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.
