INTERACTIVE LEARNING

Prem's Labs

This page is under development, I will be adding more fun and interactive labs.

Computer Science & Data

01

Binary / Hex Playground

Visualize bits, bytes, and two's complement. Convert between bases and apply bitwise operations interactively.

Systems Architecture

02

CPU Pipeline Simulator

Explore a 5-stage instruction pipeline. Visualize data hazards, forwarding, and stalls.
03

Virtual Memory Simulator

Trace virtual address translation through TLBs and Page Tables to Physical Memory.
04

CPU Cache Simulator

Simulate direct-mapped and associative caches. Observe temporal and spatial locality.

Networking

05

CIDR / IPv4 Subnet Lab

Manipulate IP addresses and prefix lengths. Visualize subnet masks, broadcast addresses, and binary network boundaries.
06

TCP Three-Way Handshake

Step through the TCP state machine. Inspect SYN, ACK, sequence numbers, and connection establishment.
07

TCP Congestion Control

Simulate cwnd, slow start, and congestion avoidance. See how timeout and triple duplicate ACKs behave.
