FC: computers | the beginning middle and end

1: The term Computer, originally meant a person capable of performing numerical calculations with the help of a mechanical computing device. The foundation stone of the development of computers was laid way back in the era before Christ. Binary arithmetic is at the core of computer systems. History of computers dates back to the invention of a mechanical adding machine in 1642. ABACUS, an early computing tool, the invention of logarithm by John Napier and the invention of slide rules by William Oughtred were significant events in the evolution of computers from these early computing devices. Here's introducing you to the ancestors of modern computers.

2: It is a little hard to determine what was the first portable or laptop computer, the first portable computers did not look like the book-sized and folding laptops that we are familiar with today, however, they were both portable and lapable, and lead to the development of notebook style laptops. I have outlined several potential firsts below and how each qualifies, many of the off-site links provide good photos of the computers that will let you see the progression in design. The First Laptop? Maybe Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980's. A 340K byte bubble memory lap-top computer with die-cast magnesium case and folding electroluminescent graphics display screen.the first laptop looked something like...........

3: Hewlett-Packard is Founded. David Packard and Bill Hewlett found Hewlett-Packard in a Palo Alto, California garage. Their first product was the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers. Walt Disney Pictures ordered eight of the 200B model to use as sound effects generators for the 1940 movie “Fantasia.” | Xerox Corp. bought Scientific Data Systems for nearly $1 billion — 90 times the latters earnings. The SDS series of minicomputers in the early 1960s logged more sales than did Digital Equipment Corp. Xerox changed the series to the XDS computers but eventually closed the division and ceased to manufacture the equipment. | Intel released the 80486 microprocessor and the i860 RISC/coprocessor chip, each of which contained more than 1 million transistors. The RISC microprocessor had a 32-bit integer arithmetic and logic unit (the part of the CPU that performs operations such as addition and subtraction), a 64-bit floating-point unit, and a clock rate of 33 MHz. The 486 chips remained similar in structure to their predecessors, the 386 chips. What set the 486 apart was its optimized instruction set, with an on-chip unified instruction and data cache and an optional on-chip floating-point unit. Combined with an enhanced bus interface unit, the microprocessor doubled the performance of the 386 without increasing the clock rate.

4: The development of computer storage devices started with the invention of Floppy disks, by IBM again.If you lo Till the 1950s all computers that were used were vacuum tube based. In the 1960s, transistor based computers replaced vacuum tubes. Transistors made computers smaller and cheaper. They made computers energy-efficient. But transistors led to emission of large amounts of heat from the computer, which could damage them. The use of transistors marked the second generation of computers. Computers of this generation used punched cards for input. They used assembly language. people were amazed at how computers evolved so quikly, you will notice that first generation computers made use of vacuum tubes. These computers were expensive and bulky. They used machine language for computing and could solve just one problem at a time. They did not support multitasking.

5: One of the first computer softwares was called windows by Microsoft.

6: windows is a very popular computer software it has had 8 versions now.heres 7 and 8.and here are some present computers.

7: computers started as these huge build it yourself machines. then they got pretty small and could only do simple one step equations. then they looked like this....... | People wanted the ideal machine and though people thought bigger is better makers stated to make chips ......

8: though windows is very popular it is not the only computer software out there. heres windows mozilla firefox and apple. | Apple is very popular, they supply ipods; ipod nano, shuffle,touch and the iphone which has had 5 generations. | here is a funny picture of the evolution of man.focus on the dude to the far right.

9: now here are some photos of future computers and one computer that looks like its a future one but is already built
