short B's byte order is:01 02This is the network byte sequence. The order we see is the same as the order in the memory!Assume that the two byte streams of network data obtained through packet capture are: 01 02 The byte order is different. The order in the memory is 02 01.If this represents two bytes, you do not need to consider the byte sequence. If this represents a short variable, you need to consider the byte sequence. According to the "WYSIWYG" rule in the byte sequence of the network, th

Host Byte Order format (HBO, Host Byte Order) The format of the host's byte sequence is as the name suggests. The IP address format is related to a specific host or router. For different hosts, there are different formats for storing IP addresses. For example, for Motorola 68k series hosts,

, it is a little troublesome to indicate this variable:Define the variable short X,The byte stream address is PT, And the READ memory isX = * (short *) pt );The memory order of X is certainly 01 02.According to the rules that are not "WYSIWYG", the memory order is obviously the same as that seen, so we need to change the positions of these two bytes.The change method can be defined by yourself, but it is more convenient to use existing APIs.

Write network in C/C ++ProgramThe Network order of the bytes and the host order are often encountered. You may use the htons (), ntohl (), ntohs (), and htons () functions. The conversion function between the network byte sequence and the local byte sequence: Htonl () -- "host to network long" ntohl () -- "network to host long" htons () -- "host to network short" ntohs () -- "network to host short" These functions are required because the computer data indica

In return, the number of paid users surpassed HBO and the share price rose to $450. In 2015, Netflix earned $7 billion, paying users 66 million, of which 42 million in the US, with profits of about $80 million to $100 million. We want to develop Netflix into HBO before

variable is: 0102Assuming the local host is an Intel type, it's a bit cumbersome to represent this variable:Define variable short X,The byte stream address is: PT, in order to read the memory isx=* ((short*) PT);So the memory order of X is 01 02, of course.According to the "WYSIWYG" rule, this memory sequence is clearly not the same as the one you see, so swap the two byte positions.The replacement method can be defined by itself, but it is more convenient to use an existing API.Network byte or

Optical fiber is committed to bringing unprecedented network speeds to workplaces and homes, thus revolutionizing telecommunication and connection technologies. For example, Verizon now uses their FiOS product to provide a speed of 15 megabytes/second. If this speed can be us
