Like other computing pioneers before them, Eckert and Mauchly formed a company in 1947 to develop a commercial computer. The company was called the Eckert-Mauchly Computer Corporation. Their objective was to design and build the Universal Automatic Computer or UNIVAC. Because of difficulties of getting financial support, they had to sell the company to Remington Rand in 1950. Eckert and Mauchly continued to work on the UNIVAC at Remington Rand and completed it in 1951.Known as the UNIVAC I,this machine was the first commercially available computer.像他们之前的其他计算机先驱一样,Eckert和Mauchly在1947年组成了一家公司开发商业计算机。公司名叫Eckert-Mauchly计算机公司。他们的目标是设计并建造通用自动计算机或UNIVAC。因为难以获得财政支持，他们不得不在1950年把公司卖给了Remington Rand公司。Eckert和Mauchly继续在Remington Rand公司从事UNIVAC的研制工作，并在1951年取得成功。众所周知的UNIVACI机器是世界上第一部商业化计算机。
The first UNIVAC I was delivered to the Census Bureau and used for the 1950 census.The second UNIVAC I was used to predict that Dwight Eisenhower would win the 1952 presidential election, less than an hour after the polls closed.The UNIVAC I began the modern of computer use.第一台UNIVAC I被交付人口普查局用于1950年的人口普查。在投票点关闭后1小时之内，第二台 UNIVAC I被用于预测D.艾森豪威尔会赢得1952年总统大选。UNIVAC I开始了现代计算机的应用。
First-generation computers were characterized by the use of vacuum tubes as their principal electronic component. Vacuum tubes are bulky and produce a lot of heat,so first-generation computers were large and required extensive air conditioning to keep them cool. In addition, because vacuum tubes do not operate very fast, these computers were relatively slow.第一代计算机的特色是使用真空管为其主要电子器件。真空管体积大且发热严重,因此第一代计算机体积庞大，并且需要大量的空调设备保持冷却。此外,因为真空管运行不是很快，这些计算机运行速度相对较慢。
The UNIVAC I was the first commercial computer in this generation. As noted earlier, it was used in the Census Bureau in 1951. It was also the first computer to be used in a business application. In 1954, General Electric took delivery of a UNIVAC I and used it for some of its business data processing.UNIVAC 是第一代中最早的商业化计算机。如前所述，它在1951年被用于人口普查局。它还是第一部用于商业应用的计算机。在1954年,通用电气接收了UNIVAC ，并用它进行一些商业数据处理。
The UNIVAC I was not the most popular first-generation computer,however. This honor goes to the IBM 650.It was first delivered in 1955 before Remington Rand could come out with a successor to the UNIVAC I.With the IBM 650, IBM captured the majority of the computer market, a position it still holds today.然而,UNIVAC I并不是最流行的第一代计算机。这一荣誉属于IBM650。它在Remington Rand能够造出UNIVAC I的后续产品之前的1955年首次交付使用。凭借IBM650,IBM占有了大半计算机市场，它在今天仍然保持这一位置。
At the same time that hardware was evolving,software was developing. The first computers were programmed in machine language, but during the first computer generation, the idea of programming language translation and high-level languages occurred.Much of the credit for these ideas goes to Grace Hopper,who,as a Navy lieutenant in 1945,learned to program the Harvard Mark I.In 1952,she developed the first programming language translator, followed by others in later years. She also developed a language called Flow-matic in 1957,which formed the basis for COBOL, the most commonly used business programming language today.同时，硬件在进化,软件也在发展。第一部计算机用机器语言编程，但是在第一代计算机期间，程序语言翻译的概念和高级语言出现了。这些主意大部分归功于Grace Hopper,她在1954年是一名海军上尉，学习为哈佛Mark I计算机编程。在1952年，她开发了第一种编程语言翻译器,在稍后的数年内为其他人所效仿。她还在1957年开发了一种称为Flow-matic的语言,为COBOL——今天最广泛应用的商业编程语言——奠定了基础。
