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
Today in doing a network audit log when required to export the report, there is a mail attachment file size, the database is bytes byte number, the request to convert to KB display, use the following function, quite to the force, special to share.
function Sizeformat ($bytesize) {$i = 0;When the $bytesize is greater than 1024 bytes, start the loop, when the loop jumps to the 4th time;while (ABS ($bytesize) >=1024) {$bytesize = $bytesize/1024;$i + +

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/1048576 * 100)/100. '
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
For example, when we refer to "data transfer speed" and "hard disk storage space", kilobytes represent 1000 (103), and when it comes to memory or CPU cache capacity, kilobytes represent 1024 (210) because they are stored here by byte-code address.
In practical applications, we often need to convert bytecode to KB, MB, GB, and so on, where we use JavaScript to convert bytecode:
The code is as f
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
A lot of people have been confused, "size" and "footprint (size on disk)" In a file or folder property usually do not match each other. The value of size represents the number of bytes in the actual size of the file, while the space-occupying value table file occupies the size of the hard disk space.This difference comes from the way the file system stores files on the drive. To reduce the number of addresses used, the file system treats a certain number of bytes as clusters. Depending on the fi
We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is

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 fe
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;

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
I learned the fread reading command and used the filesize function to compile the statistics file size function.
I learned the fread reading command and used the filesize function to compile the statistics file size function.
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
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
