megabyte vs kilobytes

PHP implements the format file data size display method, This article describes how PHP implements the format file data size display. Share to everyone for your reference. The specific analysis is as follows: Sometimes we need to show the size of a file on a Web page, or the size or number of other data. This number is often from a large span, if the unit B is a bit, if 1G is up to 1073741824 of the number, this time we need to format according to the size, such as less than 1K is displayed in

Storage capacity: Is the maximum number of data that can be stored on the storage device, typically using kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), terabytes (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure.1Byte (equivalent to an English letter, a kanji account of 2 byte)1kb=2 (b=1024b); Quite a short story.1mb=2 (kb=1024kb=2) B; Quite the text of a short

sometimes we need to show the size of a file on a Web page, or the size or number of other data. This number is often from a large span, if the unit B is likely to be bit, if 1G is up to 1073741824 of the number, this time we need to format according to size, such as less than 1K is displayed in units B, less than 1M is displayed in kilobytes, Less than 1G is displayed in megabytes, etc. ...The Format function reference is as follows:Format size Displ

The code is as follows Copy Code byte conversionsfunction conversion ($size) {$KB = 1024; 1KB (Kibibyte, kilobytes) =1024b,$MB = 1024 * $KB; 1MB (Mebibyte, megabyte, abbreviation "trillion") =1024kb,$GB = 1024 * $MB; 1GB (gigabyte, Gigabyte, also known as "gigabit") =1024MB,$TB = 1024 * $GB; 1TB (terabyte, trillion bytes, too byte) =1024GB,$PB = 1024 * $TB; 1PB (Petabyte, quadrillion Byte, P

Oracle systems use to hold temporary data. For example, when sorting is required in an operation, theOracle system temporarily stores the sorted data in the tablespace. Sort at The space occupied by the ordered data is released when the manager is finished , so it is called a temporary tablespace.CREATE TABLE Space　　　　CREATE tablespace tablespacenameDataFile'filename' [SIZE integer [K | M]] [,...][Autoextend [OFF | On]]; Explain: Tablespacename is the name of the tablespace you want to create.

want to keep after shutting down must be placed there. In summary, there are these stores around the CPU: Storage Area Unit of Measure CPU Registers bytes CPU Cache Kilobytes Ram Megabytes Disk drive Gigabytes You can see that the farther away the CPU is, the larger the storage. In theory, a large amount of persistent storage can

Computer storage unit bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit. Byte: eight binary bits are one byte (B), the most common unit. That is, 1B (byte bytes) = 8 bit computer storage units are generally represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, BB, the relationship between them is: 1 kb (kilobyte kilobytes) = 1024b, 1 MB (megabyte megabytes referred to

of binary numbers, which is generally an 8-bit binary number as a numerical unit in a computer. For example, an ascii code is a byte. The conversion of such units is:1 gib (TB, terabyte) = 1024 gib (40 to the power of 2)(1 TB = 1024 GB)1 gib (GB, gigabyte) = 1024 MB (2 to the power of 30 bytes)(1 GB = 1024 MB)1 MB (megabyte) = 1024 kilobytes (20 to the power of 2)(1 MB = 1024kb)1024 bytes (kb, kilobyte) =

Iostat command ExplanationThe iostat is used to output CPU and disk input and output, partition, Network File system NFS-related statistics. The Iostat command monitors the input/output status of system devices and generates reports to modify the system configuration for better performance based on statistical reporting.Command format:Iostat [-c] [-d] [-n] [-n] [-h] [-K |-m] [-t] [-v] [-X] [-z] [device [...] | ALL] [-p [device [,...] | all] [interval [count]]Iostat can produce three types of rep

that the eth0 outlet has 100mbit/s bandwidth, assigned to WWW, e-mail and Telnet three data traffic, which is allocated to the WWW bandwidth of 40mbit/s, the bandwidth allocated to the email is 40mbit/s, the bandwidth allocated to Telnet is 20Mbit SIt is important to note that the following abbreviations are used in the TC to indicate the appropriate bandwidth:Kbps kiiobytes per second, or "kilobytes per second;Mbps megabytes per second, or "

of the system's maximum pathname (defined in the/usr/include/sys/limits.h file).If you do not specify an input file or if you specify-(minus) The file name, the split command reads the file from the standard input.SignNote: the-B and-L flags are mutually exclusive.-a suffixlength Specifies the number of letters used to form the suffix portion of the output name file. Number of letters determines the number of possible combinations of output file names. The default is two letters.-B divides the

when multiple data files are available; FileName is the path and name of the data file; Size Specifies the file sizes, using K to specify the size of the kilobytes, and M to specify the megabyte size; The Autoextend clause is used to enable or disable automatic extension of the data file, set to on to automatically expand when the space is used, and set to off it is easy to have a table space r
