In the colors, bit has an important role as it helps to calculate color depth by 2 to the power of the bit color. For example, an 8-bit color describes 256 colors that would be 2^8.
Bit-based computing
Instead of manipulating data interpreted as combined bits, few computer instructions (bitwise computer processor instructions) work on the level of manipulating bits. For setting or copying the bits that corresponded to a given rectangular area on the screen, bit block transfer instructions were offered by some computers when bitmapped computers were gaining popularity on the market in the 1980s.
When a bit within a group of bits like a byte or word is referred to in most computers and programming languages, so, within the byte or word, it is defined with the help of a number from 0 upwards corresponding to its position. However, on the basis of the context, 0 can refer to the most or least significant bit.
A bit is an acronym, can we write it in all uppercase?
