Charles Babbage was born on 26th December 1791 and died on 18th October 1871. He is best remembered now for originating the concept of a programmable computer. He is considered as "Father of Computer."
-
Ada Lovelace was born on 12th December 1815 and died on 27th November 1851. She is chiefly known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Machine. She is also often described as the world's first programmer.
-
The worlds first computers were "Human computers."
-
It was a proposed mechanical general-purpose computer designed by Charles Babbage. Charles Babbage started describing analytical machine in 1837.
-
The first Vacuum Tube was invented on November 16, 1904. It was designed by John Ambrose Fleming. Vacuum Tube is a device controlling electric current through a vacuum in a sealed container. The container is often thin transparent glass in a roughly ccylindrical shape.
-
The main component for the 1st Generation is Vacuun tubes. The input was punch cards and paper tapes. The output was printouts. The examples of the computer are UNIVAC and ENIVAC.
-
The starting of First Generation.
-
ENIAC (Electronic Numerical Integrator and Computer) was first designed by J. Presper Eckert and John Mauchly. It was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve a full range of computing problems.
-
Transistors were designed on December 16, 1947. It was designed by William Shockley. It is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit.
-
The UNIVAC (Universal Automatic Computer) was first delivered on 14th June, 1951. It was designed by J. Presper Eckert and John Mauchly. It is electronic digital stored-program computers. It is the first general purpose computer for commercial use.
-
The main component was Transistor. The input was punch cards. The output was printouts. The examples of computers are COBOL and FORTRAN.
-
The starting of Second generation.
-
The FORTRAN (Formula Translating System) first appeared in 1957. It was designed by John Backus. It is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
-
The Integrated Circuit was invented in 1958. it was designed by John Kilby. It is a set of electronic circuits on one small plate ("chip") of semiconductor material, normally silicon. This can be made much smaller than a discrete circuit made from independent components. Integrated circuits are used in virtually all electronic equipment today and have revolutionized the world of electronics.
-
The COBOL (Common Buisness Oriented Language) was developed in 1959. It was Developed by Grace Hopper. It is one of the oldest programming languages.
-
The first Handheld device was a scientific calculator. It was designed by Hewlett Packard. It is a small, portable, often inexpensive electronic device used to perform both basic and complex operations of arithmetic.
-
The main component is Integrated Circuit. The input is keyboards and monitors. The output is interfaced with an operating system.
The examples of computer are transistor. -
The starting of Third generation.
-
The Mouse was patented in 1970. It was designed by Douglas Englebart. It is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.
-
The main component was microprocessor. The input and output is central processing unit. Example of computer is GUI's, the mouse and handheld devices.
-
The starting of Fourth generation.
-
The GUI (Graphical User Interface) was introduced in 1984. It was designed by Douglas Englebart. It is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation.
