1, first, K and K case is no difference (kilo), M and M is the same
2, B is a bit, that is, a bit, B is a byte, that is, Byte, 8bit =1byte, a letter a byte, a man two bytes
3, 1024B =1KB,1024KB=1MB,1024MB=1GB,1024GB=1TB
Answer 1: Why 200M Broadband in the network transmission speed also did not reach 200M. Because b in 200Mbps is lowercase, equivalent to 25MB PS
Q-2:KB,
The size of the computer stores information, the most basic unit is byte, a Chinese character consists of two bytes, letters and numbers are composed of a byte.
Units of capacity are from small to large: bytes (B), KB, MB, GB, TB. The relationship between them is.
1tb=1024gb
1gb=1024mb
1mb=1024kb
1kb=1024 bytes
Usually people use the simple name, the back o
recursively, and then calculates their size and that is the entire file directory.
Because the file size that is returned directly is in bytes, we generally have to convert to the size we usually get, and here is the function of the unit conversion:
The code is as follows
Copy Code
function Sizeformat ($size){$sizeStr = ';if ($size {return $size. "bytes";}else if ($size {$size =round ($size/1024,1);return $size. " KB ";}
What is the storage unit of a computer?
Computer storage units are generally expressed in bit, Byte, KB, MB, GB, TB, PB, EB, ZB, BB,
We often refer to the byte abbreviation as B and ask K for the KB abbreviation. What a few k, what a few B.
Two, what is their conversion relationship? 1, the smallest unit in which the computer stores information: bit bit (
The smallest base unit is byte. Not many people do not know, the following first in order to give all units
Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB
I only know the top five, and most people know that, according to the rate of 1024 calculation
40 1tb=2 byte=1099511627776 Byte of the second order
1pb=2 's 50-time Square Byte=1125899906842624byte
60 1eb=2 byte= 1152921504606846976 Byte of the second order
1. Bit is the smallest unit of data in a computer, and each bit can have a status of only 0 or 12. Byte (byte) 1Byte = 8 bit It is the basic unit of measurement for storage space, and 1byte can store an English letter or half Chinese characters. 3. The word consists of a number of bytes, the number of words is called word length, different grades of machines have different lengths. 8-bit machine: 1 words = = a Byte, Word length is 8 bit 16-bit machine: 1 words = = 2 bytes, word length is 16 bit
Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?
Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese ch
1 TB = 1024 GB 1 GB = 1024 MB 1 MB = 1024kb 1kb = 1024 byte note: byte means B, that is, byte KB is a kilobytes of MB, that is, GB is a Gigabit, that is, a gigabit. Generally, they can be viewed as a kilobytes of data, the accuracy is that 1024 is the 10th power of 2. In the unit of storage capacity, bytes are the most
BYTE (byte) is B: A byte is made up of 8-bit binary digits (1 byte = 8 bit). Byte is the most common base unit in the information store.
An English letter (case-insensitive) occupies a byte of space, a Chinese character occupies two bytes of space.Symbol: English punctuation 2 is a byte, Chinese punctuation is two bytes.
A binary numeric sequence, as a digital unit in a computer, typically a 8-bit binary number,If an ASCII code is a byte, the conversion of such units is:
1000 gigabyte (tb,kil
1bit=1 bit 2 binary information 1B (byte byte)1KB (kilobyte KB) =2 (Ten) b=1024b=2 (ten) B;1MB (Megabyte MBytes) =2 (Ten) kb=1024kb=2 B; equivalent to the content of a short story.1GB (Gigabyte gigabytes) =2 (mb=1024mb=2) B; the equivalent of a short story.1TB (Trillionbyte) =2 (gb=1024gb=2) B; equivalent to the music

What are the storage units of a computer?Computer storage units are generally used bit, Byte, KB, MB, GB, TB, PB, EB, ZB, BB to express,We often call a byte short as B, the KB abbreviation K. What a few k, what a few B.
Second, what is their conversion relationship? 1, the smallest unit
In the computer newspaper, the Dutch bank's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual growth of 50%~70% reserves,
So want to see how much PB, calculate 27pb about 400,000 80 of the hard disk size.
1Byte = 8 Bit (0,1)
1 KB = 1,024 Bytes (size of a shortcut)
1 MB = 1,024 KB = 1,048,576 Bytes (size of a floppy disk)

The size of the php statistics file, which is measured in GB, MB, KB, and B. Use the filesize () function command to calculate the file size. the value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained. use the filesize
Having stayed at school, I went over PhP and looked at the previously written functions. I suddenly wanted to write the known file size and sort the data.
For example: 1.3G, 153 MB, 458kb, 998 m, 0.99g (the difference between MB and MB is not considered here, and generally does not involve the operation of MB, so
Idle boredom comes to the end:
bit:
We often say bit, what is the bit. bit is the smallest unit of data in the legendary computer: it's 0 or 1, and the storage in the computer's memory is 01 of these two things. Well, yes, that's the way it is.
bytes:
English words: (byte), byte is the basic unit of measurement of storage space, so the problem is, since it is the measurement unit of storage space, what is the storage of it, you just have to remember these two words on OK: 1byte deposit 1 E
