What do you know about te, kb, MB, GB, TB, Pb, EB, ZB, Yb, and Nb?

Byte is a unit of measurement used by Computer Information Technology to measure storage capacity and transmission capacity. one byte equals to eight-bit binary. Currently, we usually use the smallest unit of computing storage space (in fact, there are smaller bit, 1 byte = 8 bit ).

However, for hard disks or buckets, the minimum unit we use is KB (kilobyte), which is the 10th byte of 2. The conversion from byte to byte is 1 kb = 1024 bytes.

In the future, the conversion is basically increased by the 10th power of 2.

1kib (kilobyte) = 1024b, that is, the 10th power of 2, the pronunciation of "kilobytes"
1mib (megabyte) = 1024kib, that is, the 20 th power byte of 2, the pronunciation of "MB Byte"
1 gib (gigabyte) = 1024mib, which is the 30th power byte of 2"
1tib (terabyte) = 1024gib, that is, the power byte of 2, the pronunciation of "too Byte"
1 PIB (petabyte) = 1024tib, that is, the 50th power byte of 2, the pronunciation of "Byte"
1eib (exabyte) = 1024pib, which is the 60-power byte of 2"
1zib (zettabyte) = 1024eib, that is, the 70-power byte of 2, the pronunciation of "Z Byte"
1yib (yottabyte) = 1024zib, that is, the power byte of 2, the pronunciation of "y Byte"

Legend has it that

1nib (nonabyte) = 1024yib, that is, the 90-power byte of 2
1dib (doggabyte) = 1024nib, that is, the 100 power byte of 2
1cib (corydonbyte) = 1024dib, that is, the 100 power byte of 2

Note: many materials on the Internet have reversed nib and DiB. NB is not the largest. dB is better than Nb. Haha! The bigger one is CB.

We can see that what icech said above is not the title MB/GB/TB/Pb/EB/ZB/Yb, but an I letter is added in the middle. In fact, this is an algorithm difference, the general calculation Method Memory manufacturers and operating system manufacturers are still different. The general operating system is the binary conversion described by icech above, and the storage manufacturers, especially hard drive manufacturers, use decimal to calculate, therefore, the size of the hard disk and other storage systems is different from the description. In order to distinguish binary computing from operating system computing, the abbreviations are still different.

The binary computation adds an I letter in the middle, while the decimal computation does not.

The conversion is listed in detail below:

Decimal algorithm:

• 1 kilobyte [KB] = 1000 (103) byte
• 1 megabyte [MB] = 1 000 000 (106) byte
• 1 gigabyte [GB] = 1 000 000 000 (109) byte
• 1 terabyte [TB] = 1 000 000 000 000 (1012) byte
• 1 petabyte [Pb] = 1 000 000 000 000 000 (1015) byte
• 1 exabyte [Eb] = 1 000 000 000 000 000 000 (1018) byte
• 1 zettabyte [ZB] = 1 000 000 000 000 000 000 000 (1021) byte
• 1 yottabyte [Yb] = 1 000 000 000 000 000 000 000 000 000 (1024) byte
• 1 nonabyte [Nb] = 1 000 000 000 000 000 000 000 000 000 000 (1027) byte
• 1 doggabyte [dB] = 1 000 000 000 000 000 000 000 000 000 000 000 (1030) byte
• 1 emilbyte [Eb] = 1 000 000 000 000 000 000 000 000 000 000 000 000 (1033) byte
• 1 corydonbyte [CB] = 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 (1036) byte

Binary algorithm:

• 1 kibibyte [kib] = 1024 (210) byte
• 1 mebibyte [MIB] = 1 048 576 (220) byte
• 1 gibibyte [gib] = 1 073 741 824 (230) byte
• 1 tebibyte [Tib] = 1 099 511 627 776 (240) byte
• 1 pebibyte [PIB] = 1 125 899 906 842 (624) byte
• 1 exbibyte [EIB] = 1 152 921 504 606 846 (976) byte
• 1 zebibyte [Zib] = 1 180 591 620 717 411 303 424 (270) byte
• 1 yobibyte [YIB] = 1 208 925 819 614 629 174 706 176 (280) byte
• 1 nobibyte [nib] = 1 237 940 039 285 380 274 899 124 224 (290) byte
• 1 dogbibyte [Dib] = 1 267 650 600 228 229 401 496 703 205 376 (2100) byte
• You can use the decimal algorithm.

How big is the difference!

Looking at these numbers, you don't feel anything. Now let's just look at it. Let's take Nb as an example (Why is Nb? Can it be used?

This unit is very Nb ?)

We are about to step into the TB era. Now the standard weight of 1 TB hard drive is 670 GB (almost)

1nb = 2 to the power of 60 TB = 1152921504606846976 TB = 1152921504606846976 1 TB hard drives

The total weight is about 7.72457e+08 million tons. Currently, the largest ship, nock Nevis, carries 0.56 million tons.

That is to say, the hard disk that stores 1nb data needs to be pulled back and forth at least 1 379 388 229 1.4 billion times to about times before these numbers can be stored.

According to the shipping location, it is estimated that 1000 nononoisy noisy will be reimbursed

Now I understand the concept of 1nb. Is it a well-deserved Nb? Humans have been developing for so many years before the TB storage age, and they do not know the destruction of the world.

Before, can we develop into the Nb-era... Byte, kb, MB, GB, TB, Pb, EB, ZB, Yb, Nb
