Namun, untuk mendapatkankan hasil pengolahan data dengan secepat dan seakurat mungkin, manusia berusaha untuk membuat alat-alat mekanik maupun elektronik yang bisa membantu mereka dalam penghitungan dan pengolahan data. Proses dan usaha yang panjang itulah yang menyebabkan adanya komputer yang ada pada saat ini. Proses inipun masih terus berlanjut dan memungkinkan terciptanya komputer yang jauh lebih canggih di masa datang. Saat ini komputer dan piranti pendukungnya telah masuk dalam setiap aspek kehidupan dan pekerjaan. Komputer yang ada sekarang memiliki kemampuan yang lebih dari sekedar perhitungan matematik biasa. Di antaranya adalah sistem komputer di kassa supermarket yang mampu membaca kode barang belanja, sentral telepon yang menangani jutaan panggilan dan komunikasi, jaringan komputer dan internet yang menghubungkan berbagai tempat di dunia. 1 Ide penciptaan komputer bermula dari keinginan manusia untuk menciptakan alat bantu menghitung (komputasi). Komputer canggih yang kita temui saat ini adalah suatu evolusi panjang dari penemuan-penemuan manusia sejak dahulu kala yang awalnya berupa alat mekanik maupun elektronik yang berkembang secara bertahap. Sejarah perkembangan komputer dibagi menjadi beberapa periode/ generasi: Generasi Alat Hitung Tradisional dan Kalkulator Mekanik Komputer Generasi Pertama Komputer Generasi Kedua Komputer Generasi Ketiga Komputer Generasi Keempat Komputer Generasi Kelima 1.2 Generasi Alat Hitung Tradisional dan Kalkulator Mekanik Sekitar 5000 tahun yang lalu di Asia kecil dan masih digunakan di beberapa tempat hingga saat ini, dapat dianggap sebagai awal mula alat komputasi. Alat ini memungkinkan penggunanya untuk melakukan perhitungan menggunakan biji- bijian geser yang diatur pada sebuah rak. Para pedagang di masa itu menggunakan sempoa untuk menghitung transaksi perdagangan. Seiring dengan munculnya pensil dan kertas, terutama di Eropa, abacus kehilangan popularitasnya. 2 Gambar 1.1 Alat Hitung Sempoa atau Abacus Pada tahun 1642, Blaise Pascal (1623-1662), yang pada waktu itu berumur 18 tahun, menemukan apa yang disebut sebagai kalkulator roda numerik (numerical wheel calculator) untuk membantu ayahnya melakukan perhitungan pajak. Kotak persegi kuningan ini yang dinamakan Pascaline, menggunakan delapan roda putar bergerigi untuk menjumlahkan bilangan hingga delapan digit. Alat ini merupakan alat penghitung bilangan berbasis sepuluh. Kelemahan alat ini adalah hanya terbatas untuk melakukan penjumlahan. Gambar 1.2 Alat Hitung Pascaline Tahun 1694, seorang matematikawan dan filsuf Jerman, Gottfred Wilhem von Leibniz (1646-1716) memperbaiki Pascaline dengan membuat mesin yang dapat mengalikan. Sama 3 seperti pendahulunya, alat mekanik ini bekerja dengan menggunakan roda-roda gerigi. Dengan mempelajari catatan dan gambar-gambar yang dibuat oleh Pascal, Leibniz dapat menyempurnakan alatnya. Pada tahun 1820, kalkulator mekanik mulai populer. Charles Xavier Thomas de Colmar menemukan mesin yang dapat melakukan empat fungsi aritmatik dasar. Kalkulator mekanik Colmar “arithometer” mempresentasikan pendekatan yang lebih praktis dalam kalkulasi karena alat tersebut dapat melakukan penjumlahan, pengurangan, perkalian dan pembagian. Dengan kemampuannya, arithometer banyak dipergunakan hingga masa Perang Dunia I. Bersama-sama dengan Pascal dan Leibniz, Colmar membantu membangun era komputasi mekanikal. Awal mula komputer yang sebenarnya dibentuk oleh seorang profesor matematika Inggris, Charles Babbage (1791- 1871). Tahun 1812, Babbage memperhatikan kesesuaian alam antara mesin mekanik dan matematika yaitu mesin mekanik sangat baik dalam mengerjakan tugas yang sama berulangkali tanpa kesalahan; sedang matematika membutuhkan repetisi sederhana dari suatu langkah-langkah tertenu. Masalah tersebut kemudain berkembang hingga menempatkan mesin mekanik sebagai alat untuk menjawab kebutuhan mekanik.

  • Trends in Electrical Efficiency in Computer Performance
    ASSESSING TRENDS IN THE ELECTRICAL EFFICIENCY OF COMPUTATION OVER TIME Jonathan G. Koomey*, Stephen Berard†, Marla Sanchez††, Henry Wong** * Lawrence Berkeley National Laboratory and Stanford University †Microsoft Corporation ††Lawrence Berkeley National Laboratory **Intel Corporation Contact: JGKoomey@stanford.edu, http://www.koomey.com Final report to Microsoft Corporation and Intel Corporation Submitted to IEEE Annals of the History of Computing: August 5, 2009 Released on the web: August 17, 2009 EXECUTIVE SUMMARY Information technology (IT) has captured the popular imagination, in part because of the tangible benefits IT brings, but also because the underlying technological trends proceed at easily measurable, remarkably predictable, and unusually rapid rates. The number of transistors on a chip has doubled more or less every two years for decades, a trend that is popularly (but often imprecisely) encapsulated as “Moore’s law”. This article explores the relationship between the performance of computers and the electricity needed to deliver that performance. As shown in Figure ES-1, computations per kWh grew about as fast as performance for desktop computers starting in 1981, doubling every 1.5 years, a pace of change in computational efficiency comparable to that from 1946 to the present. Computations per kWh grew even more rapidly during the vacuum tube computing era and during the transition from tubes to transistors but more slowly during the era of discrete transistors. As expected, the transition from tubes to transistors shows a large jump in computations per kWh. In 1985, the physicist Richard Feynman identified a factor of one hundred billion (1011) possible theoretical improvement in the electricity used per computation.

  • Sperry Rand's Third-Generation Computers 1964–1980
    Sperry Rand’s Third-Generation Computers 1964–1980 George T. Gray and Ronald Q. Smith The change from transistors to integrated circuits in the mid-1960s marked the beginning of third-generation computers. A late entrant (1962) in the general-purpose, transistor computer market, Sperry Rand Corporation moved quickly to produce computers using ICs. The Univac 1108’s success (1965) reversed the company’s declining fortunes in the large-scale arena, while the 9000 series upheld its market share in smaller computers. Sperry Rand failed to develop a successful minicomputer and, faced with IBM’s dominant market position by the end of the 1970s, struggled to maintain its position in the computer industry. A latecomer to the general-purpose, transistor would be suitable for all types of processing. computer market, Sperry Rand first shipped its With its top management having accepted the large-scale Univac 1107 and Univac III comput- recommendation, IBM began work on the ers to customers in the second half of 1962, System/360, so named because of the intention more than two years later than such key com- to cover the full range of computing tasks. petitors as IBM and Control Data.

  • Annotations of First Generation Systems Development in Sweden
    Annotations of First Generation Systems Development in Sweden Janis Bubenko, Jr. Department of Computer and Systems Science, Royal Institute of Technology and Stockholm University, Forum 100, SE-16440, Kista, Sweden, janis@dsv.su.se Abstract: This work presents episodes of first generation information systems development in Sweden using two particular computers, ALWAC IIIE, during the period 1957–1961, and Univac III during 1963–1964. The ALWAC IIIE at ADB Institute, Gothenburg, was used for technical as well as for administrative applications. Another episode concerns re- engineering of an inventory management application; it used the ALWAC IIIE for the Swedish Defence Material Administration in 1960. The next episode concerns the computer Univac III. A sales contract between Götaverken AB and Univac included a guarantee by Univac to transfer one of Götaverken’s punched card routines to a magnetic tape oriented routine on Univac III. The development work was carried out on a Univac III at Kantonalbank in Bern, Switzerland. They did the work in night shifts during a period of five months. Only one Univac III was installed in Sweden. Keywords: First generation, information system development, Alwac IIIE, Univac III, Gothenburg 1. Introduction Information systems development is today a complex activity encompassing many types of activities and involving different kinds of stakeholders. It uses many different methods, techniques, and supporting tools. The development process deals with issues of many kinds such as organisational, economic, administrative, technical, social, as well as political. During the 1950-1960 decade, called the first generation of systems development, the development process was much simpler. In the 1950s, heavy emphasis was on primarily two types of activities: programming and testing.

Richard H. Gumpertz i Error I)ctection with Memory Tags Abstract The ability to achieve and maintain system reliability is an important problem that has become more critical as the use of computers has become more common. Fundamental to improved reliability is the ability to detect errors promptly, before their effects can be propagated. This dissertation proposes methods for using storage tags to detect a broad class of hardware and software errors that might otherwise go undetected. Moreover, the suggested schemes require minimal extensions to the hardware of typical computers. In fact, it is shown that in many situations tags can be added to words of storage without using any extra bits at all.
