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 primary mechanism?Physical gears, levers, cams, and linkages for computation
2. What is the categorization?Analog (continuous physical quantities) and Discrete (step-by-step mechanical actions)
3. How did mechanical computers help in World War II?They were used in bombsights and ship fire control to calculate where to aim, making bombing and naval attacks more accurate.
4. Why did mechanical computers stop being used?Electronic computers became faster, smaller, and cheaper, so people switched to them.

Analog Computation: Computation using continuous physical quantities to represent numerical values, like a slide rule.
Discrete Computation: Computation performed through distinct, sequential mechanical steps or states, like gear rotations.
Differential Analyzer: A complex mechanical analog computer designed to solve differential equations, a precursor to modern scientific computing.
Norden Bombsight: A highly accurate World War II bombsight that incorporated a sophisticated mechanical computer for aiming calculations.
