Slide Rule: Slayd qoidasi:In 1620, William Oughtred invented the slide rule, which is a calculating device, and uses principles of log tables.1620-yilda Uilyam Outred qurilmalar hisobi bilan shug’ullanuvchi slayd qoidani taklif qildi va u logarifm jadvali qoidalarida ishlatiladi.Pascal’s adding machine:Paskalning qo’shimcha mashinasi: In 1642, Blasé Pascal, a French mathematician invented the first mechanical calculator. 1642-yilda Fransiyalik matematik Bleyz Paskalb 1-mexanik kalkulyatorni taklif qildi.This made use of a number of wheels to perform the operations. Bu mexanizmlar sonidagi operatsiyalarda ishlatiladi.Multiplication was performed by a number of additions and subtractions.Punched cards: between 1802 and 1804 Joseph Jacquard invented punched cards. 1802-1804-yiullarning orasida Jozef Jakuard komposter kartochkalarini taklif etadi.This was originally invented to improve the production of woven cloth. Bu to’qilgan kiyimlarni rivojlantirishni taklif qilgan.The main feature of Jacquard, loom was a series of punched, cards strung tightly side in a long strip. Jakuardning o’ziga xos xususiyatlaridan biri to’qish stanogi tamg’a qiladi.The cards were automatically fed to control looms weaving action.Kartochkalar avtomatik ravishda to’qish jarayonidagi stanogni nazorat qiladi. Then, each wrap would be raised or not according to the rule:Keyin har bir ro’mol ko’payadi yoki qoidaga bo’ysunadi:Hole in the card- wrap thread not raised Kartochkada teshik bo’lsa,ro’mol ko’paymaydi.No hole in the card- wrap thread raised.Kartochkada teshik bo’lmasa,ro’mol ko’payadi.This further led to the development of the binary system.Bu keyin qo’sh sistemanin g rivojlanishiga olib keladi. Binary means 2 numbered.Qo’sh sistemaning ma’nosi 2 raqamlangan.Francis Bacon in 1623 made use of binary codes for number representation.Frankis Beykon 1623-yilda Ikkilangan sanoq sistemani ishlatadi.Babbage’s Difference Engine: Charles Babbage, an English Mathematician in 1822 brought a new break Von through in the development of calculating machines. Ingliz matematigi Charlz Bebbej 1822-yilda hisoblash mashinalarini rivojlantirish uchun yangi teshik olib keldi.He introduced a new concept called «Level Difference» which was used largely in future computers. U “Darajalar turli xil”nomi bilan ataladigan yangi g’oyani tanishtirdi,u kelajakdagi kompyuterlar uchun ishkatilgan.He is also rightly called «Father of Modern Computers».U yana “Zamonaviy kompyuterlarning otasi ”ham deb ataladi.Download 259.5 Kb.
