Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.
First generation computers.

I'm not sure what you mean by "this computer" but vacuum tubes have the following problems anywhere they are used:high voltage required for operationget very hotshort lifetime, heater burns outlarge physical size

FIRST GENERATION
first generation
The same time as the early computers. They were large because their components (vacuum tubes) were large, not because they could handle large problems.
They are first generation computers because they used vacuum tubes as active elements, as did almost all computers until 1958 when the first generation is usually considered to have ended. From 1958 on most computers used discrete transistors as active elements until 1964.Note: ABC & ENIAC are both very early first generation computers as they used ordinary Radio receiver vacuum tubes, not the more expensive Computervacuum tubes that were introduced about 1948 to 1949. The later Computer vacuum tubes were custom redesigned versions and were far more reliable than ordinary Radio vacuum tubes had been.
By most definitions, first generation computers were the ones built with vacuum tubes.
