Explain client vs serverDescribe DNS lookupName HTTP methodsRead HTTP status codes📚 Quick Recap
🎯 What you'll practice: The client-server model, DNS resolution, HTTP methods, and status codes.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1DNS is responsible for:
2Which HTTP method creates a new resource?
3Status code 404 means:
4The browser in the client-server model is the:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5Status code means the request succeeded.
6The HTTP method used to update an existing resource is or PATCH.
7List, in order, the five steps between typing a URL and seeing a page.
8What's the difference between PUT and DELETE?
9Why does a browser need an IP address, not just a domain name, to connect to a server?
🚀 Section C · Challenge ● CHALLENGE 5
10A user reports "the page won't load." Walk through the request/response cycle and list two different points where it could fail.

1-B 2-B 3-C 4-B | 5 = 200 6 = PUT 7 = DNS lookup, TCP connection, HTTP request sent, server processes and responds, browser renders 8 = PUT replaces/updates a resource's data, DELETE removes the resource entirely 9 = Because networking (TCP/IP) routes data using numeric IP addresses, not human-readable names — DNS exists to bridge that gap | 10 = Possible failure points: DNS lookup fails (bad domain), or the server itself is down/returns an error — could also mention TCP connection timeout or a client-side network issue.
