Multi-threaded access to common resources often results in data confusion and unexpected results. Therefore, it is generally necessary to lock access for mutually exclusive access. The so-called "mutex access" refers to a sectionCodeOr a public

Any data is stored in the memory in binary format. For example, a short-type data 1156 is expressed in binary format as 00000100. In the Intel CPU architecture system, the storage mode is 10000100 (low-address unit) 00000100 (high-address unit),
