The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet.

In geometry, an octagon () is an eight-sided polygon or 8-gon.

Octal is a numeral system for representing a numeric value as base 8. Generally, an octal digit is represented as "0" to "7" with the same value as for decimal but with each place a power of 8. For example:

Octodontidae, from Ancient Greek ὀκτώ (oktṓ), meaning "eight", and ὀδούς (odoús), meaning "tooth", is a family of rodents, restricted to southwestern South America. Fourteen species of octodontid are recognised, arranged in seven genera. The best known species is the common degu, Octodon degus.

In geometry, an octagram is an eight-angled star polygon.

The Octateuch (, from ) is a traditional name for the first eight books of the Bible, comprising the Pentateuch, plus the Book of Joshua, the Book of Judges and the Book of Ruth. These texts make up the first eight books of the Septuagint, which provided the ordering used in traditional Christian Bibles. This order is different from that of the Masoretic Text of the Jewish Bible, where Ruth is considered part of the third section of the canon, the Ketuvim, and is found after the Song of Songs, being the second of the Five Megillot.

It is a large, funnel-shaped cavern, itself divided into ten concentric circular trenches or ditches, each called a or 'ditch'). Long causeway bridges run from the outer circumference of Malebolge to its center, pictured as spokes on a wheel. At the center of Malebolge is the ninth and final circle of hell, known as Cocytus.
