Study Notes
History of Computers
- Early calculators like the abacus were used for basic math calculations, moving beads on a wooden rack.
- The abacus is still used today.
17th Century Calculators
- Pascal created a mechanical calculator to assist with his father's tax-collection calculations.
- This was a significant advancement, using gears to perform addition and subtraction.
- "Computer" initially referred to a person who performed calculations.
19th Century Calculating Engines
- Babbage's calculating engine was a complex machine with input, processor, memory, and output components.
- These components are still fundamental to modern computers.
- Further developments involved replacing mechanical parts with switches controlled by numbers, marking a key shift to "digital" technology.
- Ada Lovelace is the first computer programmer, writing sequences for future computers and predicted the digitalization of sound, music, text, and images.
20th-21st Century Computers
-
Early computers were large room-sized machines requiring teams to operate.
-
Limited to the Army and large organizations initially.
-
Computers became progressively smaller, faster, and cheaper over time.
-
Mass availability through PCs defined the 21st century.
-
Software development broadened and made computers more versatile.
-
