Basic Computer Logic Circuit
Main Idea: This transistor circuit is the foundation of all computer logic - it's basically a switch controlled by electricity!
How It Works
Input Signal → Transistor → Output Signal
Small voltage IN controls Large current OUT
Computer Connection
- Binary Logic: Input HIGH = Output ON, Input LOW = Output OFF
- Digital Gates: Multiple transistors create AND, OR, NOT gates
- Memory: Transistors can store 1s and 0s
- Processing: Millions of these switches do calculations
Input: 0V (OFF) → Output: LOW
Input: 5V (ON) → Output: HIGH
Key Components
- Transistor: The electronic switch
- Base: Control input (like a light switch)
- Collector/Emitter: Main current path
- Resistors: Control current flow
Bottom Line: Your computer has billions of these tiny switches working together to process information, run programs, and display this text!
This simple circuit is the building block of all digital technology
