Semiconductors = Semiconductors

Simplified Definition:
Semiconductors are a material (most famously silicon) from which chips are made containing transistors that function as tiny precise switches: they open and close electricity flow at enormous speeds, and this is what makes computing, communications, and artificial intelligence possible.

What does it mean for you?

They are found in virtually everything: your phone, your car, the router, medical devices, and smart home devices.
When their supply chains break down, products may be delayed or prices may rise—because the chip is a small but "bottleneck" part in manufacturing.

Frequently Asked Question:
Are semiconductors the same as "chips"?
Answer:
Very close: semiconductors are the material and technology, and chips are the final product (an electronic component) made from them that is installed inside devices.
