HISTORY OF THE COMPUTER
The document summarizes the history of computers, beginning with early counting methods using stones, pebbles, fingers and marks. It then discusses the abacus as the first mathematical device for calculations, invented by the Chinese over 5,000 years ago. Later inventions included Napier's Bones, Pascal's mechanical calculator, and Babbage's Analytical Engine, which had elements of a modern computer and established Babbage as the father of the modern computer.

History of computers
Humans have performed arithmetic calculations since prehistoric times using methods like counting on fingers. The development of number systems allowed early civilizations to track astronomical cycles and business dealings, giving rise to the concept of "computing". As calculating tools advanced from manual to electronic methods, the first computers emerged. During the early stages of development, notable calculating machines included Napier's Bones for multiplication, the slide rule, Pascal's rotating wheel calculator, Babbage's Difference Engine, and Hollerith's punched card tabulating machine. These inventions marked progress toward the electronic computers of today.
History of computers
The history of computers began with early calculating devices like the abacus. In the 17th-18th centuries, people developed mechanical aids for calculation like the slide rule. The first true calculating machines appeared in the 19th century using gears. Charles Babbage designed an "Analytical Engine" in the 1830s but it was never completed. In the 20th century, digital computers were developed using vacuum tubes and transistors, leading to generations of increasingly faster computers using integrated circuits. Today's fourth-generation computers are 50 times faster than third-generation computers.

It provides details on inventors and inventions that marked milestones in computing such as Babbage, the Analytical Engine, the transistor, microprocessor, and GUI.
Computer history timeline
The document outlines the key developments in computer history from ancient calculating devices like the abacus to modern personal computers. Some of the earliest developments included the abacus (3000 BC), Pascaline mechanical adding machine (1642), and punched cards for data storage in the 1800s. Major milestones were Charles Babbage's analytical engine (1830s), the first general purpose computer Mark 1 (1944), the electronic ENIAC (1946), and the first commercial computer UNIVAC (1951). Personal computing began with the Apple II (1977) and IBM PC (1981) which led to portable computers in 1987 and multimedia desktop computers in the 1990s.
002-Computer-History.pptx
The document discusses the history and evolution of early computing devices from ancient times through modern computers. It describes how early computers were people who performed calculations before the invention of mechanical devices like the abacus. Early mechanical calculators were developed including the Pascaline in the 1600s and Babbage's Analytical Engine in the 1800s, though it was never fully built. The first general purpose electronic computers of the 1940s-50s used vacuum tubes, followed by transistors in the 1950s and integrated circuits in the 1960s which drove the development of smaller personal computers. Each generation of computers integrated newer electronic components and capabilities.
ICF.pptx
The document traces the evolution of computing devices, beginning with early counting tools like fingers and pebbles. It describes the abacus, the first known mechanical computing device, as well as Napier's bones and devices created by Blaise Pascal and Gottfried Leibniz to perform mathematical calculations. The document outlines key inventions like Joseph Marie Jacquard's use of punch cards to program textile looms and Charles Babbage's designs for early mechanical general-purpose computers. It also mentions Herman Hollerith's tabulating machine and the creation of the ABC computer by John Vincent Atanasoff and Clifford Berry, which used several principles found in modern computers.
History Of Computers
This document provides a history of the development of computers from ancient counting devices to early modern calculating machines and programmable computers. It describes inventions like the abacus, Napier's bones, the slide rule, Pascaline, Leibnitz calculator, Jacquard loom, Difference Engine, Analytical Engine, Tabulating Machine, and the Mark I - considered the first general purpose computer. These inventions progressively added capabilities like storage, programming, and automatic execution of programs to process data into useful information.

What is computer
The document discusses the history and evolution of computers from ancient counting devices like the abacus to modern digital computers. It begins with early mechanical calculators invented by Pascal and Leibniz in the 1600s. Important developments include Babbage's analytical engine design in the 1830s, Hollerith's tabulating machine used for the 1890 US Census, and the first programmable digital computer, the Harvard Mark I, built in 1944. The document then covers the five generations of computers from vacuum tube-based machines to today's portable devices and discusses different types of computers like mainframes, supercomputers, and analog versus digital systems.

- 15. Charles Babbage •The father of the modern computer. •Babbage is credited with inventing the first mechanical computer that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's Analytical Engine.
- 16. Analytical engine •It is considered the forerunner of the computer today. •It contained the essential parts such as : input unit, output unit , memory unit and processing unit.
- 17. Ada Lovelace • was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. • She was the first to recognize that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine.
- 18. Hollerith’s Tabulating Machine •Developed by Herman Hollerith. •Was the first electromechanical system for recording , compiling and tabulating data. It used punched cards to record data.
- 19. Mark I •Designed by Harvard researchers led by Howard Hathaway Aiken. •It was a collection of electromechanical calculators, it was used by the US Army for designing weapons during World War 2.
- 20. ABC •Assembled by John Atanasoff and Clifford Berry. •It is considered as the first automatic electronic digital computer. •It used many newly invented digital circuits designs.
- 21. ENIAC •Electronic Numerical Integrator and Computer •It was initially built for US military to calculate artillery shells and later used for nuclear weapons, weather predictions and tunnel designs.
- 22. EDVAC •Electronic Discrete Variable Automatic Computer, developed my Mauchly and Eckert. •The first digital computer that used a stored program to control the computer.
