digital

adj.

1. 1. Relating to, or resembling a digit, especially a finger.
   2. Operated or done with the fingers: a digital switch.
   3. Having digits.
2. Expressed in discrete numerical form, especially for use by a computer or other electronic device: digital information.
3. Electronics.
4. Relating to or being a profession or activity that is performed using digital devices: a digital librarian; digital photography.
5. Using or giving a reading in digits: a digital clock.
6. Characterized by widespread use of computers: living in the digital age.

n.
A key played with the finger, as on a piano.

digitally dig'i·tal·ly adv.

Traditionally, digital means the use of numbers and the term comes from digit, or finger. Today, digital is synonymous with computer. See also Digital Equipment.

Digital Means Perfect Copies

The 0s and 1s of digital data mean more than than just on and off. They mean perfect copying. When information, music, voice and video are turned into binary digital form, they can be electronically manipulated, preserved and regenerated perfectly at high speed. The millionth copy of a computer file is exactly the same as the original. While this continually drives the software and content publishers crazy protecting their copyrights, it is nevertheless a major advantage of digital processing.

Using a limited, predetermined numbering system to measure or represent the flow of data. Digital computers use the binary digits 1 (on) and 0 (off) to represent all data.

adj

1. involving the use of the fingers. adj 2. a means of data storage in which information is converted to numeric strings. adj 3. using alphanumeric characters to display data, as opposed to analog, which uses the relative position of needles or “hands” (as with a clock) against a background scale.

In anatomy, pertaining to the toes or fingers.

From the Latin for 'finger' — hence 'digital' counting (on the fingers). 'Digital' essentially means representing states or carrying out mathematical or logical procedures in steps corresponding to the symbolic operations of a calculus.

A digital computer works in steps representing steps of logic or computing by means of a formal code. A continuously changing function or signal may be represented digitally, as in CDs. Because the symbols of logic or arithmetical calculation are discretely different from each other, digital computers require circuits having discrete states, which can be selected at great speed. Analogue computers, on the other hand, manipulate continuous physical variables, following a change or representing a function by an equivalent change or function but of a different physical form (such as a voltage or the line of a graph).

Digital computers are far more versatile than analogue ones as, in principle, they can be programmed to perform any operation that can be stated. The same mechanism can readily be reprogrammed to perform very different operations, whereas, typically, analogue computers must be virtually rebuilt for different uses. Early analogue computers were relatively fast, because they did not go through many stepped operations, but modern digital computers can carry out up to 10⁹ operations per second. A great advantage of digital communication systems is that information is not lost over great distances, or with added noise, especially when 'repeater stations' restore the signals, as for underwater cables.

It is an open question whether the brain is essentially analogue or digital. It is interesting that we are extremely weak at digital operations, such as complicated arithmetical problems, although these are easy to carry out mechanically, or electronically in pocket calculators, which far surpass human accuracy and speed. This may well suggest that the brain works analogically rather than digitally.

Emanating from or pertaining to the digit.

• d. cushion — a wedge-shaped mass of white and elastic fibers mixed with some fat and islands of cartilage overlying the frog of the horse's hoof and acting as a shock absorbing mechanism.
• d. dermatitis — a major cause of herd lameness that has spread to occur in most countries.
— Characterized by round, proliferative, painful, raised lesion on the back of the lower pastern just above the digital cleft, most commonly on hindlimb of cattle, especially heifers. Invasive spirochete (Treponema phagedenis-like spirochetes) in lesion. Responds well to antibiotic treatment but in dairy cattle, milk withholding requirements make this uneconomic and treatment and control is usually with antibacterials in footbaths. Called also Mortellaro's disease.

• d. nerve block — local anesthesia of a digit, effected by a ring block in which a transverse plane is infiltrated, a local intravenous injection, or by a local block of individual nerves. The latter is more prone to failure if the anatomy of the part is not well established.
• d. pad — see footpad.
• regional intravenous d. nerve block — local anesthesia procured by ligaturing the digit and injecting the local anesthetic. The anesthetic is left confined to the digit for the duration of the ligaturing. A preferred technique for cattle digital surgery.
• d. sheath — a common synovial sheath shared, in ruminants and horses, by the superficial and deep digital flexor tendons.
