Storage Capacity Unit: Bit, Byte, KB, MB, GB, TB, PB, EB, ZB, YB, zbyb
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 ca
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", $
You can share resources with your friends in just a few steps!
1. Select a file you want to upload.
2. Enter your email address and Click Upload.
3. Get and extract the code and copy it to your friends.

This is a PHP program to get the size of the file and the file according to the size of the file display GB,MB,KB code code is very smart code, the code is as follows:
function Sizecount ($filesize) {
if ($filesize >= 1073741824) {
$filesize = Round ($filesize/1073741824 * 100)/100. ' GB ';
} elseif ($filesize >= 1048576) {
$filesize = Round ($filesize/1048
In a file-processing system, it is easy to get the size out of some system's own method, the problem is that the size is often just a byte B.If you want to convert this byte number to a KB, MB, GB final rendering to the user, it involves the arithmetic operation of dividing and taking the remainder.Here's how:public static String getprintsize (long size) {///If the number of bytes is less than 1024, it is d
In the computer newspaper, I saw that ABN Amro's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual 50%~70% growth of storage,
So I want to see how big the PB is, and calculate the 27PB size of the hard disk about 400,000 80.
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 one floppy disk)
1 GB = 1,024
Today, I received an email from the Hotmail Member Service. It is said that there will be another change in Microsoft products.
In addition to increasing the size of the Hotmail inbox from 250 MB to 1 GB, Microsoft also launched the live series Windows Live Mail.
Windows Live Mail has the following features:

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
Bit-----bit, bit, both of which can be said. It is the smallest unit of storage data in the computer.For example: 1111 1111 or 0000 0000 Each 1 or each 0 is a bit.byte--byte (denoted by B), which is the basic unit of computer storage capacity1 byte = 8 bit = "A" or "B"//is a letter of 26 letters anyway.2 byte = 1 Kanji =2 * 8=16 bit (this sentence can also be written in 2b=1 kanji =16 bit)Kb1 KB = 1024x768 byte (or write 1 KB = 1024x768 B)MB1 MB = 102
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

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
Using the FileSize () function command to achieve file size statistics, requires: 1, in GB, MB, KB, b in one output; 2. The order of magnitude must be greater than 1 and less than 1024, and two decimal places are reserved;
Commenced construction:

$len = FileSize ("1.RMVB");
$i = 4;

Php obtains the file size and converts the file size to gb, mb, and kb. this code uses the php program to obtain the file size and displays the file size as gb, mb, the code of kb code is very intelligent. the code is as follows:
Function sizecount ($ filesize ){
If ($ filesize> = 1073741824 ){
$ Filesize = round
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
Use the FileSize () function command to implement statistics for file size, requiring: 1, one output in GB, MB, KB, B, 2. The order of magnitude must be greater than 1 less than 1024 and retain two decimal places;
Commencement of construction:
Copy Code code as follows:
$len = FileSize ("1.RMVB");
$i = 4;
while ($i) {
