Who invented the microprocessor?
449032
In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor. After the invention of integrated circuits revolutionized computer design, the only place to go was down -- in size that is. The Intel 4004 chip took the integrated circuit down one step further by placing all the parts that made a computer think (i.e. central processing unit, memory, input and output controls) on one small chip. Programming intelligence into inanimate objects had now become possible.

In 1976 the cray-1 was developed by Seymour Cray, who left control Data in 1972 to form his own company. This machine was known as much for its horseshoe0shaped design an effort to speed process ing by shortening circuit paths as it was for being the first supercomputer to make vector processing practical. Vector processing, which uses a single instruction to perform the same operation on many numbers, has been a fundamental supercomputer processin style ever since. The Cray-1 could calculate 150 million floating point operations per second. 85 were shipped at a cost of $5 million each. The Cray-1 had a CPU that was mostly constructed of ELC SSI/MSI circuits.

The Pentium is a fifth-generation x86 architecture microprocessor by Intel. First shipped on March 22, 1993, it is the successor to the 486 line. The Pentium was originally to be named 80586 or i586, but due to an ongoing battle with Advanced Micro Devices over the use of the previous processor generations' names--80386 and 80486--and the inability to trademark a number, Intel enlisted the help of Lexicon Branding in order to give their new processor line the Pentium brand. i586 is used in programming reference and parlance though, referring to all the early Pentium processors, and processors that are feature-compatible with the Pentium made by Intel's competitors.

Charles Babbage was the first to conceptualize and design a fully programmable computer as early as 1820, but due to a combination of the limits of the technology of the time, limited finance, and an inability to resist tinkering with his design, the device was never actually constructed in his lifetime. A number of technologies that would later prove useful in computing, such as the punch card and the vacuum tube had appeared by the end of the 19th century, and large-scale automated data processing using punch cards was performed by tabulating machines designed by Hermann Hollerith.

The first *programmable* computer was made in Germany by Konrad Zuse in the late 1930s and early 1940s. They were electromechanical. \nMost of the machines were destroyed by Allied bombings in WW2, so nothing much became of it. The next "big thing" in computers was vacuum tubes.

Charles Babbage, It was his initiative of the differential engine which led to the evolution of computer. For this reason, he's considered the father of computing.

i guess you mean hand-held electronic calculator which uses chip.\n\nTexas, a company, made the first electronic calculator. Jack Kilby, who invented chip (Robert Noyce too is credited to be the inventor of chip), worked in the team which made the first calculator.\n\nThe first calculator did not have the screen but it printed the result on a thermal paper using printer attached to the calculator itself. Don't get the idea of the printer being very large. The first calculator was small enough to be used conveniently.

Microprocessor is a micro processor. \n\nIt processes data, performs calculations and  stores data in a memory. Everything that a computer does is overseen by the CPU and is therefore referred to as the "Brain".\n\nTwo good sites for more information is http://en.wikipedia.org/wiki/Microprocessor\nhttp://computer.howstuffworks.com/microprocessor.htm

The ORACLE or Oak Ridge Automatic Computer and Logical Engine, an early computer built by Oak Ridge National Laboratory, was based on the IAS architecture developed by John von Neumann. As with all computers of its era, it was a one of a kind machine that could not exchange programs with other computers (even other IAS machines). It used vacuum tubes, transistors, and diodes. It used a Williams tube for 2048 words of memory. Its addition time was 70 microseconds, the multiplication time was 370-590 microseconds, and the division time was 590 microseconds. These times include the storage access time, which was about 62 microseconds.

In the March, 1974, issue of QST magazine there appeared the first advertisement for a "personal computer." It was called the Scelbi (SCientific, ELectronic and BIological) and designed by the Scelbi Computer Consulting Company of Milford, Connecticut. Based on Intel's 8008 microprocessor, Scelbi sold for $565 and came with 1K of programmable memory, with an additional 15K of memory available for $2760. The second "personal computer kit" was the Mark-8 (also Intel 8008 based) designed by Jonathan Titus.\n--------------------------\nIn 1977, Radio Shack introduced its TRS-80 microcomputer, also nicknamed the "Trash-80". It was based on the Zilog Z80 processor (an 8-bit microprocessor whose instruction set is a superset of the Intel 8080)\n-----------------------------\nPersonal note... I was among the first users of the TRS-80, using it with my ham radio hobby for generation and decoding Morse code and radio teletype.
