How many vocum tubes were in the eniac?
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
Who built the Univac?
Different companies built computers using the Univac trademark over time:Eckert Mauchley Computer Company (EMCC) began building them but ran out of funds before they could deliver any.Remington Rand bought EMCC in 1950 just before EMCC went bankrupt and finished and sold them initially.Sperry Rand after Sperry Corporation and Remington Rand merged in 1955.Sperry Univac after Sperry Rand changed its name in 1978 when they decided to specialize in computers and sold unrelated divisions.Unisys after Sperry Univac and Burroughs Corporation merged in 1986.
How does eniac work as there was no software?
ENIAC (Electronic Numerical Integrator and Computer) operated using a series of vacuum tubes and was programmed through manual wiring and the configuration of plugboards. It performed calculations by executing a sequence of arithmetic operations, which were specified by physical connections rather than software. Operators would set up the machine for each task by rewiring it according to the desired program, making ENIAC one of the first programmable computers, albeit without modern software. Its design laid the groundwork for future developments in programmable computing.
What were the sizes of first generation computers?
It depends on how you define 1st generation. The earliest computers were mechanical, and the size of a fairly large room. We then had electrical computers, like the Enigma encryption device, about the size of a large typewriter. 1st generation electronic devices were quite big - about 4 filing cabinets, with the first generation of 'home' computers being about the size we have now, but using CRT monitors.
What was the first fully functional computer called?
ENIAC. No it was not the ENIAC. The first fully functional, fully programmable computer was the Z3. It was invented by a German Konrad Zuse before the ENIAC existed. Americans did not invent the computer.
What is the difference of eniac between univac?
total memory of ENIAC was 20 words all in accumulators; total memory of UNIVAC was 1000 words main memory, 120 words of I/O buffer, and a 10 word "Y" register all in mercury delay lines.words on ENIAC were 10 decimal digits long; words on UNIVAC were 12 alphanumeric characters long.digits on ENIAC were stored in 10 flip-flop ring counters; digits on UNIVAC were stored in 6 flip-flop characters.arithmetic on ENIAC was done by counting pulses sent from one accumulator to another; arithmetic on UNIVAC was done by logic circuits in the single accumulator.programming ENIAC was done by manually interconnecting the various accumulators and special purpose units with cables and individual wires to effectively create a new machine for each problem; programming UNIVAC was done by loading its memory from a magnetic tape containing the previously coded program, these tapes were written by programmers using UNIVAC to help them as is still done with modern computers today.I/O on ENIAC was all done with punchcards; I/O on UNIVAC was all done with magnetic tape.etc.
What were the first computers like?
The first computers, developed in the mid-20th century, were large, room-sized machines that used vacuum tubes for circuitry and magnetic drums for memory. They operated on binary code and required complex programming, often using punched cards or paper tape for input. These early systems, like the ENIAC and UNIVAC, were primarily used for scientific calculations and data processing, lacking the user-friendly interfaces we have today. Their immense size and power consumption limited their accessibility and use, making them primarily tools for government and research institutions.

When was the computer's keyboard introduced?
The first US commercial general-purpose programable electronic digital computer UNIVAC I, introduced in 1951 by Remington Rand had a keyboard on its operator console. Earlier computers may also have had keyboards, it is hard to track down specifics on all the early "one off" machines. ENIAC (1946) and the ABC (1942) had no keyboard; however data entry for both machines was done using IBM 016 Keypunches, which did have keyboards.
What is the memory capacity of eniac?
The ENIAC (Electronic Numerical Integrator and Computer), one of the earliest electronic general-purpose computers, had a memory capacity of about 20 decimal digits. This was implemented using vacuum tube-based memory and was quite limited compared to modern standards. ENIAC primarily used punch cards for input and output, relying on its arithmetic unit to perform calculations rather than storing large amounts of data.

Who made the third computer and how?
The third computer is often considered to be the Electronic Numerical Integrator and Computer (ENIAC), developed by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. Completed in 1945, ENIAC was a massive, vacuum tube-based machine designed for general-purpose calculations. It was programmed using a series of plugboards and switches, making it significantly more flexible than its predecessors, which were typically designed for specific tasks. ENIAC's development marked a major milestone in computing history, paving the way for future advancements in electronic computers.
Which year to the military start using computers to make wartime calculations?
The military began using computers for wartime calculations during World War II, with significant developments occurring in the early 1940s. One of the earliest examples was the use of the Electronic Numerical Integrator and Computer (ENIAC) in 1945, which was employed for ballistic calculations. This marked a pivotal shift in military operations, allowing for more complex and rapid computations than traditional methods.
What was the first fully functional computer called?
ENIAC. No it was not the ENIAC. The first fully functional, fully programmable computer was the Z3. It was invented by a German Konrad Zuse before the ENIAC existed. Americans did not invent the computer.
What is a good sentence using the word institutions?
The public institutions are becoming very long.
