What Is an Arithmetic Unit?

Counting units are digital units of measurement. We usually use decimal notation. The so-called "decimal" is the relationship between each adjacent two counting units: one large unit equals ten small units, which means that the advance rate between them is "ten". The counting unit should contain two large parts, the integer part and the decimal part, and they are arranged in the following order: Beijing, Gigabit, 100M, 10M, trillion, 100 billion, 10 billion, billion, billion, 10 million, million, ten Ten thousand, ten thousand, thousand, hundred, ten, one (one), one tenth, one hundredth, one thousandth, ... There is no maximum counting unit for the integer part, and there is no minimum counting unit for the decimal part. When writing a number, if there is a decimal part, use a decimal point (.) To separate the integer from the decimal.

Mega and billion size

In the twelfth lesson "What is a trillion" in the Esperanto textbook published by China Press, it is clear that one trillion is milion-oble miliono = biliono (one million million, or 10 to the power of 12). To count this trillion, if you count 200 per minute, 12,000 per hour, 288000 per day, 10,1250,000 (105.12 million) per year, and one trillion, it will take more than 9,500 years. How many generations will it take to count! This trillion is a trillion. It is more than 769 times China's 1.3 billion population. However, we often encounter "megas" in our daily work. For example, there are "Megahertz" in table frequency, "Megohm" in table resistance, "Megapa" in pressure, and so on. However, the "mega" called by modern technology is by no means "trillion", but "million", that is, million, (that is, the sixth power of 10). It is one millionth of a trillion. In other words, if the two "megabytes" differ by one million times, if you count them as described above, the latter one can be counted in about three and a half days!

The first is to go to France, which is a self-driving system: trillions are billions, billions are trillions, and trillions are Beijing. This system was also used by Archimedes in Greece; 10 ^ 4 = 10,000, 10 ^ 8 = 100 million, 10 ^ 16 = trillion, and 10 ^ 32 = Beijing.

The second is Sino-French, which is the Wanjin system, all of which are progressive: Wan trillion trillion Gyeonggi is being loaded (trillion trillion trillion trillion trillion trillion Gyeonggi); 10 ^ 4 = Million, 10 ^ 8 = billion, 10 ^ 12 = trillion, 10 ^ 16 = Beijing.

The third method is the decimal system, which is a decimal system.

Unit of time

This is the one we are most familiar with,

The unit of measurement for computing the amount of storage in the device is (B byte), kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), terabytes (TB, terabyte), and PB (Petabyte ), EB (Exabyte), ZB (Zetabyte), YB (Yottabyte), NB (Nonabyte), DB (Doggabyte) and so on.

The number in brackets is the exponent of 2 (i.e. how many powers)

1B (byte); equivalent to an English letter, your name is equivalent to 6Bytes (6B).

1KB (Kilobyte kilobytes) = 1024B = 210B; equivalent to the content of a short story.

1MB (Megabyte) = 1024KB = 220B = 210KB; equivalent to the text content of a short story.

1GB (Gigabyte) = 1024MB = 230B = (2 to the power of 10) MB; equivalent to the score of Beethoven's fifth movement symphony.

1TB (Trillionbyte) = 1024GB = 240B = 210 GB; equivalent to the amount of X-ray picture information in a large hospital.

1PB (Petabyte) = 1024TB = 250B = 210 TB; it is equivalent to 51% of the content of the book collection in the National Academic Research Library.

1EB (Exabyte) = 1024PB = 260B = 210PB; equivalent to the words spoken by humans all over the world so far.

1ZB (Zettabyte) = 1024EB = 270B = 210EB; as the sum of the sand on the beaches around the world.

1YB (YottaByte) = 1024ZB = 280B = 210ZB; like the sum of water molecules in the Yongding River

1BB (Brontobyte) = 1024YB = 290B = 210YB; as the sum of water molecules in the Amazon

1NB (NonaByte) = 1024BB = 2100B = 210BB; as the sum of water molecules in the Pacific Ocean

1DB (DoggaByte) = 1024NB = 2110B = 210NB; as the sum of all the molecules of the entire earth
