BIT (alternative information centre)

BIT was an information service, publisher, travel guide and social centre founded, in 1968, by John "Hoppy" Hopkins. It pre-dated the internet as a free service that would try to find any information asked for and derived its name from the smallest unit of computer information.

BIT

BIT was initially a partial spin-off from Hoppy's earlier International Times information service, which was being overwhelmed by the number of enquiries it was receiving, then subsequently took on a life of its own, becoming a much wider organisation more akin to the later social centres. Emerging from the UK underground as a volunteer-run business, it evolved into a collective and open house based in Notting Hill.

Although often undefinable, one staff member tried with "We're open every day of the year from 10am to 10pm (telephone 24 hours) and we give free help and information about anything to anyone who wants it. Dirty, untidy office; friendly, sometimes exuberant atmosphere, inefficient staff, confused clientele, aggressive cat. Free information, free bogs, free bath. free duplicator and typewriter, free kittens and puppies, free clothes, free food — cheap at other times but free if you're really starving, free people to talk to, free alternative library, free day-room to freak out in or sleep in, free crashpad, lots of other free floor space depending on the season, free optimism, free ecstasy, free lots of other things plus expensive travel guides to pay for it all."

Bit

A bit, also known as a Shannon, is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0or1. The term bit is a portmanteau of binary digit.

The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/−), activation states (on/off), or any other two-valued attribute. The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. The length of a binary number may be referred to as its bit-length.

In information theory, one bit is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known.

In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two classical (i.e., non-quantum) bit values.

Bit (horse)

A bit is a type of horse tack used in equestrian activities, usually made of metal or a synthetic material, and is placed in the mouth of a horse or other equid and assists a rider in communicating with the animal. It rests on the bars of the mouth in an interdental region where there are no teeth. It is held on a horse's head by means of a bridle and has reins attached for use by a rider.

Basic types

Although there are hundreds of design variations, the basic families of bits are defined by the way in which they use or do not use leverage. They include:
