Endianness (字节序)

"Endianness is the order of the bytes comprising a digital word in computer memory.

It also describes the order of byte transmission over a digital link." Ref[5]

Xcode的文档

Byte-Order Utilities Reference

"A platform stores values either in big-endian or little-endian format. On big-endian machines,

such as PowerPC machines, values are stored with the most-significant bytes first in memory;

on little-endian machines, such as Pentium machines, values are stored with the least-significant bytes first."

3. 关于字节序

http://zh.wikipedia.org/wiki/字节序

网络字节序: TCP/IP协议要求 TCP/IP中的字段要使用 大端序(big-endian), 即Ip addres,port等需要使用大端序,

这种字节序称为网络字节序。但是TCP中数据包中采用哪种字节序完全有程序设计人员决定。
