Easy explanation of the differences between analog and digital and digitalization -"Digital Day" -IT is closer.Soft Bank News

On September 1, 2021, the Digital Agency for the purpose of digitalization throughout society was established, and the Digital Day was founded on October 10 and 11, 2021.That said, what kind of things are "digitized" in our lives?

Introducing the differences between analog and digital and digitalization so that you can feel the digital a little closer.

It is said that this day was a combination of "1 (Ichi)" and "0 (zero)", which expressed digital on the annual digital anniversary founded by the Digital Agency, which was established in 2021.It is a day to set up opportunities to regularly look back, experience, and review, and think about what to do to realize "no one left, digitize human -friendly".Softbank is also participating as a supporting company.

Can you explain?Explain the difference between digital and analog

When you hear analog, do you imagine "old -fashioned things" such as notes and black telephone, and on the other hand, "new things" such as machinery, data, and computer?

In fact, analog is a state of "continuous" and "fluid".Analog always handles moving information as it is, while digital cuts out information "step by step" and handles it separated.

The major difference between analog and digital is whether the data is represented in a continuously flowing state, or whether it is gradually separated.

Digital is clearly separated by a certain number, and represents information with the middle part omitted, such as "or not" or "Maru or Batsu".On the other hand, analog can always express fluctuating information as it is, so the original information can be expressed in a state close to the original form.

Of course, there is also the goodness of analog, but the need for digitalization has been increased by increasing communication data and information volume due to the appearance of the Internet and the elimination of radio waves (frequency) due to the spread of mobile phones.In addition, by digitizing music, videos, books, etc., the amount of information became compact, it became easier to interact on the network, and it became available at any time.

The digital world has only "0" and "1".All information is expressed in this combination.The expression of these numbers is called "binary method", meaning "two sets in two" and "two sets of two".For example, as the electrical signal is OFF = 0, or ON = 1, the electrical signal is suitable for representing the two conditions of "whether or not reach" or "not reach", so it is calculated automatically according to the procedure.Is used for calculation of the machine to perform.

In the case of representing the number 1 to 5, 0 = 0, 1 = 1, 2 = 10, 3, 4 = 4 = 100, 5 = 5 = 5 = 5 = 4, to express the digital in a combination of "0" and "1".101 ...
