  2. Mohamed M. Atalla - Wikipedia

    Mohamed M. Atalla (Arabic: محمد عطاالله; August 4, 1924 – December 30, 2009) was an Egyptian-American engineer, physicist, cryptographer, inventor and entrepreneur. He was a semiconductor pioneer who made important contributions to modern electronics .

  3. Integrated circuit - Wikipedia

    Following Mohamed M. Atalla's proposal of the MOS integrated circuit chip in 1960, the earliest experimental MOS chip to be fabricated was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. The first practical application of MOS SSI chips was for NASA satellites. Medium-scale integration (MSI)

  4. Cách mạng công nghiệp lần thứ ba – Wikipedia tiếng Việtách_mạng_công_nghiệp...

    Vào cuối những năm 1950, kỹ sư của Bell Labs, Mohamed M. Atalla đã chứng minh tính hiệu quả của silic như một vật liệu bán dẫn với quá trình thụ động bề mặt của nó bằng qua sự oxy hóa nhiệt.

  5. Personal identification number - Wikipedia

    Mohamed M. Atalla invented the first PIN-based hardware security module (HSM), dubbed the "Atalla Box," a security system that encrypted PIN and ATM messages and protected offline devices with an un-guessable PIN-generating key.

  6. Memoria flash - Wikipedia, la enciclopedia libre

    El MOSFET (transistor de efecto de campo semiconductor de óxido de metal) original, también conocido como transistor MOS, fue inventado por el ingeniero egipcio Mohamed M. Atalla y el ingeniero coreano Dawon Kahng en Bell Labs en 1959. [3]

  7. ProLiant - Wikipedia

    ProLiant is a brand of server computers that was originally developed and marketed by Compaq and currently marketed by Hewlett Packard Enterprise.After Compaq merged with Hewlett-Packard (HP), HP retired its NetServer brand in favor of the ProLiant brand.

  8. MOSFET - Wikipedia

    Building on this work Mohamed M. Atalla showed that silicon dioxide is very effective in solving the problem of one important class of surface states. Following this Atalla and Dawon Kahng demonstrated a device that had the structure of a modern MOS transistor. The principles behind the device were the same as the ones that were tried by ...

  9. 高錕爵士 ,大紫荊勳賢 ,KBE (英語: Sir Charles Kuen Kao ,1933年11月4日-2018年9月23日),電機工程學家。 於上海市出生及長大(至初中),1949年在逃港潮舉家定居英屬香港,1966年在英國標準電信實驗室做出劃時代的光纤實驗,獲諾貝爾物理學獎表揚「在光傳輸於纤维的光学通信领域突破性成就 ...

  10. Longwave - Wikipedia

    Frequencies from 472–479 kHz are available to licensed amateurs as the new 630 m band, part of the now-defunct maritime band, but this is often considered a medium wave sub-band. Historic [ edit ] Swedish station SAQ, located at the Varberg Radio Station facility in Grimeton, is the last remaining operational Alexanderson alternator long-wave ...

  11. High Speed Packet Access - Wikipedia

    High Speed Packet Access (HSPA) is an amalgamation of two mobile protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols.
