Binary numbers are stored in computers as groups of bits.
Bits are the smallest unit of storage in a computer. The word comes from combining the two words binary and digit. In a computer, a bit can either be on or off, representing either the binary digits 1 or 0.
To make longer binary numbers, several bits are needed. For example, the binary number 101 (5 in decimal) requires 3 bits. A byte is made up of 8 bits. Sound familiar?
