From the past few decades, we are moving towards the digitalization. In today’s time, everything seems to be digital from watch to radio player, cameras, cell phones, and even the books. However, what is the difference between analog and digital technology? Which is the best among both? Arya College of Engineering and IT supports and promote both form technologies.
Let us discuss both the technologies one by one for
the better understanding.
Analog
Technology
Analog technology is the measurement of the analogy of
time or length. For instances, if you measure the length of your thumb, and
mark it on the surface of a ruler. Then, that little segment of the ruler is of
the same length as that of your finger. Hence, it is known as the
representation of your finger. This example is the analogy, and it tells the
meaning of the analog technology.
Measurements
in Analog Technology
In the 20th century, when there is no takeover of
computers in science and technology, every instrument of measurement was
analog. For instances, if you have to measure the electric current. You have to
use a moving coil- meter with a pointer at the dial. During the measurement, if
the pointer is moving up the dial, then the current in the circuit is higher
and vice versa. Here, the analogy is the pointer of the dial. Other
instruments, which measure with the same phenomenon, are seismograph, weight
machine, and speedometer.
About
Analog Technology
Analog technology not only signifies the measuring
instruments but it signifies everything that is not digital. The analog
technology does not involve any electronic representation of numbers. The old-
film cameras and cassette recorders are the best examples of analog technology.
In old- film cameras, the pictures we clicked represent the analogy of the
scene we wished to record. On the other hand, in the cassette recorder, the
recording is the analogy of the sound you heard originally.
Digital
Technology
Digital technology is completely different from analog
technology. In digital technology, you do not have to represent your pictures
and sounds in the form of films and tapes. Instead, you can convert the information
in the form of numbers. Moreover, you can also store these numbers.
Measurements
in Digital Technology
In today’s time, most of the devices use digital
technology. For instances, the BP meters, thermometers, multimeters are some of
the common measuring instruments that focus on digital technology. The digital
technology is much easier than analog technology. However, the accuracy of the
measurements totally depends upon the mode of measurements.
About
the Digital Technology
The technology we are using in our daily life is
digital technology. Cell phones are the best example of digital technology. In
cell phones, the transmitters convert the sound in the number and then travel
in the form of radio waves. Therefore, digital technology is easier to store
the information. Moreover, it will consume less time. The information in
digital technology is more secure, as the conversations in cell phones are
encrypted on both ends. In digital technology, the user can edit and play the
technology easily. Anyone can alter a picture with the manipulation of the
numbers instead of the picture itself.
Analog
OR Digital
However, digital technology is the future of the
world, but the analog will somehow make its place. For example, the digital
watches are more accurate than, that of analog watches but still, the most
expensive watches are analog ones. Moreover, the atomic clocks, which are the
most accurate watch of the world, display the time digitally. In conclusion, to
this, though digital technology has many advantages, it does not mean that it
is always the best.
Both technologies, either the digital technology or the analog technology have their equal importance. At last, both the technologies should move hand-in-hand. The proper balance of both the technologies is the need of the time.
