UNIVAC I (Universal Automatic Computer) was the first commercial electronic computer. Sold by Remington Rand Corporation (now Unisys) in 1951. The number of vacuum tubes is 5,200, which is less than one-third compared to ENIAC. The memory is 100 mercury delay tubes. It covers an area of ​​26.7 square meters and weighs 7.2 tons. UNIVAC was developed by the Eckert Mauchly Company established by ENIAC developers John William Mauchly and John Presper Eckert. However, due to financial difficulties, it was acquired by Remington Rand Corporation in 1950, but research and development continued. The first UNIVAC was sold to the U.S. Census Department. An additional 46 units were later sold.

Basic information:

1951: UNIVAC-1 - the first commercial computer system was born, the designers were J.Presper Eckert and John Mauchly. Being used for the census by the U.S. Census Department marked the entry of computers into the era of commercial applications. Since UNIVAC-1 is a computer using transistors, UNIVAC-1 is a representative of the second generation of computers. Computer development is now in its fourth generation.

In 1950, the world’s first computer with stored program function, EDSAC, was designed under the leadership of Dr. von Neumann. Its main feature is that it uses binary and uses mercury delay lines as memory, and instructions and programs can be stored in the computer.

In March 1951, the first general-purpose automatic computer UNIVAC-I designed by Mauchly and Eckert, the main designers of ENIAC, was delivered for use. It can not only perform scientific calculations, but also perform data processing.

UNIVAC-I used a tape drive as external memory for the first time. It first used parity check methods and dual operation circuits to improve the reliability of the system, and was the first to conduct automatic programming experiments.
