Client-Server Architecture Explained — Day 2 | Java Backend Course
Day 2 of the Java Backend Development + Spring Boot course. Day 1 introduced backend development at a high level — today we zoom into exactly how a client and a backend actually communicate.
In this video, you'll learn:
What a client really is (browser, mobile app, another backend service)
What a server is, conceptually — without the infrastructure noise
What a request and a response actually carry
The complete request-response lifecycle, step by step, using a real student-portal example
What happens inside a backend application when a request arrives
Why the backend sits between the client and the database (security, validation, business rules)
Two real examples: a login flow and creating a new student record
Where your Java code actually runs
How one backend can serve multiple clients — web, mobile, and other services — at once
This is Lesson 2 of a structured, beginner-to-advanced Java Backend course. No Spring Boot yet — we're building the conceptual foundation first.
