VGA
VGA (Video Graphics Array) is a display hardware standard introduced by IBM in 1987 that defines analog video signals, resolutions, and color palettes for computer monitors. It was widely used in PCs from the late 1980s through the 2000s, supporting resolutions up to 640x480 with 16 colors or 320x200 with 256 colors. While largely obsolete in modern computing, it remains relevant for legacy systems, embedded devices, and retro computing projects.
Developers should learn about VGA when working with legacy hardware, embedded systems, or retro computing, as it provides a simple, low-level interface for video output without complex drivers. It's useful for bare-metal programming, microcontroller projects (e.g., with Arduino or Raspberry Pi), or emulating classic computers, where direct hardware control is needed for educational or hobbyist purposes.
