1. General Data Transmission commands.
MoV transfer word or byte. For example: mov eax, 11 meaning: eax = 11
Movsx first extends the symbol and then transmits it.
Movzx is not extended before transmission.

interface selected for different interfaces. The smaller the LACP priority value, the higher the priority. By default, the LACP priority of the interface is 32768.D) creation of the Eth-Trunk interface in static modeThe creation process of the static mode Eth-Trunk interface is as follows:① The two ends send LACPDU packets to each other.② The active devices at both ends are determined based on the system LACP priority.③ The active interfaces of the two devices are determined based on the LACP p

Just contact the assembly, a lot of details are not very clear, wrote a decimal and hexadecimal conversion between the program (a bit of a setback.) ) as a practiced hand.Post code, hope that the passing of Daniel can give some guidance.Idea: (10->16) decimal number input when single character processing, meet enter end input, finally get a decimal number. Then loop left (processing only 4 times), take the next four bits, which is equivalent to/16The last output character. (16->10) Similar proce

is typically used to store the segment address to access the data. For example, if we want to read the contents of the 10000H unit, we can do it with the following program sections:mov bx,1000h mov DS,BX mov al,[0][......] Represents a memory unit, 0 represents the offset address of a memory cellTransmission of Word8086CPU is a 16-bit structure that can transmit 16 bits of data at once, i.e. one word at a time. For example:mov bx,1000h mov DS,BX mov ax,[0] ; 1000:0 font data fed into AX mov [0
#include, increase the speed of compilation, library-side class arbitrary modification, the client does not need to recompile
Straightforward, straightforward, no need to consider heap allocation, release, memory leak issues
Disadvantages
For Impl pointers must use heap allocation, heap release, long time will produce memory fragmentation, eventually affect the program run speed, each call to a member function to go through the impl->xxx () of a forwarding

2.1 8086/8088
The IBM PC Central Processor (processing unit) is a microprocessor inter 8088,8088 is a small version of the 8086. For writing programs, the two are almost identical. The difference between the two is: Their external communication. 8086 and the outside communication is through the 16-bit input and output channel, memory access is also a 16-bit each time, 8088 and 8086 very similar, but it and the outside world must communicate through 16-bit channel.

Paramtype is a universal reference.
Paramtype is not a pointer or a reference
So we have three types of derivation that need to be analyzed. Each one will be built on the basis of the template below, and so called:Templatevoid f (paramtype param); f (expr);Scenario 1: The parameter is a pointer or reference, but not a universal referenceThis is the simplest case
