Full Form of UNIVAC:
UNIVersal Automatic Computer
UNIVAC Full Form is UNIVersal Automatic Computer. UNIVAC is essentially a range of electronic, digital, stored-program computers beginning with the products from the Eckert-Mauchly Computer Corporation. The name was later applied to a Remington rand company’s division and many of its successor organizations. The Eckert-Mauchly Computer Corporation developed the BINAC, which was essentially the first-ever general-use computer designed for commercial use. However, the successors of the later UNIVAC 1107 remain today as one of the products of Unisys.
With time, UNIVAC generated many separate model ranges. Early versions of UNIVAC 1100 series were basically vacuum tube computers. The UNIVAC I was the original model range and the second commercial computer to be manufactured in the United States of America. Its main memory comprised tanks filled with liquid mercury incorporating delay line memory which was arranged in about 1000 words, each with 12 alphanumeric characters. The first such machine was made in the year 1951. The UNIVAC II was a better version than UNIVAC I, as it incorporated major changes. The changes included non-mercury, magnetic core memory comprising 2000 to 10000 words, circuits which were transistorized, and UNISERVO II tape drives that could make use of either the recent PET film tapes or the previous UNIVAC metal tape.
It showed complete compatibility with extant UNIVAC I programs for data as well as code. In the year 1962, Sperry Rand started shipping UNIVAC III, which was capable of giving support to all UNIVAC I and II formats. This was the last original UNIVAC machines to have been created. UNIVAC has been a registered trademark of Sperry Corporation, Unisys Corporation, Eckert-Mauchly Computer Corporation, Remington Rand Corporation, and Sperry Rand Corporation. Each has come up with some or the other distinct versions of UNIVAC in the market.
