80×25

80x25 is a video mode for computer displays, particularly those using the VGA (Video Graphics Array) standard. It refers to the resolution of 800 pixels horizontally by 256 pixels vertically. This mode was commonly used in the 1980s and 1990s on IBM PC-compatible computers and other systems that supported VGA graphics. The 80x25 mode is characterized by its low resolution, which was a limitation of the hardware at the time. Despite its simplicity, it was widely adopted for text-based applications, such as word processing and programming, due to its ability to display a large number of characters on the screen. The mode was eventually superseded by higher resolution standards as computer technology advanced.
