Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the historical switching technologies?Included vacuum tubes, electromagnetic relays, and fluidic logic before widespread semiconductor use
2. What is the modern fabrication?Predominantly constructed using MOSFETs integrated onto silicon chips
3. How do logic gates help computers think?By connecting many logic gates together, computers can perform complex tasks like adding numbers or deciding which way to go. Each gate makes a small decision that helps the whole system work.
4. Why are MOSFETs used in modern logic gates?MOSFETs are very fast, use little power, and can be made very small, so they let millions of logic gates fit on one chip.

Boolean Algebra: A branch of algebra dealing with binary variables and logical operations such as AND, OR, and NOT.
Integrated Circuit (IC): A miniaturized electronic circuit consisting of many interconnected components fabricated on a single semiconductor substrate.
Arithmetic Logic Unit (ALU): A digital circuit within a processor that performs arithmetic and bitwise logical operations on integer binary numbers.
