电子计算机又称电脑。世界上第一台电子计算机是在1946年诞生的,至今才只有52年的历史。在此之前,人们制作过许许多多的计算工具,如我国的算盘,17世纪法国的加法机,后来德国人造出的手摇计算机。19世纪,英国人受到法国自动织机的启发,提出了自动计算机的方案,但是限于当时的技术条件,没有能制造成功。20世纪时,电子技术有了很大的发展。1939年,美国哈佛大学开始研制自动数字计算机。直到1943年,这台名叫“马克1号”的机器才开始投入运转,它用3000个称作继电器的电气开关来计数运算,运算速度为每秒三次。在同一个时期,美国一位名叫莫希莱的物理学博士认识到用当时已发明的电子管 Computer, also known as computer. The world’s first electronic computer was born in 1946 and has only 52 years of history. Prior to this, many calculations were made by people, such as the abacus in our country, the French addition machine in the 17th century, and the hand-cranked computer later made by the Germans. The 19th century, inspired by the French automatic loom, the British proposed an automatic computer program, but limited to the technical conditions of the time, did not create success. The 20th century, the electronic technology has made great progress. In 1939, the United States began to develop automatic digital computer Harvard University. It was not until 1943 that the machine named “Mark 1” was put into operation. It counted the operation with 3000 electrical switches called relays at a rate of three times per second. During the same period, a Ph.D. physicist named Mo Xilai in the United States realized that with the electron tube
