The document discusses the history and components of computers. It notes that the first mechanical calculator was invented in 1642 by Blaise Pascal and was later improved by Gottfried Leibniz to include multiplication. The first digital electronic computer was developed between 1937-1942 by John Atanasoff and Clifford Berry at Iowa State University, called the Atanasoff-Berry Computer. The modern definition of "computer" refers to a machine that can be programmed to carry out calculations. The document predicts that future computers will be able to simulate the sense of touch through sensors and transmit tactile feedback to users.

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.

Tells you about the History of computers. The various time periods in which the different types of computers were made by decreasing the size of the components used in the computers and increasing the various features in it.
evolution of computers
Since ancient times, humans have worked to develop tools to help with tasks like counting and calculations. The abacus, invented over 4,000 years ago in China, was one of the earliest counting devices, allowing easier addition and subtraction. Later inventions included Pascal's calculator in 1642, the first mechanical calculator; Leibniz's calculator in 1673, which could also multiply and find square roots; and Jacquard's loom in 1801, which used punch cards to automate patterns in textile production. These early electromechanical devices paved the way for computers.

FUNDAMENTALS OF COMPUTER lec 1.pptx
Charles Babbage is considered the father of computers. He invented the analytical engine, one of the first mechanical computers, in the 1830s-1850s. The analytical engine could perform basic mathematical functions. A computer is an electronic device that can perform complex tasks by breaking them into simple calculations. It takes input, processes it, and provides output. A computer system requires hardware, software, data, and users to function properly. It allows for fast, large-scale storage and processing of data, networking, and more efficient computing.

The document traces the evolution of computers from early counting devices like the abacus to modern computers. It discusses early mechanical calculators invented by Pascal and Babbage. The first programmable, general-purpose computer was ENIAC, built in 1946. Subsequent generations saw the replacement of vacuum tubes with transistors and integrated circuits, leading to smaller sizes. Modern computers are based on microprocessors and artificial intelligence. Computers have had widespread social impacts, both positive in areas like communication, and negative through issues like unemployment and data piracy.

This document discusses the history and development of computers from ancient counting tools to modern devices. It describes how early inventors like Blaise Pascal, Charles Babbage, and Herman Hollerith created early mechanical counting and data processing machines. It then discusses the first modern computers like the Mark I, ENIAC, and EDVAC, which were electric and used binary code. These innovations transformed computers from single-purpose machines into versatile general-purpose programmable devices.
History Of Computers
The history of computers began with early counting devices like the abacus. Over thousands of years, inventors created mechanical devices to help with calculations, including the Pascaline calculator and the Leibnitz calculator. The Jacquard loom used punch cards to automate weaving patterns. Charles Babbage designed analytical engines to perform calculations, and Herman Hollerith invented the punch card tabulator. Early electronic computers included the Mark 1, ENIAC, and EDVAC. Today's computers range from powerful supercomputers to personal computers like desktops, notebooks, and personal digital assistants.
History of the computer
Charles Babbage is considered the father of the computer. He began designing the difference engine in 1821. The abacus, invented over 5000 years ago in China, was one of the earliest devices used for calculation. The first generation of computers from 1940-1956 used vacuum tubes as their electronic technology. The ENIAC was the first electronic digital computer and used around 18,000 vacuum tubes. Transistors replaced vacuum tubes in the second generation from 1956-1963, and integrated circuits replaced transistors in the third generation from 1964-1971.
HISTORY OF COMPUTER.karl baroquillo.pptx
The document provides a history of computers from the 18th century to present day. It describes early mechanical calculating machines and how pioneers like Charles Babbage, Ada Lovelace, and Alan Turing contributed innovative ideas. Major developments included the first programmable computer by Atanasoff and Berry in 1941, the invention of the transistor in 1947, integrated circuits in 1958, the microprocessor in the 1970s, and the creation of personal computers in the 1970s led by Apple and IBM. The document traces the evolution of computers from specialized machines to ubiquitous technology and the development of operating systems, networking, software, and wireless connectivity.

- 1. COMPUTERS
- 2. INTRODUCTION • A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
- 3. HISTORY • The first mechanical calculator, a predecessor of the digital computer, was invented in 1642 by the French mathematician Blaise Pascal. That device was using a series of wheels of ten teeth in which each of the teeth was representing a digit from 0 to 9. The wheels were connected in such a way that they could add numbers making them advance the correct number of teeth. In 1670 the philosopher and mathematical German Gottfried Wilhelm Leibniz perfected this machine and invented one that also it could multiply.
- 4. INEVENTORS OF THE FIRST COMPUTERS ATANASOFF AND BERRY. A former patent of a device that great people believed that it was the first computer rigs l electronic it was invalidated in 1973 on order of a federal court, and officially the credit was given to John V. Atanasoff like the inventor. The Dr. Atanasoff, professor of the State University of Iowa, developed the first digital electronic computer between the years from 1937 to 1942. It called to his invention the computer Atanas off-Berry, ó alone ABC (Atanasoff Berry Computer). A graduated student, Cliffo rd Berry, him turned out to be a useful help in the construction.
- 5. COMPONENTS OF A COMPUTER
- 6. ETIMOLOGY • The first uses of the word "computer" was recorded in 1613 in to book called " The yong mans gleanings " by English writer Richard Braithwait I haue read the truest computer of Steal, and the best Arithmetician that euer breathed, and have reduceth thy dayes into to short number. It referred to to person who carried out calculations, or computations, and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its relative dwells meaning, to machine that carries out computations.
- 7. COMPUTERS IN THE FUTURE • In the future, as they indicate the specialized means of the United States that have had the opportunity to see more in depth this technology, the computers will be much more complete and the users will benefit from added options. When we touch an object on the tactile screen of a computer or of a tablet we will feel the tact of the component of factory with the one that has been created. The sensors of the computers are going to be capable of transmitting the same sensation that we feel the persons when we touch an object and notice the material with the one that has been created.
