NameCheap is a foreign domain name registrar. It offers affordable domain name registration and transfer prices and is favored by many friends. If your domain name is registered in Namecheap, by default, the free DNS resolution service provided by Namecheap is used. However, your users are mainly targeting China, and the default DNS is unstable and slow, therefor

Today, when I went to try it, I was suddenly blindfolded, and many of the features needed were not found and the speed of the backstage opening was slow. But it's a lot simpler to experience and function than it was in the background. If for our frequent contact with overseas host, domain na

How do I know I'm done with IO?first, the event-driven model introductionTypically, when we write a program that server processes a model, there are several models: (1) Each time a request is received, a new process is created to process the request;(2) Each time a request is received, a new thread is cre

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Differences between registers and memory Both registers and memory can be used for reading and writing, but register operations have side effects) Reading a register may change the content in the register. For example, in some device interrupt status registers, the registers are autom

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall
