The word agent is built around one central idea: something that acts.
It comes ultimately from Latin agere, meaning “to drive, lead, conduct, do, act, or set in motion.” The Latin present participle agens, meaning “doing” or “acting,” gave rise to the English word agent. Related English words include act, action, agenda, agency, and even agile. (Merriam-Webster)

These concepts are fundamental to modern data center networking, especially in cloud providers, AI clusters, Kubernetes environments, and large-scale enterprise infrastructure.
The terminology can seem confusing at first because it mixes network topology (Leaf-Spine) with traffic patterns (East-West and North-South).

Modern computer networks form the foundation of today's digital world. Every email sent, website visited, video streamed, or file transferred relies on a network infrastructure that connects devices and enables communication. One of the most fundamental concepts in networking is network topology.

The static initialization order fiasco is a C++ problem where one object with static storage duration depends on another static object whose initialization order is not guaranteed.
It usually happens with global objects, namespace-scope objects, static data members, and sometimes function-local statics during destruction.

This is a surprisingly subtle question because "method" and "member function" are often used interchangeably in practice, but there are differences depending on whether you're discussing object-oriented theory or C++ specifically.

Copy elision is a C++ optimization/semantic rule where the compiler avoids creating a temporary object and therefore avoids calling a copy or move constructor.
In modern C++, especially since C++17, copy elision is not merely an optimization in some cases. Some object constructions are defined so that no temporary object exists at all.
