In some contexts, the term bitmap implies one bit per pixel, whereas pixmap is used for images with multiple bits per pixel. [3] [4] A bitmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of ...
The BMP file format, or bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows [2] and OS/2 [3] operating systems.
It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w is the number of bits in the unit of storage, such as a byte or word, and k is some nonnegative integer.
Bitmap is a type of memory organization or image file format used to store digital images. Bitmap or bit map may also refer to: Bit array, general bit-addressed data structures; Bitmap graphics, also known as raster graphics, an image represented by a generally rectangular grid of pixels (co-sitting points of colors)
A region of memory (or resource) used as both a render target and a texture map. Texture map A bitmap image/rendering resource used in texture mapping, applied to 3D models and indexed by UV mapping for 3D rendering. Texture space The coordinate space of a texture map, usually corresponding to UV coordinates in a 3D model.
The term frame buffer is thus often used interchangeably when referring to this RAM. The CPU sends image updates to the video card. The video processor on the card forms a picture of the screen image and stores it in the frame buffer as a large bitmap in RAM. The bitmap in RAM is used by the card to continually refresh the screen image. [15]

The simplest form of free-space bitmap is a bit array, i.e. a block of bits. In this example, a zero would indicate a free sector, while a one indicates a sector in use. Each sector would be of fixed size. For explanatory purposes, we will use a 4 GiB hard drive with 4096-byte sectors and
