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.

Can IO Multiplexing Replace Connection Pools for Database Access?

The article explains why database connections in Java applications usually rely on connection pools instead of IO multiplexing, discusses the blocking nature of JDBC, outlines how non‑blocking drivers could be built, and examines the practical and architectural reasons that prevent IO multiplexing from becoming the default.
