Featured Simulations

Change the variables. See what happens. Learn by doing.

Blocking vs Non-Blocking I/O Simulator

Explore how blocking and non-blocking I/O handle the same workload. Adjust requests, worker counts, and I/O timing, then compare thread states, queues, and execution timelines.

Context Switching Simulator

Experiment with process counts, time quantum, context-switch cost, and I/O frequency. Observe how scheduling decisions change the execution timeline, switch counts, and CPU efficiency.

Loan and interest simulation comparing borrowing costs, savings growth and after-tax interest.

Loan & Interest Simulator

Compare loans, mortgages and credit card interest, or explore deposits and monthly savings. See schedules, interest and optional after-tax estimates.

Currency exchange simulation comparing conversion routes, fees, and final amounts.

Currency Exchange and Fee Simulator

Adjust exchange rates, amounts, percentage fees, and fixed fees across direct or two-step currency routes. Explore rate sensitivity, compare scenarios, and manually save results with both graphs to Funify Notes.
