-
Blaise Pascal developed the first real calculator or an abacus.
-
The first input to record data.
-
Time Period of Early History
-
In 1837, Babbage described his analytical engine. It a programmable computer that occupied punch cards for input and a steam engine for power.
-
In the late 1880s, Herman Hollerith invented data storage on a medium that could then be read by a machine.
-
Kornard Zuse make a first freely that is able to program computer.
-
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. -
The first electronic digital computer that can be program. It was developed for the British codebreak during the World War II.
-
Electrical Numerical Integrator And Calculator was the first computer.
-
Computers using vacuum tubes as their electronic elements.
-
UNIVAC is the second computer after the ENIAC which is built by America.
-
It a first sucessful computer that have a high level calculating language.
-
The transistors allowed computers to become faster and more energy-efficient than the first 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. -
Jack Kilby and Robert Noyce invented a integrated circuit or known as the computer chip.
-
The floppy mean flexibility. The first time the disk is name floppy disk.
-
It was the first computer game invented.
-
The computers can run any different applications at one time.
-
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. -
The first mouse is made by Douglas Englebart during the 60's.
-
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 is made by Steve Wozniak.
-
Miscrosoft work with Apple and stated a friendly war between those two.
