Purpose

This collection keeps factual notes about how systems are built and how their boundaries behave: memory and addressing, the client-server boundary, and the protocols that connect components. The aim is a reusable reference for reasoning about systems, not a record of one specific setup.

Current Reading Path

  1. Mathematical Foundations of Memory Address Mapping
  2. The First API Boundary I Had to Understand

Planned Areas

  • Memory hierarchy and addressing
  • Networking and protocols
  • Concurrency and distributed memory
  • Operating-system interfaces

Status

Two complete bilingual notes so far. New pages should be added in English and Chinese together.
