Generally, they were called Vacuum Tubes.
There were many different kinds and models, such as the Selectron, and Williams Tube. Their purpose was to store data by using a complex electro-magnetic electron transferral process. This allowed them to store very small amounts of data per tube. Since they were electrically driven, cutting the power on them would cause data loss- the computer had to be on 24/7. Later developments of the technology solved this problem.
There were also non-tube based memories such as UNIVAC's Mercury Delay Line Memory, Piezoelectric crystal memory, magnetorestrictive coils, bubble memory, drum memory, twistor memory, and the most popular Core memory, or Magnetic Core memory.

What is the first prototype computer?
The prototype for the Atanasoff-Berry computer was demonstrated in October 1939, it used 11 vacuum tubes. The full Atanasoff-Berry computer (the first electronic digital computer) was finished in early 1942, it used 280 vacuum tubes, 31 thyratrons, and was about the size of a desk.
How many vacuum tubes in first generation computer?
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
Why the first-generation of computer use vacuum tubes?
The first digital computer that used vacuum tubes was the ABC, completed in 1942 by Dr. John Vincent Atanasoff and Clifford Berry in Ames, IA.An early analog computer that used vacuum tubes was the Differential Analyzer, completed in 1929 by Vannevar Bush and a large team at MIT. (there probably were other smaller analog computers of this type that used vacuum tubes before this, so it probably isn't the first but its the earliest where I can find it clearly documented).
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.
How do the computers of 1940 and 1950 compare to modern computers?
There was only one electronic computer in World War Two, which was called ENIAC, and was a building full of vacuum tubes. It was built to calculate artillery projectile paths, and had to have the program wired in. It had no memory, and displayed the output with glowing lights.

What is pair of tubes with fingerlike projections that draw in the egg called?
The tubes are called as fallopian tubes.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
What are two tubes connected to the uterus called?
They are called Fallopian tubes
What are test tubes called?
A group of test tubes are called samples.
When the large computer invented?
The same time as the early computers. They were large because their components (vacuum tubes) were large, not because they could handle large problems.

What are the tubes called inside the kidneys?
The tubes from the kidneys to the bladder are called ureters.

What are the bundles of tubes called?
A bundle of test tubes are specifically called samples when put into groups.
Was the computer built by vacuum tubes?
yes it was yes it was
