vertical line in lowercase letters means "￠" (currency),In the international SI prefix, c denotes centi, i.e. 1% (10-2)Circle in the periphery of the lowercase letter: "All rights reserved."In algebra, constants are often expressedIn geometry, means intercept (intercept)On a file or e-mail, cc means "copy cc"In weights and measures, CC is the abbreviation for "cubic centimeter" (cubiccentimetre)OtherIn the network language, C is often used instead of "see", such as "IC" i.e. "I see", "cu" i.e.

correct order.(reordering of the unordered data before being handed to the application tier)6. Since the IP datagram repeats, the receiving end of the TCP must discard duplicate data.(can discard duplicate data for duplicate data)7, TCP can also provide flow control. Each side of the TCP connection has a fixed size buffer space. The receiving end of TCP allows only the other end to send data that is acceptable to the receiving buffer. This will prevent a faster host from causing a buffer overfl

two bytes that CRC16 occupies are not included in the calculation. This one is generally not to be placed. (Note: This CRC32 is not the same as what we are going to say later in the end of the gzip file CRC32 the same CRC32 ... But all are calculated with 32-bit cyclic redundancy check code algorithm, but the object is different. The CRC32 object here is the GZIP header, which is calculated to take only two low-effective bytes, which make up the CRC16; and what we're going to say is that the CR

encoding letters and symbols is called character code (Character). The common character encodings used in computers include ASCII code (US standard Information Interchange Code) and EBCDIC Code (extended BCD interchange Code). In ASCII encoding, an English letter character store requires 1 bytes. In GB 2312 encoding or GBK encoding, a kanji character store requires 2 bytes. In UTF-8 encoding, an English letter character store requires 1 bytes, and a

] are sorted Based on the ascll code point, rather than the natural or incompatible ascll character set (such as EBCDIC. This also applies to the character range (LC_COLLATE) of the tr command ). Conditional ing of (LC_COLLATE) "I" or "I" based on ascll code points is reasonable (LC_CTYPE ). Date is printed in the traditional Unix format (LC_TIME ). If there are something you cannot assume, or the locale of C will have a worse effect than the existing

. common character data types include VARCHAR2. Character-related bytes are encoded in the schema, often called character set and code page. For example, 7-bit ASCII, EBCDIC, and Unicode UTF-8 The length semantics of character data types can be divided into two types: byte and character. Byte semantics: it refers to the string as a string of bytes (default). It refers to the string as a string of characters. Technically, a character is a code point

situation in the ASC11 system:A.A is 65, which is the ASCII code of character A.B.A is 97, which is the ASCII code of character A.C.5 is 53, which is the ASCII code of character 5.D. "" Is 32, which is the ASCII code of the space character.E. "! "33, which is the ASCII code of the exclamation point.This notation is better than numerical coding, he is clearer, and does not need to know the encoding method, if the system uses the EBCDIC, then A's encod

The data types include character, numberic, date, lob, and raw, these are the most basic data types. Of course, you can also customize data types in oracle! Character data types provided in oracle: Char ( ): A fixed-length string with a maximum length of 2000 bytes. if the length is not specified, the default length is 1 byte. Varchar2 ( ): A variable-l
