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. Who invented History of computing hardware?The transistor was invented at Bell Labs in 1947, enabling solid-state electronics
2. What is the babbage's analytical engine concept?Charles Babbage conceptualized a programmable mechanical computer in the 19th century
3. What is the ENIAC vacuum tube count?The ENIAC computer utilized approximately 17,468 vacuum tubes
4. What were the earliest computers like?The first computers were huge machines that used many vacuum tubes, like the ENIAC built in 1945. They were very large, used a lot of electricity, and needed cooling fans to keep them from overheating.
5. Why did computers get smaller after transistors were invented?Transistors were smaller, used less power, and produced less heat, so computers could be built with fewer parts and in a more compact space. This made them faster and cheaper.

Electromechanical Computer: Computers using both electrical and mechanical components for operation, like early tabulating machines.
Vacuum Tube: An electronic component used in early computers to control electron flow, characterized by size and fragility.
Transistor: A semiconductor device that amplifies or switches electronic signals, smaller and more reliable than vacuum tubes.
Integrated Circuit (IC): A miniaturized electronic circuit fabricated on a single semiconductor substrate, enabling complex functionality on a small chip.
