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

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

A voice changer is exactly what the name states; it changes the sound of your voice. In addition, many voice changers can go further than just changing the sound of your voice, many voice changers can change the gender of a voice (for instance, from female to male) and enhance the voice in many different ways. Types of Voice Changers There are three main types of voice changers, stand alone electronic devices that you speak into, devices that integrate with telephones and software based voice changes that can easily manipulate Read More

Digital media players are hardware devices that are designed to receive data from a source to be streamed and viewed/heard through a television or sound system. The hardware processes the signal in one of two ways: Wired Network – Some digital media players connect to the network through a wired connection. An Ethernet connection to a router is necessary to allow access to files on a PC or Network Storage location such as a server or hard disk that is set up through the digital media player. Wireless Network – Read More

SVGA is an acronym for Super Video Graphics Array and covers a wide range of computer display standards used in the manufacture of computer monitors and screens. The SVGA standard was designed by VESA, the Video Electronics Standards Association. When using SVGA as a direct comparison to other display standards such as XGA (Extended Graphics Array) or VGA (Video Graphics Array) the standard resolution referred to as SVGA is 800*600 pixels. When the SVGA standard was first defined it referred to a resolution of 800*600 4-bit pixels (total number of Read More

Memory cards, also popularly known as media cards and flash cards, are small, detachable devices the main purpose of which is electronic data storage. You can compare them to diskettes in this regard. Moreover, memory cards can store multiple types of data. They can store games and other applications, music; videos, pictures, documents, and a lot more. Memory cards have various applications. They are commonly used for digital photography. They are also used as data storage modules for personal digital assistants (PDA), cell phones, portable music and video players, television, Read More

PCMCIA stands for Personal Computer Memory Card International Association, an international standards body and trade association based in San Jose, California. Founded in 1989, PCMCIA aimed to create a standard for connecting peripherals to portable computers. PCMCIA developed the PC Card. PC Card or PCMCIA Card PC Cards are credit card sized removable devices designed to add extra functions to portable computers. Introduced in 1990, the cards were first known as PCMIA cards as the original standards were established by the Personal Computer Memory Card International Association. PC Cards are Read More

PXE (Preboot eXecution Environment) is a boot environment that Intel created. The PXE allows a workstation to boot up by using a network interface before it boots the operating system from the local storage devices such as the hard disk. When hard disk boot failure occurs, the computer will not boot up and a message saying “PXE-E61: Media Test Failure, Check Cable” appears. The error may also read “PXE-M0F: Exiting Intel PXE-ROM” or “Boot Failure: System Halted.” This error message repeats each time one attempts to start up the computer Read More

Overclocking is the process making a computer component run at a higher speed than that specified by the manufacturer. The components that can be overclocked include the CPU, the memory and the video cards. Although there may be many different reasons for overclocking, the most common reason is to increase hardware performance. For example the AMD Athlon 2500+ processor which normally runs at a CPU clock speed of 1.83 GHz may me made to run at a clock speed of 2.20 GHz or the GeForce 6800 cards may be converted Read More
