----------------------------
To add to the earlier point made by a individual of, shall we say, few words, I have composed my own answer.
Bitmap images are a collection of bits that form an image. The image consists of a matrix of individual dots (or pixels) that all have their own color (described using bits, the smallest possible units of information for a computer).
Bitmaps images are mainly used in photos due to their small file sizes, due to the fact that it only uses 0 and 1 to store their information. However, when magnified the pixels remain the same proportion and do not create more bits to compensate, resulting in you just getting a load of coloured cube with no particular correlation.
Basically if you want a picture that you're not going to magnify or change about much, a bitmap is right for you.
The BMP file format is a simple format used to store images like bitmaps. It is widely supported by the operating systems. It supports some simple lossless compression, can be either palette or up to RGB32 based, supports transparency, only 2D images. Due to the large image file and the availability of better formats like PNG, TIFF its use remains mostly restricted to the OS scope or as a temporary format when exchanging images.
Your question probably need answer: continuous tone images. Continuous tone images are ususally photographs captured with camera and are always bitmap or raster images. Bitmap or raster images means that image consist of pixels. Every bitmap image have fixed number of pixels. Every pixel have its own position and color in image.
You can not enlarge bitmap images without losing quality and bitmap images are larger in size then vector.
Vector and bitmap are both image files. Bitmapped images are images that are stored on a pixel by pixel basis and because of this, when you enlarge the image it can appear blocky. A vector image is constructed from dots, lines, shapes, etc. Each part has a particular position within the image with it's own dimensions. Because vector images are constructed using images, they can be enlarged without loss of image quality. Vector images do not get the blocky appearance of an enlarged bitmap image.
You can make a bitmap in paint. When you save your image just choose .bmp as the file extension.
BITMAP or GIF images
Yes, it can be used to edit many types of image files, including bitmap images.

Yes, bitmap means pixel based.
Photoshop is a raster image editor. Raster and Bitmap are two words for the same thing, so Photoshop is raster or Bitmap image editor, somewhere you will see raster, somewhere bitmap as explanation but it is basically same thing. Photoshop is primarily designed to work with bitmap images which are raster images in other words.
The image on the sensor isn't any image format, when this analogue data is put through the A/D converter and saved they are saved in a bitmap container (Jpeg and Raw (NEF, CR2, PEF Etc.) are all bitmap formats) all images are either a bitmap or a vector graphic, out of the camera they are bitmap, but the data in the file can be opened as a Vector Graphic in some programs.
