historical evolution of computer

One of the earliest machines of this type was the Chinese abacus. The next major step in the history of computing was the invention of the transistor in 1947. Replacement of the hard-to-implement decimal system (used in Charles Babbage's earlier design) by the simpler binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time. Here’s introducing you to the ancestors of modern computers. His initial idea was to use punch-cards to control a machine that could calculate and print logarithmic tables with huge precision (a specific purpose machine). The original definition of the word \"computer\" was a person who made calculations. In 1671 the German mathematician-philosopher Gottfried Wilhelm von Leibniz designed a calculating machine called the Step Reckoner. In the '60s, computers evolved from professional use to personal use, as the first personal computer was introduced to the public. The market is also filled with other computer models, including the MacBook Pro, iMac, Dell XPS, and iPhones. The computer quickly became known for its Bondi blue, clear casing. It was developed for business use and could address scientific and engineering applications. Self direction control over stop or start, time, pace and place of learning or communication activity. The fifth generation computers are in their development phase. It was, however, capable of up to thousands of operations per second for hours at a time between valve failures. They did not support multitasking. Mechanical calculators, like the base-ten addiator, the comptometer, the Monroe, the Curta and the Addo-X remained in use until the 1970s. Its computations were based on a vacuum tube and it used regenerative capacitor memory. The writing of programmer in machine language is very cumbersome and complicated and this was accomplished by experts only. Computing has evolved with microcomputer architectures, with features added from their larger brethren, now dominant in most market segments. During this time, in the year 1946, the first successful electronic computer called ENIAC was developed and it was the starting point of the current generation of computer. It had an all-transistor design, 13-digit capacity on a 5-inch CRT, and introduced reverse Polish notation (RPN) to the calculator market at a price of $2200. (As of 2005, disk storage costs less than $1 per gigabyte). In the 1970s, a hardware company called IBM (footnote 1) emerged as the computing leader. Lots of efforts are made during last 50 years to obviate the difficulties faced for using the machine language. 3] 1935: Odhner Circa was developed. 8] Around 1890, while others focused on calculating machines, Hermann Hollerith was busy creating punch cards for use with his Tabulating Machine and sorting box. In 1948, the Curta was introduced. It was the plan of a general-purpose programmable computer, employing punch cards for input and a steam engine for power. 15] The desktops were further shrunk as technology progressed further. To 'program' ENIAC, however, meant to rewire it--some say this does not even qualify as programming, otherwise any type of rebuilding some limited computer might be viewed as programming. First of all we will have to understand these terms in true sense. Apple Computers brought out the Macintosh personal computer on January 24 1984. To know about the complete process that how computer works, we will have to come across the various terms such as Data, Processing and Information. The Alto computers were also designed to be kid-friendly so that everyone — no matter the age — could operate a personal computer. If you look at how computers evolved, you will notice that first generation computers made use of vacuum tubes. Modern laptops were the first truly portable computers. But transistors led to emission of large amounts of heat from the computer, which could damage them. The company sold 800,000 computers in the first five months, saving Apple from extinction. Other unique features were a stack architecture, descriptor-based addressing, and no programming directly in assembly language. 7] 1910: Burroughs created an additional machine and called it Adding Machine. As the time passed, the device of more suitable and reliable machine was need which could perform our work more quickly. It used a magnetic core memory of 4000 characters (later expanded to 16,000 characters). Stanford Research Institute brought out ERMA, Electronic Recording Machine Accounting Project, which dealt with automation of the process of bookkeeping in banking. In the daytime, they used to measure time using shadow. In the 1960s, transistor-based computers replaced vacuum tubes. It used 50 24-inch metal disks, with 100 tracks per side. This replaced the fragile and power hungry valves with a much smaller and more reliable component. The Germans also developed a series of teleprinter encryption systems, quite different from Enigma. The latter was designed around punch card input and proved a popular general purpose computer. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. The first computer made for the masses was UNIVAC, made by Remington Rand in 1951.

Over time, during the 1950s and 1960s a variety of different brands of mechanical calculator appeared on the market. The first implemented high-level general purpose programming language, Fortran, was also being developed at IBM for the 704 during 1955 and 1956 and released in early 1957. The first language similar to English was developed in 1950 which was known as Assembly Language or Symbolic Programming Languages. This page has been accessed 724,946 times. Certain characteristics of computer interaction can make computers well suited for distance learning. The above PPT on the progress of computers is available as PDF here. This basic design, which became known as the von Neumann architecture, would serve as the basis for the development of the first really flexible, general-purpose digital computers. @import url(http://www.google.com/cse/api/branding.css); Computing hardware has been an essential component of the process of calculation and data storage since it became useful for numerical values to be processed and shared. Thus a big program of a 3GLs may get replaced by a single statement of a 4GLs. The Colossus used a large number of valves (vacuum tubes). A faster computer brings about faster operation and that in turn causes an economic development. It had about 6,000 vacuum tubes and consumed 25 kW of power. 12] In 1959, IBM 1970 was developed. All the instructions and input data are fed to the computer in numeric form, specifically a binary form. And that language was machine language. But what do you know about its history? Ada Lovelace, Lord Byron's daughter, translated and added notes to the "Sketch of the Analytical Engine" by Federico Luigi, Conte Menabrea. By 1951 the LEO I computer was operational and ran the world's first regular routine office computer job. 10] The first real computer was ENIAC: It could perform arithmetic operations and also be able to perform some general purposes. A more arithmetic-oriented machine is the abacus. Initially in the first generation computer the concept of vacuum tubes was used. The U.S. National Bureau of Standards came up with Standards Electronic/Eastern Automatic Computer (SEAC) in 1950. Analog computers had an advantage over early digital computers in that they could be used to solve complex problems while the earliest attempts at digital computers were quite limited. The first universal programmable computer in continental Europe was created by a team of scientists under direction of Sergei Alekseyevich Lebedev from Kiev Institute of Electrotechnology, Soviet Union (now Ukraine). It was designed by John George Kemeny and Thomas Eugene Kurtz. You use the computer so many times, don’t you? There were three parallel streams of computer development in the World War II era, and two were either largely ignored or were deliberately kept secret. The Z3 was used for aerodynamic calculations but was destroyed in a bombing raid on Berlin in late 1943. Leibniz also described the binary numeral system, a central ingredient of all modern computers.
