Network Fundamentals
Understand how data moves
Network fundamentals cover how packets are addressed, switched, and routed using IP, subnets, and ports, enabling applications to communicate reliably across local and wide networks.

Addressing
IP addresses and subnets define where packets should go and how they are grouped.
Transport
TCP provides reliable streams; UDP provides lightweight datagrams for latency-sensitive uses.
Routing and Switching
Routers direct between networks; switches forward frames within a LAN based on MAC tables.

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.
