✔ 最佳答案
1.Who invented the calculator?

The first calculators were abaci, and were often constructed as a wooden frame with beads sliding on wires. Abacuses were used centuries before the adoption of the written Arabic numerals system and are still used by some merchants, fishermen and clerks in China and elsewhere.

William Oughtred invents the slide rule in 1622

In 1822 Charles Babbage proposed a mechanical calculator, called a difference engine

2.When was the first calculator invented?

it was invented in the 17th century by a frenchman called Blaise Pascal

3. Calculator History:

in the early 1970s, the daily lives of people throughout the developed world were changed profoundly by the advent of a small electronic machine that could per-form basic mathematical problems much more quickly and more accurately than they could be worked out on paper.

電腦是誰發明的,嚴格說起來很難界定。

計算機(computer)的原來意義是“計算器”,也就是說,人類會發明計算機,最初的目的是幫助處理複雜的數字運算。而這種人工計算器的概念,最早可以追溯到十七世紀的法國大思想家帕斯卡。帕斯卡的父親擔任稅務局長,當時的幣制不是十進制,在計算上非常麻煩。帕斯卡為了協助父親,利用齒輪原理,發明了第一台可以執行加減運算計算器。後來,德國數學家萊布尼茲加以改良,發明了可以做乘除運算的計算器。之後雖然在計算器的功能上多所改良與精進,但是,真正的電動計算器,卻必須等到公元1944年才製造出來。

而第一部真正可以稱得上計算機的機器,則誕生於1946年的美國,毛琪利與愛克特發明的,名字叫做ENIAC。這部計算機使用真空管來處理訊號,所以體積龐大(佔滿一個房間)、耗電量高(使用時全鎮的人都知道,因為家家戶戶的電燈都變暗了!),而且記憶容量又非常低(只有100多個字),但是,卻已經是人類科技的一大進展。而我們通常把這種使用真空管的計算機稱為第一代計算機。

第一代的電腦有2間教室大,跟現在我們一般用的個人電腦體積差很多吧。當時的電腦零件是真空管(現在已經找不到了)而存檔的東西是一種打孔卡片,若沒有前人的設計概念,也沒有計算機的發明,所以計算機是誰發明的還有點難界定。
