Understanding I/O Models in Python Network Programming
In Linux-based network programming, I/O operations involve two distinct phases: waiting for data to become available in the kernel, and copying that data from kernel space to user space. Different I/O models vary in how these phases are handled.
Blocking I/O is the default behavior for sockets. When a process calls recvfrom(), it blocks until b ...

Understending I/O Models
In high-performance networking, the interaction between the application (A) and the system kernel (B) is defined by two primary dimensions: Synchronicity and Blocking behavior.
1. Synchronous vs. Asynchronous
Synchronous: The requesting program must actively query the status of a task. It remains responsible for checki ...
