Digital data is information represented by numbers (digits). All information, no matter how abstract, can be reduced to a single number. And anything that can be represented numerically can be represented in a digital computer; we simply convert the number to its binary (base 2) equivalent.
We use base 2 representations for the simple reason that it is easy to represent opposing states in a machine. If we think of punch cards, either there is a hole in a given position or there is not. If we think of DVDs, either there is pit in a given position or there is not (the absence of a pit is known as a land). If we think of magnetic mediums, either the particles are in the positive phase or the negative phase. Optical readers (such as barcode readers) use black and white stripes or boxes. Even a simple switch can be on or off.

Digital Audio Data
Which flower is a terabyte and has no root leaf or stem?
A data flower is the "terabyte" flower that has no root, leaf, or stem. It is a metaphorical representation of digital data stored in a large quantity, typically measured in terabytes, which are units of digital information.
How do data represent on an optical disc?
All digital data is represented as one's and zero's. The actual physical representation of data on an optical disc - assuming you are talking about CD's - is called pits and lands.
What is the chart that is a representation of the data in a worksheet?
What is the visual representation of worksheet data?
What is the difference between digital terrain model and digital elevation model?
DTM = Digital Terrain Model is a digital representation of the sloped contour surface of the earth. Surface features, such as man-made objects and vegetation, are not included. DEM = Digital Elevation Model is a digital representation of the sloped contour surface of the earth. Elevation data is included, along with surface features such as man-made objects and vegetation.
What is the term for a visual representation of data?
The term for a visual representation of data is a data visualization.
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
What is the conversion of letters sounds and images into electrical signals called?
The conversion of letters, sounds, and images into electrical signals is called digital encoding. This process essentially translates analog data into a digital format that can be easily transmitted and processed by electronic devices.
Is diagram the visual representation of data in Excel?
A chart is a visual representation of data in Excel.
Difference between analog representation and digital representation?
An analog representation displays information in a continuous way, for example... the presentation of a wall clock shows the time in as a continuous variable, taking on any value within its constituent resolution. digital representation, also called discrete representation, displays information in terms of discrete, symbolic values, normally in terms of codes. In keeping with the same example, a digital representation would be a digital clock, whose representation of time is in terms of discrete variables (numbers)
What did you mean by data representation explain it briefly?
Data is information that is interpreted by a collection (Representation) of explanatory words or symbols. A simple explanation is a 60mph sign at the side of the road. The figure 60 is the data while the sign embossed with 60 is the representation informing you of that which you need to know. Traffic lights are a representation that tells you by the data of different colours what you you need to know. @ is a representation of the data "at"
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
