WebSince the binary system uses only two digits or bits and represents numbers using varying patterns of 1s and 0s, it is known as a base-2 system. Here, 1 refers to "on" or "true," while 0 refers to "off" or "false." In contrast, the decimal numbering system is a base-10 system, where each possible place in a number can be one of 10 digits (0-9).

"In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array or bitmap index. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each one may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the array of pixels w… " - How are bitmaps represented in binary
