Summary

A foundational overview of the client-server relationship, covering how requests travel from a client (browser) to a server through DNS resolution and network protocols.

Key Concepts

• The Relationship: Clients initiate requests; servers provide resources.
• DNS (Domain Name System): Translates human-readable domains (google.com) to IP addresses.
• Networking Basics:
  • IP Addresses: Unique identifiers for machines on a network.
  • Ports: Specific endpoints for different services on a single IP (e.g., Port 80 for HTTP, 443 for HTTPS).
• Communication Flow:
  1. Client requests IP via DNS.
  2. Client establishes connection to Server IP:Port.
  3. Communication occurs via Protocols (HTTP/HTTPS/TCP).

Notes

• Servers are essentially high-performance computers optimized for handling many concurrent requests.
• The separation of concerns allows for scaling the server side independently of the client.
