bytes in megabyte

Reference: http://blog.csdn.net/vast_sea/article/details/8076934On this basic question, it is clear from a long time ago that the C standard does not specify the number of bytes that the basic type should be, and this is also related to the machine, OS, compiler, such as the 32bits operating system, VC + + compiler under the int type is accounted for 4 bytes , while the TUBORC is 2 bytes.Therefore, the widt

Bit:: The data information processed by the computer is expressed in binary number encoding, and the second binary number "0" and "1" are the smallest units of information, called "bit" or bit (bit). Byte (byte): In a computer, a "byte" (byte) is made up of several bits. The number of bits made up of bytes depends on the structure of the computer itself. Typically, a microcomputer's CPU uses 8 bits to make up a byte, which represents the code for a c

What is the number of bytes in the Java base data type? (32-bit system)BYTE 1 byte short 2 byte int 4 byte long 8 byte char 2 byte (C The language is 1 bytes) can store a Chinese character float 4 byte double 8 byte Boolean false/true (theoretically occupies 1bit,1/8 bytes, actual processing by 1byte processing)Java is encoded using Unicode. Each byte occupies 8

Arguably the most significant new feature of Python 3 is a much cleaner separation between text and binary data. Text is all Unicode and is represented by the str type, and binary data are represented by thebytes ty Pe. What makes the separation particularly clean was that str and bytes can ' t being mixed in Python 3 in any imp Licit. You can ' t concatenate them, look for one inside another, and generally pass one-to-a function that expects the othe

This article is tested under Python 3, and Python 2.x is slightly different. 1. Str/bytes >> s = ' 123 ' >> type (s) str >> s = B ' 123 ' bytes 2. type conversion between STR and bytes The conversion between Python str and bytes The type conversion between STR and bytes

From: http://hi.baidu.com/zhuhailangke/blog/item/5b7b0c1392fd7b47f919b86f.html Today, when you create a database in the query analyzer, a warning is displayed: The Table XXX has been created, but its maximum size (8926) exceeds the maximum number of bytes (8060) in each row ). If the length of the result row exceeds 8060 bytes, insert or update of the row in this table will fail. The size of each row in

Unicode only has one character set. The three characters in Chinese, Japanese, and Korean occupy part of Unicode 0 x to 0x9 fff Unicode is currently widely used in UCS-2, it uses two bytes to encode a character, for example, the Chinese character "jing" is encoded as 0x7ecf. Note that the character encoding is generally expressed in hexadecimal notation. to distinguish it from decimal notation, hexadecimal notation starts with 0x, and 0x7ecf is conver
