port number. 6) The presentation layer is mainly used for translation. Because different applications often use different syntaxes, in order to allow applications at both ends to exchange data smoothly, before sending the data, the sender must convert the data into the format of the transmission process. After arriving at the receiver end, the presentation layer of the receiver computer converts the format back. LConvert data into computer identifiable formats (ASCII (American standard informa

Redundancy checksum and CRC checksum are widely used in various data verification applications due to simple implementation and high error checking capability. It occupies less system resources and can be implemented using software and hardware. It is a good method for data transmission error detection (CRC is not a strictly hashed algorithm, however, it serves roughly the same purpose as the hash algorithm ). 3. Other data Algorithms Other data algorithms include some common Encoding a

Temperature temp; 4.9 Use typedef Define a synonym for a type. Use an enumeration or class to define a new type. Typedef Is to define synonyms for types, rather than defining new types. C ++ Only enumeration or classes are user-defined types, which can be used to define new types. 4.10 Remember that each declaration must describe a

to it, an error code is returned. The language of the world language is very important) Now you can contact the machine, but be careful with what you said. Many machines have their own dialects, such as ASCII and EBCDIC. The more common problem is the byte order. Unless you have always transmitted text, you must pay attention to this problem. Fortunately, people have found a solution. Long ago, people argued which order was more "correct ". Now it is
