Understanding IO Models: Blocking, Non‑Blocking, Multiplexing, Signal‑Driven and Asynchronous IO

This article explains the fundamentals of input/output (IO) in operating systems, covering the basic IO concept, the role of the OS, the two‑phase IO call process, and detailed descriptions of blocking, non‑blocking, multiplexed (select, poll, epoll), signal‑driven and asynchronous IO models with example code.

Understanding Blocking, Non‑Blocking, and I/O Multiplexing Models in Unix Network Programming

This article introduces the basic concepts of I/O and explains three Unix network programming models—blocking I/O, non‑blocking I/O, and I/O multiplexing—detailing their workflows, advantages, disadvantages, and practical analogies for better comprehension.

Understanding Java Blocking I/O, NIO, and AIO: From Per‑Connection Threads to Multiplexed and Asynchronous I/O

This article explains how traditional per‑connection thread handling (blocking I/O) wastes resources, then demonstrates Java NIO multiplexing and AIO callbacks with complete code examples, showing how they reduce thread usage and eliminate blocking while processing many simultaneous socket connections.
