3.  Digital describes electronic technology that generates, stores, and processes
data in terms of two states: positive and non-positive. Positive is expressed or
represented by the number 1 and non-positive by the number 0. Thus, data
transmitted or stored with digital technology is expressed as a string of 0's and
1's. Each of these state digits is referred to as a bit (and a string of bits that a
computer can address individually as a group is a byte).
 Prior to digital technology, electronic transmission was limited to analog
technology, which conveys data as electronic signals of varying frequency or
amplitude that are added to carrier waves of a given frequency. Broadcast and
phone transmission has conventionally used analog technology.
 Digital technology is primarily used with new physical communications media,
such as satellite and fiber optic transmission. A modem is used to convert the
digital information in your computer to analog signals for your phone line and
to convert analog phone signals to digital information for your computer.

4.  Digital information (data)is stored using a sequence of ones and zeros.
Computers are digital machines because they can only read information
as on or off -- 1 or 0(5volts or 0volts). This method of computation, also
known as the binary system, may seem rather simplistic, but can be used
to represent incredible amounts of data. CDs and DVDs can be used to
store and play back high-quality sound and video even though they
consist entirely of ones and zeros.
 Unlike computers, humans perceive information in analog. We capture
auditory and visual signals as a continuous stream. Digital devices, on the
other hand, estimate this information using ones and zeros. The rate of
this estimation, called the "sampling rate," combined with how much
information is included in each sample (the bit depth), determines how
accurate the digital estimation is.

5.  A typical CD audio track is sampled at 44.1 KHz (44,100 samples per
second) with a bit depth of 16 bits. This provides a high-quality estimation
of an analog audio signal that sounds realistic the human ear. However, a
higher-quality audio format, such as a DVD-Audio disc, may be sampled
at 96 KHz and have a bit depth of 24 bits. The same song played on both
discs will sound more smooth and dynamic on the DVD-Audio disc. This is
due to the greater number of samples (96 vs. 44.1) and the depth(which is the
greater number parts each sample is broken into. More parts means a greater approximation of the actual
signal)
 Digital information only estimates analog data(sampling), an analog signal is
actually more accurate than a digital signal. However, computers work
with digital information, so storing data digitally makes more sense.
Unlike analog data, digital information can also be copied, edited, and
moved without losing any quality. Because of the benefits digital
information offers, it has become the most common way of storing and
reading data

6. Digital data represents analog data by close approximation.
“Sampling is the process by which linear signal is broken up
into pieces. By obtaining a digital value of the small pieces of
the signal (sampled data) and equating a value. This digital
number is identified by it occurrence in time(sample rate).
Deconstructing a signal by assigning a specific value and
tagging that value for when it occurred in time, the
reconstruction of the original signal can be produced by taking
all of the different values and when they occurred in the
sequence of time with respect to start of a signal and the end
of a signal, and sending them to device which will produce a
analog signal equaling to the digital value and by sending the
digital data at the speed the data was collected (sample rate),
the original analog signal can be closely approximated to it
original form.

7. The more the data is sampled, the more accurate the
reproduction of the original signal will be. This is the
fundamental method used to represent the analog world (the
real world) digitally (the virtual world).The speed at which each
sample is take will be the determination of how close to the
original signal the digital representation will be. The greater
number of samples, means a greater accuracy of the signal.
With out this process, nothing of the real world could be
capture and stored in the digital world. Computers would be
relegated to only performing numerical calculations and
producing resulting numerical displayable results. Modern
practical uses for computers would be impossible without the
ability to convert analog to digital and digital to analog.

8. But it is the digital side that makes capturing of the analog
world practical and feasible. With the inherent abilities of
digital storage of data. Data which can represent many things,
having the ability to represent what that data refers is the most
compelling reasons for the digital paradigm as it relates to
computers.
With the exponential efforts and resulting successful use of
digital philosophy as a foundation for computer technology,
large amounts of data representing any number of degree of
accuracy can be employed to represent phenomenon in the
real world.
It is this representation that provides for the sound out of your
iPod, the clarity of the video necessary to view your “X” inch
size screen on your smart device, the turn by turn of your GPS,
and the crystal clear crisp sound of the voice at the other end
of your mobile phone call.

9.  Information is extracted via technological means from resources and new connections are
created between resources. A mobile phone extracts specific data (you sometimes willingly
and unwillingly provide) as well as connecting you to others. Big data does much the same
with structured and unstructured information. Sensors generate information about their
environment, connecting with other sensors and the broader internet.
 Digital (as a word) is used in many forms. As verb, it describes a process of raising
information intensity and connectedness via technology. Digitization is important as
making things digital changes the performance, value and cost of resources. Digitization
turns paper-based books into eBooks by changing their nature and performance.
 Digitization turns atoms into bits. As an enabler, companies are able to participate in the
digital economy. Having an online presence, providing a sales force with tablets, installing
cloud based software digitizes aspects of your business, but some moves are easy to copy,
motivate commoditization and lack the large scale impact to drive business revenue. If all
you do is digitize, digital technology becomes just another means of IT based cost
reduction rather than a transformative force – a digital business.

10.  Digital is an adjective describing an increasing information intensity and
connectedness of physical resources. Resources like facilities, processes, people,
teams become digital through the application of technologies that extract
information and connect resource and its information to other resources.
 Thinking of digital as a set of technologies (analytics, big data, mobile, cloud, social
etc.) limits digital potential to the instrument rather than the application. A
smartphone has information intensity and connectedness, but it requires applications
to transform value and disrupt industries. The term application should be considered
broad going well beyond ‘apps’ to the ecosystems we are able to build based on
making things digital
 The application of information and technology to raise human performance, is often
attributed to going “Digital”. It is this understanding that defines a “Strategy”!

11.  Society is becoming aware of the challenges to capture the full value of revolutionary
breakthroughs in digital technology. Many have used digital technology to observe the
cost of things and become more efficient, which is akin to “looking digital,” an important
but surface-level change. Some, however, are taking things further and transforming data
into new benefits and new sources of value in their lives. This more pervasive change is
what we mean by “being digital.”
 To move from looking digital to being digital, individuals must engage in a deep shift in
the way they care out their lives. From a business perspective, that shift requires as much
attention to culture and organization as it does to the technology itself.
 This some paradigm shift will effective everyone differently. The abilitity to surrender what
might be perceived as control over their lives, individuals will seek to enhance their life
experience through means which in turn may make their lives better. But what and how
will our lives evolve in this analog world, if we are governed by a “Digital Philosophy”
