The smallest basic unit is byte should not have 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 it, according to the rate of 1024 calculation 1tb=2 's 40-Time Square byte=1099511627776 Byte 1pb=2 's 50-time Square Byte=1125899906842624byte 1eb=2 60-Time Square byte= 1152921504606846976 Byte 1z

equals 8 bits (1byte=8bit). Eight-bit binary number minimum is 00000000, the maximum is 11111111; usually 1 bytes can be stored in an ASCII code, 2 bytes can hold a Chinese character GB code.3, the wordWhen a computer is processing data, the length of time it accesses, processes, and transmits is called word. A word is usually made up of one or more bytes (usually the integer bits of bytes). For example, the word 286 microcomputer consists of 2 bytes

After migrating a SMS interface code from Apache to NGINX+PHP-FPM, I found that I could not send a text message to see the PHP log, [25-sep-2014 20:15:21] WARNING: [Pool www] child 9617 said in stderr: "notice:php message:php Fatal error:call to undefined function mb_conv Ert_encoding () in/data/htdocs/xx.php on line 13″ found that the function mb_convert_encoding is not defined, looking like a module is not installed, Google put, to install a mbstring expansion, before a lot of expansion (alt

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 b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M of fiber, that is 1M b/s =1 M/8 b/S =0.125

In the evaluation of IP address- gt; geographic position conversion, ip2addr function is the most efficient function to directly read IP database files. compared with MySQL database, SQL queries are the most efficient. However, the IP database file QQWry. dat is GB2312 encoded. Now I need the geographic status results of UTF-8 encoding. If MySQL is used, data can be converted The article "IP address-> geographic status

PHP on several methods of dynamic conversion of GB encoding to UTF-8 evaluation.

Using the IP2ADDR function to read the IP database files directly is the most efficient, and SQL query is the most efficient one, compared with the MySQL database to store the IP data. However, the IP database file QQWry.dat is GB2312 encoded. Now I need UTF-8 coded geographic results. If you use the MySQL method, you can convert the data to the UTF-8 code when it is stored in the database. But QQWry.dat file can not be modified, only the output of the IP2ADDR function can be dynamically convert

result of the ip2addr function can only be dynamically converted. There are at least four methods for dynamic conversion of GB-> UTF-8 encoding: Extended conversion using php iconv Extended conversion using PHP mb_string Use swap table conversion, swap table stored in MySQ

commonly used in text, Chinese characters are confused with single-byte ASCII codes if they are not specifically identified. One solution to this problem is to treat a Chinese character as a two extended ASCII code, making the highest bit of two bytes representing the GB2312 Kanji 1. This high-level 1 double-byte Chinese character coding is the GB2312 character of the in-machine code, referred to as internal code.Therefore, the "learning" word of the in-machine code is:11010001 10100111The d1a7

The characters in wince are unicode encoded, and the XML used for the project also needs to be unicode characters, while the LCD in the project is a GB character, there is a conversion problem between the two after google, we found that this type of conversion can only be performed in the form of a look-up table. We made the characters corresponding to unicode an

We know that using nsurlconnection proxy method to download the Web page, to save in a nsdata, Nsmutabledata *pagedata;[Pagedata Appenddata:data];If the page encoding is utf-8 , you can convert this to a string: NSString *pagesource = [[NSString alloc] Initwithdata:pagedata encoding:nsutf8stringencoding];if the page is GBK(or gb2312), pagesource returns nil with UTF8 conversion . At this time need to use GBK encoding to do the
