CS Concepts
Interactive exhibits — switch things on, break them, and watch what happens. Each exhibit gets the full page to itself; the GCSE / A-Level switch is inside each one.
- GCSEA-LevelBoolean logic & logic gatesAND · OR · NOT · NAND · NOR · XOR · XNORToggle inputs, watch signals flow, build circuits from 2 to 4 gates
- GCSEA-LevelBinary & hexadecimalBits, nibbles, overflow, pixels and soundFlip bits and watch every representation update
- GCSEA-LevelThe memory hierarchyRegisters → cache → RAM → secondary storageFollow the data — then switch the power off
- GCSEA-LevelNetworkingFollow a packet from client to serverSwitches, routers, IPs and MACs on one journey
- GCSEA-LevelCybersecurityCipher · hashing · brute force · firewall · phishingFive safe, hands-on security simulations
- GCSEA-LevelThe fetch–decode–execute cyclePC · MAR · MDR · CIR · Accumulator · CU · ALUWatch one instruction travel the whole machine, step by step
