The Full Form of UNIVAC Meaning, and Definition 

On this page, We are going to learn about the full form of UNIVAC and the meaning of UNIVAC, As well as the meaning, definition, and acronym for UNIVAC in different categories. So you should read this post till the end.

Full Form of UNIVAC: Universal Non-Integrated Vacuum Actuated Computer

UNIVAC Stands for Universal Non-Integrated Vacuum Actuated Computer. Univac was a first-generation computer system that includes hardware and software components. It is a self-contained, digital system, in which a user performs all computations. The user has direct access to the system and can add programs to it.

Characteristics of UNIVAC Computer

It was 25 feet long and 50 feet wide, with 5,600 tubes, 18,000 crystal diodes, and 300 relays. The device used serial circuitry had a 2.25 MHz bit rate and could store 1,000 words or 12,000 characters internally.

There were many inputs and outputs with UNIVAC, which was used for general-purpose computing.

There was an estimated 120 kva of power consumption. It has an arithmetic speed of 0.525 milliseconds, a multiplication speed of 2.15 milliseconds, and a division speed of 3.9 milliseconds.

Additionally, UNIVAC I was the first computer to use buffer memory and a magnetic tape drive. The Univac I is equipped with ten magnetic tape drives, all of which are compatible, meaning tapes created on one drive can be read by another.

Due to the buffering on magnetic tapes, input and output operations could be performed independently of other central processing tasks, greatly increasing efficiency.

Features of UNIVAC

  • 5000 vacuum tubes were used in UNIVAC.
  • Its weight was 9 tons.
  • It used to consume a lot of electricity, about 125KW.
  • Its size was huge and it took up 35 square meters of space.
  • In this, a tape driver was used for input.
  • It worked at that time at 2.25 megahertz clock speed.
  • Up to 1000 words could be stored in its main memory.

What was UNIVAC used for?

A Univac I was uniquely suited to processing large amounts of data. In UNIVAC, all errors could be detected immediately due to duplicate arithmetic units.

For sorting and processing large data files on these computers, Census Bureau employees created many pioneering software programs.

It was intended to replace the punch-card accounting machines of the time with a commercial data-processing computer.

The machine was capable of reading 7,200 decimal digits per second, making it the fastest commercial machine ever built.
