Queue Backpressure Basics
Slow down safely
Implementing backpressure means bounding queues, limiting in-flight messages, signaling producers via 429s or throttling, and shedding load gracefully to keep systems stable under spikes.

Bound and Signal
Set queue limits; respond with throttling signals to producers.
Limit Concurrency
Cap consumers/in-flight; prefer pushback over piling up.
Shed Safely
Drop or defer low-priority work with metrics and alerts.

API Basics
APIs let software request data or actions from other systems through defined endpoints and responses.
Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
What it is
Blockchain
A blockchain is a distributed ledger secured by cryptography and consensus nodes.
