, that subnet mask set how much appropriate? Let's set out a formula first.2 m-Time Square =560First, we determine that 2 must be greater than 8 square, because we know that 2 of 8 is 256, that is, the number of Class C IP maximum capacity of the computer, we from 9 times a trial 2 9 is 512, less than 560, 2 10 is 1024, it seems 2 of the most suitable. The subnet mask consists of a total of 32 bits, has determined that the next 10 bits is 0, the front 22 bits is 1, the most appropriate subnet ma

I. Basic knowledge of memory management1.S3C2440 uses a maximum of two page tables: the first-level page table is used when converting in segments, and the two-level page table is used when converting pages. There are three sizes of pages: Large pages (64KB), small pages (4KB), and minimal pages (1KB). Entries are also referred to as "descriptors", which are: segment descriptors, large page descriptors, small page descriptors, minimal page descriptors--they save large pages, small pages, startin

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. Public addresses are used in the Internet and can be accessed freely in the Internet. Private addresses can on

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

In fact, I have never used a 10-bit address or a universal broadcast address. the general broadcast address should be used for communications between multiple MCU using I2C. although it is useless, it is still translated and may be used in the future: 10bit address: the number of addresses that can be extended by 10bit

on the motherboard varies with the physical memory size. However, the linear space provided for application programmers is fixed, it does not change with the physical memory, so as to ensure the portability of applications. Although the size of the physical memory can affect the performance of the application program running, and in many cases there is a minimum requirement on the size of the physical memory, these factors are only for the normal operation of an OS.The size of the linear space

Description: Each socket address structure should be implemented in network programming. So the main socket address structure after the premise network planning, address structure can be sent in two directions: from the process to the kernel and kernel processing.
