1. Definitions of Big-Endian and Little-Endian are as follows: 1) Little-Endian is the low address of Low-byte emission in the memory, and the high-byte emission in the high address of the memory. 2) Big-Endian refers to the low address of high bytes discharged in the memory, and the low byte is discharged in the high address of the memory. For example, the number 0x12 34 56 78 in the memory is expressed as: 1) Large-end mode: low address ---------------> high address 0x12 | 0x34 | 0x56 | 0x782) Small End mode: low address ----------------> high address 0x78 | 0x56 | 0x34 | 0x12 visible. The large-end mode is similar to the string storage mode. 2.
