Reserved IP address AssignmentThe unification of IP addresses on the Internet is managed by an organization called the IANA (Internet Assigned Numbers Authority, internet network number distribution agency). Depending on the purpose and security level, IP addresses can also be broadly divided into two categories: public and private addresses.

The CPU needs to take two steps to convert the addresses in a virtual memory space to physical addresses: first, we need to give a logical address (in fact, it is a segment offset. This must be understood !!!), The CPU needs to use its segmented Memory Management Unit to convert a logical address into a thread address, and then use its webpage Memory Management U

Windows users may often see an error message similar to: "error: access violation at address 836556f8. Read of address 836556f8 ". As a Delphi program developer, there are more opportunities for such errors than other users (pai_^ ).
What is "access violation "? How can we avoid it during the design period?
Access violation (unauthorized access), general protection fault (general protective error), or inval
8086 why does the CPU make the segment address * 16 + offset a physical address?
This is because the 8086 address line is 20 bits, the segment register is 16 bits, and the segment register * 16 is actually four bits to the left, form a 20-bit and 8086-bit address line match.

Memory location with address change:
You can specify to store multiple values in the memory in one command:
Values:
. Int 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60
This creates a series of continuous data values stored in the memory. Each data value occupies a unit of memory (in the above example, it is a long integer, that is, 4 bytes ). When
