The Dojo
Pick a simulator and start operating the algorithm. The two free ones are fully interactive — the rest unlock with the ₹499 pack and ship on a monthly cadence.
CPU Process Scheduling
Run FCFS, SJF, Round Robin & Priority on live process queues. Watch the Gantt chart build itself.
Memory & Page Replacement
Step through FIFO, LRU & Optimal page replacement. See faults, hits and frame state per reference.
Disk Scheduling
FCFS, SSTF, SCAN & C-SCAN head movement on a live cylinder track.
Deadlock & Banker's Algorithm
Allocate resources and test for safe sequences. Watch the system avoid deadlock.
Packet Routing
Route packets across a topology with Dijkstra & distance-vector. See the routing tables converge.
TCP & Congestion Control
3-way handshake, sliding window, slow start vs congestion avoidance.
Subnetting & CIDR
Carve networks, compute masks & hosts, generate infinite subnetting drills.
SQL Query Planner
Build a query plan: see scans vs index seeks, joins & cost estimates.
B-Tree Indexes
Insert & split keys in a B-tree; watch the index rebalance live.
Transactions & Locking
ACID, isolation levels, 2-phase locking and dirty/phantom reads.
Sorting & Complexity
Race quick/merge/heap sort, count comparisons, feel Big-O.
Graph Traversal
BFS, DFS, Dijkstra & A* on a grid you draw yourself.
