Reference"Deep understanding of computer systems"Deep understanding of the Linux kernel"80x86 assembly Language Programming""The design and implementation of the operating system" In order to protect the program and data in memory and share hardware support, in order to provide hardware support for realizing virtual memory, modern CPU not only uses the extended memory segment management mechanism , but also provides optional memory paging management mechanism. Physical addresses (physical

Logical addresses (Logical address)Refers to the part of the offset address that is generated by the program that is related to the segment. For example, you can read the pointer variable itself ( operation) in the C language pointer programming, which is actually the logical address, which is relative to the address o

This blog post self-informed answer: Linux linear address, logical address and virtual address of the relationship?In order to prevent ambiguity, the following terms are used in English. Some of the terms are not explained, otherwise the answer will be too long.The following is an example of a code snippetUnder the Intel platform, the logical

Subnet Mask and IP address calculation network address and broadcast address conversion IP Address: 202.112.14.20.Subnet Mask: Too Many Subnet MaskWhat is the network address and broadcast address of this host?Solution:St

Logic address to linear address The memory addresses in machine language commands are logical addresses, which need to be converted to linear addresses and then converted to physical addresses by MMU (Memory Management Unit in the CPU. We will write the simplest Hello World Program and compile it with GCC. After disassembly, we will see the following command:MoV 0x80495b0, % eax The memory

one, logical address to linear addressThe memory address that appears in the machine language instruction is a logical address that needs to be converted to a linear address and then converted to a physical address by the MMU (Memory management unit in the CPU) to be accessi

A logical address is a segment-related offset generated by a program. For example, you can read the value ( operation) of the pointer variable in the C language pointer programming. In fact, this value is the logical address, which is relative to the address of the Data Segment of your current process, it is not related to an absolute physical

Address Resolution Protocol ARP: 1. Why Address Resolution Protocol is required. usually a host to the B host to send data, a host generally know the IP address of Host B, light has an IP address can send data. No, in the network interface layer, the host located inside the LAN is communicating through the MAC

Understand the runtime address and link address from the two-statement assembly, and the Assembly link address First, let's look at two lines of assembly code: 1: adr r0, _start 2: ldr r1, =_start Load the address value of a label. What is the difference between adr and ldr? Note that the ldr here is not a

A few words to master subnet mask, IP address, host number, network number, network address, broadcast address1, 191.172.16.10.33/27 in the/27 that is, the subnet mask is 255.255.255.224 that is 27 full 12. From the subnet mask 255.255.255.252 to obtain its network bit is 30 bits, so only the remaining 2-bit master, the host bit of all zeros for the network address
