History Of Computers Flashcards
A man considered as father of computer
Charles Babbage
It is a miniature semiconductor that regulates or controls current or voltage flow
Transistors
He is a British mathematician that introduced the concept of the Turing Machine.
Alan Turing
Charles Babbage developed the idea of mechanical computing devices known as the……
Analytical engine
A mathematician has writing the first computer program for Babbage’s machine.
Ada lovelace
It is a device that utilizes electronic technology, especially microelectronic technology, to perform complex calculations and aid in various tasks such as design, manufacturing and testing.
Electronic computers
It was built in 1945 considered as first general-purpose electronic computer.
Electronic Numerical Integrator and Computer (ENIAC)
It is a small chip that contains a collection of transistors, resistors, and capacitors integrated into a single unit.
It functions as a complete electronic circuit, enabling the processing and storage of data.
Integrated circuits
It is a computer designed for individual use. It is typically used for tasks such as word processing, Internet browsing, email, multimedia playback, and gaming.
Personal Computers (PC)
A compact electronic device that serves as the Central Processing Unit (CPU)
Microprocessor
Display format that allows the user to select commands and programs, and do other routine tasks.
Graphical User Interface (GUI)
It was the first operational packet switching network and the precursor to the modern Internet and developed by the U.S. in the late 1960s to improve communication and collaboration among researchers.
Advanced Research Projects Agency Network ( ARPANET )
It was created by Tim Berners-Lee in 1989
World Wide Web ( WWW )
It is a system of interconnected documents and multimedia accessible via the Internet using web browsers.
It utilizes hypertext links to connect information, allowing users to navigate between Web pages.
The Web
The Web operates through three main technologies:
●HTML ( for content structure )
HyperText Markup Language
●HTTP ( for data transfer )
HyperText Transfer Protocol
●URLs ( for addressing resources)
Uniform Resource Locator
Process of creating and maintaining software where the source code is publicly available and developed collaboratively by a community of developers.
Open Source Software Development
It refers to computer systems designed to perform tasks that traditionally require human intelligence, such as reasoning, decision-making, and problem solving.
Artificial Intelligence (AI)
It is a subset of AI that focuses on the development of algorithms that allow computers to learn from and make predictions based on data.
Machine Learning
Invented in 1623 by Mathematician and Astronomer Wilhelm Schickard.
It uses Napier Bones for Multiplication and Division, and a Toothed-wheel system for addition subtract.
Schickard’s Calculating Clock
Invented in 1642 by a French mathematician Blaine Pascal.
It is a toothed-wheel system that allows to Add and Substract numbers through the use of dials in which will add a number when turn clockwise and counter clockwise when subtracting.
Pascaline
It is also called Leibniz’s Calculator invented by German Mathematician Gottfried Wilhelm Leibniz.
It allows to do 4 basic operations instead of 2 by a rotating cylinder that allows to do addition and subtraction repeatedly.
Stepped Reckoner
Designed by Mathematician Pioneer Charles Babbage.
It is a steam powered machine that allows to do calculations automatically.
It is considered the first computer ever invented.
Analytical Engine
Invented by Herman Hollerith in 1884.
The machine stores data by holes being punched on a strip of paper then later switches on to punched cards being holed using a hole puncher (pantograph) in 1886
Tabulating machines
An electric device that uses vacuum (or valves) as an insulator to shield against electric currents.
Vacuum tube computers
