Study Notes
First-Generation Computers
- Major innovation: Introduction of vacuum tubes for circuitry, replacing mechanical switches.
- ENIAC (Electronic Numerical Integrator and Computer), built in 1946, was utilized during World War II for military calculations.
- UNIVAC I was the first general-purpose electronic digital computer designed for commercial use.
Disadvantages of First-Generation Computers
- Large physical size and high power consumption.
- Generated significant heat, leading to reliability issues.
- Programmed in machine language, making programming complex.
Second-Generation Computers
- Major innovation: Use of transistors, which were smaller, more reliable, and energy-efficient compared to vacuum tubes.
- Magnetic core memory technology was used for data storage, increasing speed and efficiency.
Father of Computing
- Charles Babbage is recognized as the father of computing due to his foundational work in early mechanical computers.
Difference Engine
- Designed to automate polynomial calculations, intended for producing mathematical tables.
Analytical Engine
- Built in the mid-1800s, although it was never completed during Babbage's lifetime.
- Capable of performing 60 additions per minute.
- Composed of five units: the mill (for arithmetic operations), store (memory), control (operator), input, and output.
Operations of the Analytical Engine
- The mill unit was specifically used for performing arithmetic operations, such as addition and multiplication.
