<p><b>New page</b></p><div>'''Bit''' is the most basic unit of information in computing and digital communications. The name is a portmanteau of '''binary digit'''. The bit represents a logical state with one of two possible values. These values are most commonly represented as either "1" or "0".<br />
<br />
==Etymology==<br />
The term '''bit''' is a portmanteau of '''binary digit'''. The concept of a binary digit can be traced back to [[Gottfried Leibniz]] who, in the 17th century, developed the binary number system. [[Claude Shannon]] first used the term "bit" in a 1948 paper, "A Mathematical Theory of Communication".<br />
<br />
==Definition==<br />
In the context of information, a '''bit''' is a binary decision or a digital state that can be on or off, true or false, positive or negative, or one of a pair of opposites. In most modern computing devices, a bit is a form of binary code and is the most basic unit of data.<br />

* [[Nibble]]: A nibble is a four-bit aggregation, or half an octet.<br />
* [[Binary code]]: Binary code represents text, computer processor instructions, or any other data using a two-symbol system.<br />
* [[Binary number]]: A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method which uses only two symbols: typically "0" and "1".<br />
