History of Computer
This document provides a history of computers from ancient counting devices to modern electronic digital computers. It discusses early mechanical calculating devices like the abacus and slide rule invented by John Napier. Blaise Pascal invented the first mechanical calculator called the Pascaline in 1642. Charles Babbage designed the Difference Engine and Analytical Engine, prototypes for the first automatic programmable computer. Herman Hollerith developed the first electro-mechanical punch card tabular in 1890. John von Neumann's work in the 1940s established the architecture for modern computers. The first general-purpose electronic digital computers, ENIAC and UNIVAC, were completed in 1946 and 1951 respectively.

1. It defines a computer as an electronic device that accepts data as input, processes it, and provides the desired output. The basic functions of a computer are input, processing, output, storage, and control.
2. Early calculating devices included the abacus and Napier's bones. Modern computers have evolved from machines like Pascal's calculator through generations using different technologies like vacuum tubes, transistors, integrated circuits, and microprocessors.
3. Computers are classified based on their size and capabilities as microcomputers, minicomputers, mainframes, and supercomputers. The basic components of a computer are the input, output, central processing unit
Computer system
A computer system consists of hardware, software, and data. It is a collection of related components designed to work together. Hardware refers to the physical parts of the computer like the computer itself and peripherals. Software includes the programs that run the computer like operating systems and applications. Data are unprocessed facts, while information is processed data. Common components of a computer system include input devices, processors, and output devices. Popular software categories are system software that controls the computer and application software for specific tasks. Common platforms are Windows operating systems paired with Intel processors.

Chapter 1.pptx
The document provides an overview of computers including definitions, historical developments, generations, classifications, components, characteristics and applications. It defines a computer as a programmable device that processes data according to instructions to perform tasks. Early computers included the abacus, Pascaline and Babbage machines. Generations progressed from vacuum tubes to transistors to integrated circuits. Computers can be classified by the type of data they process or their size/capacity. Key components are hardware and software. Computers are fast, accurate, automatic and versatile. Main applications are in commercial, scientific, education and manufacturing fields.
Computer basics
The document provides a history of computers from ancient counting devices like the abacus to modern computers. It describes inventions like the Pascaline adding machine in 1642, Charles Babbage's analytical engine in 1833, Howard Aiken's Mark 1 in 1944, the ENIAC in 1946, the first transistor in 1948, the Altair kit computer in 1975, the IBM PC in 1981, and the Macintosh in 1984. It also provides overviews of different types of computers including PCs, workstations, mini computers, mainframes, and supercomputers. The document outlines the basic functions and advantages of computers as well as some disadvantages.
UNIT 1 FOC.pptx
The document provides a history of computer programming and early computers. It discusses how calculations were originally performed by human "computers" and the earliest devices like the abacus and tally sticks. Some of the earliest mechanical computers were Charles Babbage's Difference Engine and Analytical Engine in the 1830s-40s. Augusta Ada Byron wrote programs for these, making her the first computer programmer. The document then outlines the development of early electronic computers like the ENIAC, UNIVAC, and EDVAC in the 1940s-50s, as well as the first portable computer, generations of computers, and classification of computers by size, purpose, and type.

How to Fix the Import Error in the Odoo 17
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.

- 7. THE LANGUAGE OF COMPUTERS
- 8. Binary Numbers 1 and 0 ‘s Computers speak binary. Binary language consists of combinations of 1's and 0's that represent characters of other languages (in our case the English language). Don’t make the mistake of thinking that little 1's and 0's are running around inside of the computer. We humans prefer to think of 1's and 0's because it’s easier than visualizing positive and negative current flows or open and closed circuits which is what actually happens inside computers. A combination of eight bits represents one character in our language. One character in our language (eight bits) is referred to as a byte. (For example: 01000001 is a byte that represents an uppercase A; each 1 or 0 is a bit.)
- 9. 9history.ppt 21-Jan-03 Binary Numbers Kilobytes, Megabytes, and Gigabytes If you understand that a byte is one character in our language, you’ve got it made because: 1000 bytes = 1 kilobyte (1,000 characters = 1 kilobyte) 1,000,000 bytes = 1 megabyte (1,000,000 characters = 1 megabyte) 1,000,000,000 bytes = 1 gigabyte (1,000,000,000 characters = 1 gigabyte)
