Video RAM
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 as display content. Once the Video RAM receives data from the DRAM, it begins to convert the digital files into analog signals that the computer’s monitor can interpret. In most computer systems, Video RAM devices are dual ported, allowing them to convert display content from digital signals into analog signals while they are interpreting new data from the DRAM as display content. This method allows Video RAM devices to process data much faster and continuously display content on the monitor without waiting for new content to be processed.
Applications
Video RAM has many different applications and can be found on any electronic display device that is connected to a processing unit. While Video RAM can store content from the DRAM that the computer’s processor identifies as display content, its primary objective is to convert digital files into analog signals that can be displayed on the computer’s monitor.
Advantages
Video RAM is advantageous because it allows computers to communicate with display devices such as monitors and projectors. Video RAM is also responsible for storing display content, which decreases the DRAM’s workload, allowing the computer’s processor to analyze data much faster and concentrate on other functions such as retrieving raw data for the user. Dual ported Video RAM is advantageous because it is able to convert digital files into analog signals for the monitor while simultaneously collecting new data from the DRAM.

- DRAM (Dynamic Random Access Memory)
DRAM is Dynamic Random Access Memory. DRAM is the most common form of RAM. When someone says that a computer has "one gigabyte of RAM", what they really mean is that the computer has one gigabyte of DRAM. DRAM is called dynamic because it must constantly be refreshed or it will lose the data which [...]...
- Digital Audio-Video Cables
For audio and video lovers the good news is that there are many types of digital audio and video (A/V) cables to choose from. Usually these cables are made from either copper wire that is shielded and housed in strong casing or fiber optic usually made from clear plastic which uses pulses of light to [...]...
- Video Card
Video Cards, also known as display cards, graphics cards, graphics controllers, or graphics accelerator cards, convert binary data (bytes) into display images. The Video Card is part of the usual complement of computer hardware. The Video Card is external to the motherboard; that is, it is a separate hardware that is attached to the motherboard [...]...
- Video Scaler
A video scaler converts an existing video signal or stream from one resolution to another. It is normally used to upscale or convert a signal from a standard definition to a higher definition broadcast. Video scalers are commonly found in televisions, computer monitors, video editing equipment, audio/visual periphery devices, and broadcasting equipment. A video scaler [...]...
- Video Multiplexer
Video applications often require you to manage several different signal sources. A video multiplexer is a device that helps you put recordings of signals from multiple security cameras on one cassette. It handles several video signals simultaneously. Video multiplexers can split a monitor into various display areas and vice versa, i.e., combine output signals from [...]...
