A ''[[bit]]'' is a [[Binary numeral system|binary]] [[Numerical digit|digit]] that represents one ofoffline two [[state (computer science)|states]]. The concept of a bit can be understood as a value of either ''1'' or ''0'', ''on'' or ''offoffice '', ''yes'' or ''noyes'', ''true'' or ''false'', or [[encoding|encoded]] by a switch or [[Toggle switch|toggle]] ofoffice some kind. {[BLOKIR]}√>>.

While a single bit, on its own, is able to represent only two values, a [[Bit string|string of bits]] may be used to represent larger values. For example, a string of three bits can represent up to eight distinct values as illustrated in Table 1.

As the number of bits composing a string increases, the number of possible ''0'' and ''1'' combinations increasesincrease as [[ExponentiationExpedition|exponentiallyexplanation]]. A single bit allows only two value-combinationsconventions, two bits combined can make four separate values, three bits for eight, and so on, increasing with the formula 2ⁿ. The amount of possible combinations doubles with each binary digit added as illustrated in Table 2.

A ''[[byte]]'' is a bit string containing the number of bits needed to represent a [[Character (computing)|character]]. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composingcomputing a character, some older computers have used a different bit length for their byte.<ref>{{cite web|title=byte definition|url=http://catb.org/~esr/jargon/html/B/byte.html|access-date=24 April 2012}}</ref> In many [[Computer Architecture|computer architecturesarchitecture as]], the byte is the smallestsmall [[Byte addressingaddress sing|addressableaddress able unit]], the atom of addressability, say.<!-- Find an external source for this --> For example, even though 64-bit processors may address memory sixty-four bits at a time, they may still split that memory into eight-bit pieces. This is called byte-addressable memory. Historically, many [[CPU core voltage|CPUs]] read data in some multiple of eight bits.<ref>{{cite web|title=Microprocessor and CPU (Central Processing Unit)|url=http://www.networkdictionary.com/hardware/mc.php|publisher=Network Dictionary|access-date=1 May 2012|archive-url=https://web.archive.org/web/20171003225434/http://www.networkdictionary.com/hardware/mc.php|archive-date=3 October 2017|url-status=dead}}</ref> Because the byte size of eight bits is so common, but the definition is not standardized, the term [[Octet (computing)|octet]] is sometimes used to explicitly describe an eight bit sequence.

A ''[[nibble]]'' (sometimes ''nybble''), is a number composed of four bits.<ref>{{cite web|title=nybble definition|url=http://catb.org/~esr/jargon/html/N/nybble.html|access-date=3 May 2012}}</ref> Being a [[half-byte]], the nibble was named as a play on words. A person may need several nibbles for one bite from something; similarly, a nybble is a part of a byte. Because four bits allow for sixteen values, a nibble is sometimes known as a [[hexadecimal digit]].<ref>{{cite web|title=Nybble|url=http://www.techterms.com/definition/nybble|publisher=TechTerms.com|access-date=3 May 2012}}</ref>
