What mean that word DIGITAL ?

Question

everyone is using that word digital but sim to me no one can explaine what it is all about it. Please explaine, I do not like using words which function I do not know.

Answer 1

Of, relating to, or resembling a digit, especially a finger.
Operated or done with the fingers: a digital switch.
Having digits.
Expressed in numerical form, especially for use by a computer.
Computer Science. Of or relating to a device that can read, write, or store information that is represented in numerical form. See Usage Note at virtual.
Using or giving a reading in digits: a digital clock.
n.

Answer 2

Amazing that you are using a computer and not knowing what digital is?

I just feel that I should give a laymen definition for the term 'Digital'

Suppose if you need 5 kg Sugar!
I can give a box with 5 Kg of sugar in it or
give you 5 boxes of sugar having 1Kg each.

You'll find the second case easier . . .
to carry the material,
to store the material and
to use the material.

Same is with data that you and I are sharing right now.
DIGITAL is a method of storing, processing and transmitting information through the use of distinct electronic/optical pulses that represent the binary digits 0 and 1.

May I ask you something?
Do you know what is ANALOG. . ?

Answer 3

A digital system is one that uses discrete numbers, especially binary numbers, or non-numeric symbols such as letters or icons, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (an analog system).

The distinction of "digital" versus "analog" can refer to method of input, data storage and transfer, the internal working of an instrument, and the kind of display. The word comes from the same source as the word digit and digitus: the Latin word for finger (counting on the fingers) as these are used for discrete counting.

The word digital is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography. Such data-carrying signals carry either one of two electronic or optical pulses, logic 1 (pulse present) or 0 (pulse absent). The term is often meant by the prefix "e-", as in e-mail and ebook, even though not all electronics systems are digital.

A beacon is perhaps the simplest non-electronic digital signal, with just two states (on and off). In particular, smoke signals are one of the oldest examples of a digital signal, where an analog "carrier" (smoke) is modulated with a blanket to generate a digital signal (puffs) that conveys information.

Answer 5

you have stuff like a cassette tape which you can see the tape ok ?
On the tape is loads of little iron particles that form the music. Don't ask how, I dunno. But that is what you call analogue stuff. The same is for anything that plays sounds or pictures using physical stuff, like tape, like records on vinyl and so on.

Or like a camera film, you take a picture and the light physically changes the film when it hits it, as the shutter opens.

Digital means that instead of using the physical stuff to play back the sounds or pictures, they use numbers and a special decoder turns the numbers into the sound.

The problem with tape or film is that if you keep reusing it, it physically gets worse over time. You use it up, wear it out til its so thin, you can't get anymore songs on that tape. Or they sound terrible, or on a video tape, the programme looks awful

But with digital, its only numbers that change so you can re-use the tape or 'film' (for digital cameras, they have memory cards) thousands of times with no loss of quality.

So digital means numbers, or NOT using physical things to keep sounds/pictures/programmes etc on.
Hope that helps!

Answer 6

"Describes any system based on discontinuous data or events. Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on. There is no simple way to represent all the values in between, such as 0.25. All data that a computer processes must be encoded digitally, as a series of zeroes and ones. "

Answer 7

Outside of computers, its most commonly used in audio eg compact disc digital audio, where it means that the music is converted/stored in a digital representation.
