the vacuum tube
Vacuum tubes are typically evacuated of gases to create a vacuum inside. However, some specialized vacuum tubes may use inert gases like argon or neon to improve performance or provide specific characteristics.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).

who made the vacuum tubes
The transistor replaced the vacuum tube as the primary component in electronic devices, offering smaller size, lower power consumption, and higher reliability. This transition marked the beginning of the semiconductor era in electronics.
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
Vacuum tubes cannot eat. Perhaps you could word your question so as to be more specific for the type of answers desired. The word "something" is very broad and permits many answers.
