Study Notes

History of Computers

Five generations of computers span from 1946 to today, each marked by significant technological advancements.

First Generation (1946-1958)

Utilized vacuum tubes for circuitry and magnetic drums for memory.
Operated using machine language, solving one problem at a time.
Input methods included punched cards and paper tape; output displayed on printouts.
Large physical size, often occupying entire rooms.

Second Generation (1959-1964)

Transistors replaced vacuum tubes, improving size, speed, reliability, and energy efficiency.
One transistor could replace 40 vacuum tubes, although heat generation remained a concern.
Transitioned to assembly language for programming, moving away from cryptic binary.
Stored instructions in memory using magnetic core technology.
Still relied on punched cards for input and printouts for output.

Third Generation (1965-1970)

Marked by the development of integrated circuits that combined multiple transistors onto a single chip.
Enabled user interaction through keyboards and monitors, supported by operating systems.
Operating systems allowed simultaneous execution of multiple applications.
Computers became smaller and more affordable, reaching a broader audience.

Fourth Generation (1971-present)

Introduction of microprocessors, integrating thousands of circuits into one chip.
Capable of networking, leading to the development of the Internet.
Emergence of graphical user interfaces (GUIs), mice, and handheld devices.

Fifth Generation (Present and Future)

Focused on Artificial Intelligence (AI) development, incorporating parallel processing and superconductors.
Emphasis on natural language processing and devices capable of learning and self-organization.
Existing applications include voice recognition technology.

Notable Computers and Innovations

ENIAC: Considered one of the earliest computers; developed by Eckert and Mauchly.
UNIVAC I: First commercial computer, designed by Eckert and Mauchly.
EDVAC: The first stored program computer, designed by Von Neumann in 1952, capable of holding both program and data.
Osborne 1: The first portable computer, released in 1981.

Pioneers in Computing

Electronic Controls Company: Founded by Eckert and Mauchly in 1949, recognized as the first computer company.
