Here's why:
* Transistors are the fundamental building blocks of modern electronics. They act like tiny switches, controlling the flow of electricity.
* CPUs perform calculations and process data. They do this by manipulating electrical signals, and transistors are the essential components for performing these manipulations.
* The complexity of a CPU is immense. A single CPU can have billions of transistors arranged in intricate circuits to carry out complex instructions.
Think of it like this:
* A single transistor is like a single light switch.
* A CPU is like a massive building with billions of light switches, all connected in a complex network.
Each switch can be turned on or off, and the combination of on/off states across the entire network determines what the CPU does.
