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
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,MB,GB and Kib,mib,gib are these a
1m equals how many kb
Brain storage Conversion is 1024 to 1 units, that is to say 1m=1024k, 1024m=1g,1024g=1kg, but computer hardware is calculated in 1000 units, that is, the capacity of storage devices such as hard disk (such as 80G hard disk) =8000m, There is a storage error between the hardware and the software.
Normally, the M unit reads "Mega" sign bit MB
We know whether the network file or broadband bandwidth or mobile Internet traffic, its units are m (trillion), a lot of friends mobile phone general selection of 5 yuan packet 30M flow, the general Internet chat QQ, browsing some mobile Web pages are enough. So there are a lot of rookie friends often ask small 1M equals how many KB or 1M how big?
The so-called KB
Calculates the size of the folder, including subfolders, formatting the output folder size, number of files, and the number of subfolders.
The code is as follows
Copy Code
?Code can also be used to statistic the number of directoriesFormat output Directory size unit: BYTES,KB,MB,GBfunction Getdirectorysize ($path){$totalsize = 0;$totalcount = 0;$dircount = 0;if ($handle = Opend
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 of the "B" removed, so you ask the 1GB is 1024

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

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
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 (
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
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 Bit1 KB = 1,024 Bytes1 MB = 1,024 KB = 1,048,576 Bytes1 GB = 1,024 MB

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
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;Start:Copy codeThe Code is as follows:$ Len = filesize ("1. rmvb ");$ I = 4;While ($ I ){If ($ out = $ len/pow (1024, $ I)> 1.0 | $ I = 1 ){Switch ($ I ){Case 4: {printf ("%. 2f TB", $

I recently read the Hadoop authoritative guide book, which has been designed by many organizations,
However, my previous books seem to only teach GB,
The current textbooks may be terabytes or petabytes of data, but I'm not sure. However, in the near future, there may be larger units that can be used,
These days I 've been playing a b
I learned the fread reading command and used the filesize function. when I knew that this function was useful, I used it to compile the statistics file size function and used the filesize () function command to collect statistics on the file size, requirements: 1, with one output in 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 retaine
