These codes also provide digital representations for the numerals 0 through 9 that are distinguished from numbers by the fact that they are not typically used in mathematical operations. Computers also ___sounds, pictures, and videos into 1s and 0s.

A ___ is a single 1 or 0, whereas a ___ is a sequence of eight 1s and 0s. Transmission speeds are usually measured in ___, but storage space is usually measured in ___ or gigabytes.
