commonly used data backup solutions. Flash Memory Flash memory, also Read More

UCleaner is a program that should be kept off of the PC for security reasons. This program advertises as a privacy protector and anti-spyware program, but this is false. The program also goes by the name Ultimate Cleaner, and it is a scam program. The program advertises a free scan of the PC for security risks, and then the security alerts start popping up and there are numerous privacy threats listed in the scan results that do not exist. This is a scare tactic to get consumers to buy the Read More

With the expanded use of 3G and 4G wireless technologies over the past several years, the popularity of Internet radio has continued to increase. Not only can one listen to their favorite radio station(s) at home or work on the computer, but now they can also be accessed through Internet-enabled smart phones. Internet radio differs from on-demand video or music casts in that the programming is streamed live but does not have the ability to be paused like on-demand services. Internet radio also differs from podcasts in that it does Read More

Mfehidk.sys is a system process that runs in the computer background and maintains the Host Intrusion Detection System for McAfee Anti-virus. It is essentially a real-time shield and detects malicious software as it runs on the computer before it has a chance to cause significant damage. Mfehidk.sys is also known, however, for slowing computers down and even causing the BSOD (Blue Screen of Death). Mfehidk.sys can be found in the Drivers subfolder of the primary hard drive’s System32 folder.   How Mfehidk.sys Works Mfehidk.sys works in the same way that Read More

Wavelength Division Multiplexing (WDM) is a technology found in fiber optic communications. WDM uses a single fiber to transmit multiple optical signals. It does this by breaking up the signal into different frequencies or wavelengths of color. The various wavelengths indicate that different amounts of data are being transmitted simultaneously. This results in an increase in capacity and allows bidirectional communication over any single fiber. That is to say, the fiber can have a signal going in one direction and another going in the opposite direction. How WDM Works For Read More

Elasticity and conductivity are often mutually exclusive in industrial materials, making it difficult to find a material that one could twist and bend and use for electric conduction at the same time. Electrical wires, often made out of copper or some other metal stretched out into threadlike widths, were invented to try and bridge the gap but was impractical if one wished to apply them to a surface. Metals are also highly reactive to chemicals and this is a problem if one wanted to use them for everyday purposes. As Read More

DVI (Digital Visual Interface) is a video connector designed by the Digital Display Working Group (DDWG), aimed at maximizing the picture quality of digital display devices such as digital projectors and LCD screens. It is crafted for transporting uncompressed digital video information to a display screen. It is partly compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A). DVI Vs. Older Video Technologies Previous standards such as Video Graphics Array (VGA) were designed exclusively for CRT-based devices and hence did not Read More

Nanopollution refers to the waste matter or byproducts of nanoscopic device or material manufacture. Nanoscopic device or material manufacturing processes leave behind nanoparticles (smaller than a billionth of a meter) which can infiltrate the cells of humans, animals and all living organisms that may be unprepared for the influx of artificial particles. A 1941 study from Johns Hopkins Hospital discovered that nanoscopic particles, when inhaled, could make their way into the brain via the olfactory tract. This raises some concerns about the possible health risks connected to the recent developments Read More
