1. Basic Digital Systems
A digital system processes information using two states: on (1) and off (0). These simple signals are the building blocks of all modern electronics, like smartphones and computers. Think of it like a light switch---on or off---working together to perform complex tasks like calculations and running apps.
2. Basic Computer Components
Logic Gates -- The Decision Makers
Logic gates are like tiny judges that decide based on inputs.
AND gate: Both must be "on" to pass.
OR gate: Either can be "on" to pass.
Flip-Flops -- The Memory Keepers
Flip-flops are small lockers that hold one bit of data, either 0 or 1, until the system needs to change it.
Registers -- Short-Term Memory
