Quiz: How well do you know technical terminology?
-
What does VGA mean?
- Video graphics array
- Visual gaming adapter
- Virtual graphic animation
The correct answer is “Video Graphics Array”.
Video Graphics Array, commonly known as VGA, is a display standard introduced in the late 1980s. It was developed by IBM and has become the de facto standard for computer displays.
VGA is an analog video interface that allows computers to be connected to monitors or displays. It supports a resolution of 640×480 pixels with 16 colors or 320×200 pixels with 256 colors. Although VGA was largely replaced by digital interfaces such as HDMI and DisplayPort, but is still used for certain older systems and applications.
-
When was VGA first introduced?
- 1977
- 1987
- 1997
The correct answer is “1987”.
VGA was first introduced in 1987 as a successor to the earlier CGA (Color Graphics Adapter) and EGA (Enhanced Graphics Adapter) standards. It offered improved color depth and resolution, making it a significant advance in display technology at the time.
With its introduction, VGA quickly gained popularity and became the standard for graphics display on personal computers. It provided a reliable and widely compatible solution for connecting computers to monitors, allowing users to enjoy vivid images and graphical interfaces.
-
What is the main purpose of VGA?
- For connecting a computer to a monitor or display
- To improve game graphics
- To create virtual reality environments
The correct answer is “To connect a computer to a monitor or display.”
The main purpose of VGA is to serve as an interface between a computer and a monitor or display device. Using a VGA cable, users can easily connect their computers to external displays to view and interact with the computer's output.
The main function of VGA is to connect displays, but it also supports basic graphics playback. However, its capabilities are limited compared to modern standards such as HDMI and DisplayPort, which offer higher resolutions, faster refresh rates and support for advanced features such as audio and 3D graphics.
