Augusta Ada Byron’s work with Babbage is most notable because she:

• Designed a physical machine
• Wrote the first algorithm intended for processing
• Used a light pen interface
• Invented binary code

Answer explanation

Ada is considered the first computer programmer.

Which best reflects Charles Babbage’s concept of the Analytical Engine?

• A calculator with only arithmetic functions
• A mechanical device for typewriting
• A general-purpose programmable machine
• A digital transistor circuit

Answer explanation

The Analytical Engine could be programmed to solve any mathematical problem.

Napier’s Bones contributed to computational efficiency by:

• Converting binary to decimal
• Reducing complex algebra to geometry
• Transforming multiplication/division into addition/subtraction
• Generating pseudocode

Answer explanation

Napier’s Bones simplified multiplication using addition tables.

The introduction of Boolean Algebra directly influenced:

• The creation of the internet
