Study Notes

History of Computers

Abacus: The earliest mechanical calculating device, made from a wooden frame, metal rods, and sliding wooden beads. Divided into "Heaven" and "Earth" sections for numerical representation.
John Napier invented Napier Bones in 1617, a calculating device using rods to aid in arithmetic.
Blaise Pascal, at 19, invented Pascaline in 1642, recognized as the first mechanical and automatic calculator using gears for digit representation.
Gottfried Leibniz enhanced Pascaline in 1673 by creating the Leibniz Calculator, capable of multiplication and division operations.
Charles Babbage invented the Analytical Engine in 1833, considered the first mechanical computer that could solve mathematical problems using punch cards; known as the "father of the computer."

Generational Progression

First Generation (1940-1956): Utilized vacuum tubes for circuitry and magnetic drums for memory, relied on machine language (binary code).
Vacuum Tubes: Invented by John Ambrose Fleming, crucial for early electronic devices.
UNIVAC: Developed by J. Presper Eckert and John Mauchly, notable for being the first commercially produced digital computer.
Second Generation (1956-1963): Transitioned from vacuum tubes to transistors, which were invented in 1947 at Bell Labs. This generation introduced assembly languages for programming.
Transistor: Demonstrated in 1947, crucial for replacing vacuum tubes. Inventors include William Shockley, John Bardeen, and Walter Brattain.
Third Generation (1964-1971): Characterized by integrated circuits, combining transistors on silicon chips, enhancing speed and efficiency.
Fourth Generation (1971-Present): Inception of microprocessors, integrating thousands of circuits on a single chip. The Intel 4004 was the first microprocessor released in March 1971. IBM introduced its personal computer (IBM 5150) in 1981 and Apple's Macintosh in 1984.
Fifth Generation (Present-Beyond): Focus on artificial intelligence and technologies like quantum computing, aiming to create devices that learn and respond to natural language.

Computer Capabilities

Speed: Significantly faster than humans in completing tasks, processing information in fractions of seconds.
Accuracy: High precision in calculations, although persistent errors in records can arise if programmed incorrectly.
Reliability: Designed for repetitive tasks with consistent performance, though system failures can occur.
Adaptability: Capable of handling diverse tasks, from simple to complex, unless purposefully limited.
Storage: Ability to store vast amounts of data efficiently within minimal physical space.

Limitations of Computers

Lack of Common Sense: Operate based solely on programmed instructions, lacking the intuitive reasoning skills of humans.
Zero IQ: Computers do not possess intelligence in the human context; they function according to algorithms and data inputted.
Dependence on Human Input: Require human guidance and control to function effectively, unable to make independent judgments or decisions.
