-
The Early History- when computers are't exactly the computer nowadays and people/simple machinese are used to calculate maths. The first "computers" refer to humans doing maths
-
Ada Lovelace, a mathematician and writer collaborated with Charles Babbage to make the Analytical Engine. She was credited as world's first programmer
-
Charles Babbage tried to make a programmable machine/difference engine used to do math equations, but only maid a few parts before he died
-
Punch cards' easy to use codes and holes used replaces Census (people counting and recording population) to caluculate America's rapid pupulation.
-
The first generation computers, where machines use vacuum tubes which are used to give signals and switch on/off "computers"/machines. It uses lots of light.
-
The colossus was the world's first digital computer. It was used by the British people to decode German messages. Colossus used vacuum tubes to make calculations.
-
Second Generation - More reliable Transistors used instead of vacuum tubes. Transistors are much smaller and doesn't produce as much light as vacuum tube does.
-
ENIAC, was the first general purpose computer was created, it was said to use 18,000 vacuum tubes. It was designed to calculate things for the U.S.'s Ballistic Research Labatory
-
First computer for Commercial use, UNIVAC, or Universal Automatic Computer, is created. It's made by the Eckert-Mauchly Computer Corporation.
-
The International Business Machines Corporation gave IBM 650 and 700, one of IBM's earliest computers to the world. They were used for Engineers and people who use Punch Card Machines
-
Third Generation- EVEN smaller Integrated Circuit replaces Transistors to give computers informations
-
The Space Race between Russia and USA popularized the expensive integrated circuit, which allowed USA to beat the Russians to Space.
-
The current generation, where we use microprocessors to give signals and computer now have Graphical User Interphace. Computers now have lots of purposes, too.
-
Xerox was the first to make computers with graphical user interphace, which made using computers a lot more easier, since you do not need to remember codes anymore.
-
IBM made a personal computer, or PC for office. With this computer the word PC is used for home computers and personal computers.
-
Xerox made the first Commercial computer with graphical user Interphace, which makes things easier when using computers.
-
Apple Macintosh, the first famous computer made by Apple with Graphical User Interphase.I costed US$2,495, and is the first computer to be on the Mac line
-
This is Microsoft's first computer with Graphical User Interphace, which was created after Bill Gates paid a visit to Apple and saw the Graphical User Interphace
-
Apple and Microsoft began a war with each other, selling out new products while Apple tries to sue Windows for "stealing" the Graphical User Interphase
