Circuit Breaker Pattern Basics
Fail fast to protect systems
Circuit breakers track failure rates to open and block calls to unhealthy services, serve fallbacks, then half-open to test recovery before closing, reducing cascading failures.

Detect
Track errors/timeouts and open when thresholds exceed.
Fallback
Serve cached/default responses or errors quickly while open.
Recover
Half-open with limited probes; close when healthy.

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.
