🔰 Prerequisites for Learning Cloud Computing

🌐 1. Networking

Networking refers to the connection of computers and other devices to share data and resources like the internet, printers, files, and applications.

Key Concepts:

• LAN (Local Area Network) – small area (e.g., home or office)

• WAN (Wide Area Network) – large area (e.g., the internet)

• IP Address – unique number given to each device in a network

• Router/Switch – devices that manage connections between computers

• Protocols – rules for communication (e.g., TCP/IP, HTTP)

📌 Example: When you send an email or browse a website, you’re using networking.

• Firewalls: Block unauthorized network access

• Encryption: Scrambles data to protect it

• User Permissions: Limit access based on roles

📌 Example: Using two-step verification (OTP + password) to log into your email.
