kb albums

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 MB, MB, and MB are regarded as mb. In fact, MB = 8 * MB) The function is as follows: PHP Function Sortsize ( $ Arr ){ $ Arr2 = $ Arr ; $ Arr3 = Array (); If (! Is_array ( $

);/* determine whether the memory card is inserted */If (environment. getexternalstoragestate (). equals (environment. media_mounted) {/*. The path to the SD card file is/sdcard */File Path = environment. getexternalstoragedirectory ();/* statfs View File System space usage */statfs = new statfs (path. getpath ();/* block size */long blocksize = statfs. getblocksize ();/* Total number of blocks */long totalblocks = statfs. getblockcount ();/* number of blocks in use */long availableblocks = stat

Some time ago, I published an article titled the appearance and Analysis of Large-sector hard disks"To illustrate the emergence of large-sector hard disks in, and some readers have also sent a letter to ask, here, reprinted an article by foreigners, again to explain 4 K large-sector hard disks, we hope that you will have a better understanding of the 4 K large-sector hard drive and deepen your understanding of the impact of the 4 K large-sector hard drive on the real system!

When we choose VPS, Server host, we often see the common MB, GB, Mbps, and so on some of the labeling units. Most of us will probably know MB (megabytes), which is much larger than the amount of memory we often use. But if the bandwidth is involved in Mbps, it may be a bit difficult to understand, such as we often see that there is 2Mbps bandwidth, many people will understand that 2MB, and then use the file drag test to find out how no 2MB, so will be all kinds of complaining about the business

The solution for importing phpmyadmin database to KB is as follows. Solution 1 of phpmyadmin database import of KB. open php. ini. Find the upload_max_filesize, memory_limit, and post_max_size parameters! (By default, php only allows the phpmyadmin database to be imported 2048kb. 1. open php. ini. Find the upload_max_filesize, memory_limit, and post_max_size parameters! (By default, php only allows the max

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. ' MB '; } elseif ($filesize >= 1024) { $filesize = Round ($filesize/1024

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

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 directly in B, otherwise except for 1024, the

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 follows Copy Code function Byt

Reorganize the store, recover the database file, and find that four ndf file size becomes 0 KB. The database size is approximately 80TB. There are 1223 files in the database, the database generates a NDF file every 10 days, each ndf is about 500GB, and the database contains two LDF files.Second, fault analysisSt

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 (bit) (Binary Digits): holds a binary number,

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 70 1zb=2 byte= 1180591620717411303424 Byte o
