History of computer

Introduction

Past of centuries, man has always become the computer with no separation but now man has develop an amazing machine to help us calculate and almost do evry days work, this machine called computer. Computer has randomly transform to a much better system and high capability to do lots of work and to ease humans work. From the size of the hall to a simple device size of a palm, computer has been tremendous achivement of what human can do. We take look to a journey where computer has evolve through time.


Timeline

1936- (1) Konrad Zuse has build the Z1 computer which is the first freely programmable computer to been made. (2) Through this machine lots of discovery have been made which majorityly are mathematical discovery since it is the 1st and the only binary computer at that time, such as floating-point arithmetic and many more. Also after the Z1 prototype have been made,more Z's prototype came out from Z2 until Z4.

1942-(1) John Atanasoff and Clifford Berry build the ABC computer. (3) It was the first computer to use capacitors, vacuum tubes, binary numbers and electricity.

1944- (1) Howard Aiken and Grace Hopper invented the Mark 1 computer. (4) It weight 5 ton contains about 760,000 diffenrent separate parts. Mark 1 computer used by the US navy to calculate balistic and gunnery purposes.

1946- (1) John Presper Ekert and John W. Mauchly invented the ENIAC 1 computer. (5) ENIAC stands for Electrical Numerical Integrator And Calculator. This project was sponsored by US military as this computer for military purposes.

1948- (1) On this year Frederic Williams and Tom Kilburn invented Manchester Baby computer and the Williams Tube. Both invention cam form The University of Manchester. (6) This computer is the first computer to had all components of a computer which is what we call today characteristic of a basic computer.

1947/48- (1) John Bardeen, Walter Brattain and William Shockley invented the transistor. Though the transistor is a small device function to control flow of current and ability to let flow or not to let flow of current, still the transistor has impact on the future of computer.

1951- (1) On this year, John Presper Eckert and John W. Mauchly created the UNIVAC computer. (7) UNIVAC stands for Universal Automatic computer.

(P9) UNIVAC computer

1953- (1) IBM, a computer company developed and build the International Business Machines called IBM 701 EDPM computer. On this year also begin the era of IBM in computer history.


1955- (1) Stanford Research Institue collaboration with Bank of America and General Electric build ERMA and MICR. It was the first bank industry computer. MICR stands for Magnetic Ink Character Recognition. MICR functioned for checks reader. (8) ERMA stands for Electronic Method Reading of Accounting.

1964- (1) Douglas Engelbart invented the windows and computer mouse. It is called mouse because it has a wire coming out of the end of the mouse.



1970-(1) Intel 1103 computer were invented. It is the world's first available dynamic RAM chip.

1971- (1) On this year, Faggin, Hoff and Mazor invented the Intel 4004 computer microprocessor. It is the first microprocessor been made. Also on this year, Alan Shugart with IBM have invented the floppy disk. It is called floppy because of its flexibility.

1974/75- (1) During this year, the very first consumer computer were invented such as Mark-8 Altair and IBM 5100 computer.

1981- (1) IBM invented the IBM PC-Home computer. This has spark more personal computer to be created.


1983- (1) Apple unleashed the Apple Lisa computer. It was the first computer with GUI, graphical user interface.

1984- (1) Apple created another computer with GUI but more affordable, the Apple Macintosh.
