Magnetic tape was first used to record computer data in 1951 on the Eckert-Mauchly UNIVAC I.

* 1951 – Remington Rand delivers the first UNIVAC I computer to the United States Census Bureau.

Programmers of early 1950s computers, notably UNIVAC I and IBM 701, used machine language programs, that is, the first generation language ( 1GL ).

Norwegian Computing Center got a UNIVAC 1107 August 1963 at a considerable discount, on which Dahl implemented the SIMULA I under contract with UNIVAC.

SIMULA I was fully operational on the UNIVAC 1107 by January 1965.

After the war, development continued with tube-based computers including, military computers ENIAC and Whirlwind, the Ferranti Mark 1 ( the first commercially available electronic computer ), and UNIVAC I, also available commercially.

* March 31 – Remington Rand delivers the first UNIVAC I computer to the United States Census Bureau.

March 31: UNIVAC I.

* June 14 – UNIVAC I is dedicated by the U. S. Census Bureau.

A UNIVAC I computer was accepted by the Bureau in 1951.

The A-0 system ( Arithmetic Language version 0 ), written by Grace Hopper in 1951 and 1952 for the UNIVAC I, was the first compiler ever developed for an electronic computer.

The UNIVAC I was finished on December 21, 1950.

John William Mauchly ( August 30, 1907 – January 8, 1980 ) was an American physicist who, along with J. Presper Eckert, designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.

It was a pseudocode interpreter for mathematical problems proposed in 1949 and ran on the UNIVAC I and II.

It was developed for the UNIVAC I at Remington Rand under Grace Hopper.

The UNIVAC I ( UNIVersal Automatic Computer I ) was the first commercial computer produced in the United States.

In the years before successor models of the UNIVAC I appeared, the machine was simply known as " the UNIVAC ".

As well as being the first American commercial computer, the UNIVAC I was the first American computer designed at the outset for business and administrative use ( i. e., for the fast execution of large numbers of relatively simple arithmetic and data transport operations, as opposed to the complex numerical calculations required by scientific computers ).

However, the early market share of the UNIVAC I was lower than the Remington Rand Company wished.

To promote sales, the company joined with CBS to have UNIVAC I predict the result of the 1952 Presidential election.

In the mid-1960s MAD was ported at the University of Maryland to the UNIVAC 1108.

The A-2 system was developed at the UNIVAC division of Remington Rand in 1953 and released to customers by the end of that year.

The UNIVAC Solid State was a 2-address, decimal computer, with memory on a rotating drum with 5000 signed 10 digit words, aimed at the general purpose business market.

A complete UNIVAC 1105 computer system required 160 kW of power ( 175 KVA, 0. 9 power factor ) and an air conditioning unit with a power of at least 35 tons ( 123 kW ) for cooling input water.

SUMITS, a UNIVAC 1110 mainframe was installed at the MECC facility at 1925 Sather, address later changed to 2520 Broadway Drive ), next to Highway 280.

The UNIVAC LARC ( Livermore Advanced Research Computer ) was Remington Rand's first attempt at building a supercomputer.

The original intention of AMC was that all programming for AMC systems worldwide would be written in AIMACO and compiled on a UNIVAC in AMC headquarters at Wright-Patterson Air Force Base in Dayton, Ohio.

He challenged the accusations, but it took two years before a hearing allowed him to work at his company again ; by then the UNIVAC was seriously behind schedule.

The programming to allow the UNIVAC I to be used in predicting the outcome of the 1952 Presidential election had to be done by Mauchly and University of Pennsylvania statistician Max Woodbury at Mauchly's home in Ambler, Pennsylvania.

However, upon acceptance at the company premises, truck load after truck load of punched cards arrived to be recorded on tape ( by what was called jokingly the card to pulp converters ) for processing by UNIVAC.

In 1976, the Department of Commerce presented her with a further Certificate of Appreciation on the 25th Anniversary of UNIVAC I, and then at the 1981 Computer Conference cited her a third time as a " UNIVAC I pioneer.

The UNIVAC English Language compiler was the first one produced at MetLife, in 1959.

The Electronic Control Company soon became the Eckert – Mauchly Computer Corporation and it received an order from the National Bureau of Standards to build the Universal Automatic Computer ( UNIVAC ).

Every time I closed my eyes, I saw Gray Eyes rushing at me with a knife.

Next to him was a young boy I was sure had sat near me at one of the trading sessions.

I was nearly thirty at the time.

I would turn away from my writing in the hope of getting a good look at them but I never quite succeeded.

They, and the two large fans which I could dimly see as daylight filtered through their vents, down at the far end of the hall, could be turned on by a master switch situated inside the office.

By counting the number of stalls and urinals I attempted to form a loose estimate of how many men the hall would hold at one time.

I could observe the two fans down at the end, but their size in themselves meant nothing to me as long as I had no measure of comparison.

No sooner would I turn my head away from the counter before he would address me, at times quite sharply, in order to bring back my attention.

I felt strongly attached to the hall, however, and hardly a day passed when I did not go to look at it from a distance.

My future lay solely with the hall, yet what did I know about the hall at this point??

I was at once disappointed, although just what I had expected him to look like I could not have explained.

What sort of men I would come into contact with, at the hall??

This desire, I went on, growing voluble as my conviction was aroused, had mounted at such a rate recently that I now found its realization necessary not only to my physical but also to my spiritual wellbeing.

I would have foregone my romantic chances rather than leave a friend sweltering and dusty and -- Well, at least I wouldn't have shouted back a taunt.

I was again in motion and at a speed which belied the truck's similarity to Senor X's Ford turtle.

At once my ears were drowned by a flow of what I took to be Spanish, but -- the driver's white teeth flashing at me, the road wildly veering beyond his glistening hair, beyond his gesticulating bottle -- it could have been the purest Oxford English I was half hearing ; ;
