This interaction does not affect performance as much as it does portability. The binary number system is the starting point for representing information. All items in a computer's memory - numbers, characters, instructions, etc. These two values designate one of two possible states for the underlying physical memory. It does not matter to us which state corresponds to 1 and which corresponds to 0, or even what medium is used.
Systems usually deal with fixed-length strings of binary digits.
The smallest unit of memory is a single bit , which holds a single binary digit. A word is 32 bits long in most workstations and personal computers, and 64 bits in supercomputers. A double word is twice as long as a single word, and operations that use double words are said to be double precision operations. Since numbers are usually stored one per word, the number is padded with leading 0's first. For example, the number 52 is represented in a 16-bit word by the pattern 0000000000110100.
