I have known asynchronous IO for a long time, but it has not been used recently to solve the actual problem (in a CPU-intensive application, some data to be processed may be stored on the disk. The location of the data is known in advance, so an asynchronous IO read request is initiated in advance. Wait until you really need to use these... information I have known asynchronous

IO modelLinux system IO is divided into two phases: The kernel prepares the data and copies the data from the kernel to the user space.This diagram outlines the process of moving data from an external disk to the memory of a running program.User space, kernel spaceNow the operating system is using virtual memory, then for the 32-bit operating system, its address space (virtual storage space) is 4G (2 of 32)

Python basic-I/O model and python-io Model I. I/O model IO indicates Input/Output in the computer, that is, Input and Output. Because the program and runtime data reside in the memory, it is executed by the super-fast computing core of the CPU, which involves data exchange, usually disks and networks, and IO interfaces are required. What are the differences betwe

Note: This article is a lot of blog learning and summary, there may be an understanding error. Please take a skeptical look at the same time if there are mistakes to be pointed out. What is the difference between synchronous IO and asynchronous Io, what is blocking IO and non-blocking IO respectively? The answers given

36. IO model, 36io Model In particular, this essay is copied to egon (Lin Haifeng ). I. IO model Introduction To better understand the IO model, we need to review in advance: synchronous, asynchronous, blocking, non-blocking What are the differences between synchronous I/O and asynchronous I/O, blocking I/O, and non-blocking I/O? Different people may give differe

Synchronous (synchronous) IO and asynchronous (asynchronous) Io, what is the difference between blocking (blocking) IO and non-blocking (non-blocking) IO, respectively. The problem is that different people may give different answers, some think asynchronous IO and non-blocki

Socket. io (3) Deep Learning Preface Socket. io provides real-time event-based two-way communication. This article introduces socket. io in depth. Let's take a look at the details below. Static files By default, socket. io uses the socket. io-client package to provide socket

-blocking: When an event or task is executing, it issues a request action that, if the requested action requires a condition that is not met, immediately returns a flag informing that the condition is not satisfied and will not wait there.This is the difference between blocking and non-blocking. That is, the difference between blocking and non-blocking is that when a request is made, if the condition is not met, it waits or returns a flag message. blocking i
