Accepted Answer

Absolutely. The DBMS SQL Playground lets you write and execute real SQL queries (CREATE TABLE, INSERT, SELECT, JOIN, WHERE, GROUP BY, etc.) directly in your browser using the AlaSQL engine. No database server setup required — perfect for DBMS lab practicals.

Question 5

Which CPU scheduling algorithms does Bunk & Learn Hub support?

Accepted Answer

The CPU Scheduling Visualizer supports First Come First Serve (FCFS), Shortest Job First (SJF), Priority Scheduling (preemptive and non-preemptive), and Round Robin (RR) with customizable time quantum. It displays animated Gantt charts, waiting time, turnaround time, and completion calculations.

Question 6

Can I use Bunk & Learn Hub for SRMU lab practicals?

Accepted Answer

Yes, Bunk & Learn Hub is specifically designed for B.Tech CS students at Shri Ramswaroop Memorial University (SRMU) Lucknow. It covers all major lab subjects: Operating Systems, DBMS, Data Structures, Computer Networks, and Computer Fundamentals — making it ideal for lab practice and exam preparation.

Question 7

Does Bunk & Learn Hub have a Linux Terminal simulator?

Accepted Answer

Yes. The Linux Terminal Simulator lets you practice common bash/shell commands (ls, cd, mkdir, cat, grep, chmod, etc.) in a simulated environment within your browser. It's perfect for learning Linux basics for your OS lab without needing a VM or dual-boot setup.

Question 8

What data structures can I visualize on Bunk & Learn Hub?

Accepted Answer

You can interactively build and traverse Binary Trees (Inorder, Preorder, Postorder, Level-order), visualize Graph Algorithms (BFS, DFS, Dijkstra's Shortest Path), and explore Stack (LIFO), Queue (FIFO), and Memory Layout concepts with step-by-step animations.

Question 9

How is Bunk & Learn Hub different from other CS learning platforms?

Accepted Answer

Unlike platforms that only show theory or pre-recorded videos, Bunk & Learn Hub gives you hands-on, interactive simulations. You input your own data, watch algorithms execute step-by-step with animations, and get instant results. It runs 100% in the browser — no server, no login, no ads. It's specifically tailored for Indian B.Tech university syllabi, especially SRMU.

Question 10

What technology stack is Bunk & Learn Hub built with?

Accepted Answer

Bunk & Learn Hub is built with React 19, Vite 6, Tailwind CSS v4, and Lucide Icons. The DBMS Playground uses AlaSQL for in-browser SQL execution. It's a fully client-side Single Page Application (SPA) — all processing happens in your browser.
