Study Notes
Evolution of Computers
- The shift to electrical power in computing began in 1924, moving away from mechanical power.
Early Computers
- Late 1942: Atanasoff-Berry Computer (ABC) developed, recognized as the first electronic digital computer.
- 1944: IBM's Mark I, created by Howard Aiken, was unveiled.
- 1946: ENIAC, based on the ABC, was introduced as the first general-purpose computer.
First Generation (1951-1958): The Vacuum Tube
- 1951: UNIVAC 1 delivered to the US Bureau of the Census, marking its relevance for business applications.
- Utilized thousands of vacuum tubes, which posed challenges like heat issues and frequent failures.
- 1957: Magnetic tape storage was adopted for data management.
Second Generation (1959-1964): The Transistor
- Bell Labs developed the transistor, enhancing electronic devices' efficiency and size.
- Transistors were smaller, required no warm-up time, and consumed less power, increasing reliability.
- Transition from machine language to assembly language and high-level languages began.
- Computers primarily used by businesses, universities, and government entities.
Third Generation (1965-1970): The Integrated Circuit
- Integrated Circuits (ICs) allowed multiple electronic components to be placed on a single silicon chip.
- ICs started to replace transistors in 1965, contributing to significant size and efficiency improvements.
- More advanced software solutions emerged, allowing access to computers via terminals.
Fourth Generation (1971-Today): The Microprocessor
- Introduction of Intel's 4004 microprocessor, marked by general-purpose processing on a chip.
- Enabled the development of various digital devices like calculators and watches.
Fifth Generation (Today-Future): Artificial Intelligence
- AI research initiated by Japan’s MITI in the 1970s, focusing on high-level computations using parallel processing.
- 1981: Launch of IBM PC, the first mainstream personal computer.
- 1983: Apple Lisa was introduced as the first home computer to feature a graphical user interface (GUI).
- 1984: Apple Macintosh followed, further popularizing PCs.
Basic Components of a Computer System
- A computer accepts input data, processes it to create useful information, stores instructions and results, and produces final output.
Role of Information Technology
- IT supports managing information through modern technology for capturing, storing, retrieving, analyzing, and communicating data.
- IT spans various fields including education, finance, travel, government, manufacturing, health, and publishing.
Historical Context of Computing
- Early counting methods utilized physical objects (e.g., pebbles, marks).
- Charles Babbage proposed the analytical engine, incorporating features of modern computers such as input processing, storage, and output.
- Ada Lovelace, known as the first computer programmer, contributed to Babbage’s theoretical framework.
- Herman Hollerith invented a tabulating machine, revolutionizing the 1890 US census process, reducing counting time significantly, and later founded IBM Corp.
