​KembaraXtra-Computer Terms – bitmap:
A bitmap is a data structure used in computer memory to represent information as a collection of individual bits. In graphics systems, each bit or group of bits corresponds to a pixel that forms part of an image displayed on the screen.
Bitmaps are also used in other contexts, such as disk management, where they represent whether storage blocks are free or already in use. Because each position in the bitmap corresponds to a specific element, the structure provides an efficient way to track and manage system resources.
