First Real Calculator
Blaise Pascal developed the first real calculator or an abacus. -
Punched Card is invented.
The first input to record data. -
Period: to
Early History
Time Period of Early History -
Analytical Engine
In 1837, Babbage described his analytical engine. It a programmable computer that occupied punch cards for input and a steam engine for power. -
Recording of Data
In the late 1880s, Herman Hollerith invented data storage on a medium that could then be read by a machine. -
Z1 COmputer
Kornard Zuse make a first freely that is able to program computer. -
Period: to
First Generation
The first computer used vacuum tubes for memory.
This computer generated a lot of heat and used a lot of electricity.
The input were the punched cards and paper tape.
The output were the printouts.
The example of the first generation computer is UNIVAC and ENIAC. -
Colossus Computer
The first electronic digital computer that can be program. It was developed for the British codebreak during the World War II. -
ENIAC was annouced to the public
Electrical Numerical Integrator And Calculator was the first computer. -
First Computer using Vaccum Tubes
Computers using vacuum tubes as their electronic elements. -
UNIVAC was built
UNIVAC is the second computer after the ENIAC which is built by America. -
FORTAN Computer
It a first sucessful computer that have a high level calculating language. -
Transistor Computer is built.
The transistors allowed computers to become faster and more energy-efficient than the first generation. -
Period: to
Second Generation
The second generation computer replaced vacuum tubes with transistors.
The transistors allowed computers to become smaller, faster, cheaper and more energy-efficient than the first generation.
The input is punched card and the output is printouts.
COBOL and FORTRAN are example of second generation computer. -
The Computer Chip
Jack Kilby and Robert Noyce invented a integrated circuit or known as the computer chip. -
The "Floppy" Disk
The floppy mean flexibility. The first time the disk is name floppy disk. -
Spacewar Computer Game
It was the first computer game invented. -
The integrated computer is built.
The computers can run any different applications at one time. -
Period: to
Third Generation
The integrated circuit is the component for the third generation computer.
The input and output for the third generation is keyboards and monitors.
Apollo Flight Computer is a examples of third generation computer.
The computers can run any different applications at one time. -
First Mouse Prototype
The first mouse is made by Douglas Englebart during the 60's. -
Period: to
Fourth Generation
The microprocessor brought the fourth generation of computers.
A single chip controlled the memory to input/output.
The examples of fourth generation computers are DEC 10, STAR 1000 and PDP 11.
The computers are very cheap, very small size, portable, reliable and no AC is needed. -
The first Apple computer
The first Apple computer is made by Steve Wozniak. -
Miscrosoft Windows
Miscrosoft work with Apple and stated a friendly war between those two.
