The same things a transistor is used for.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
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.
an electron tube containing a near-vacuum that allows the free passage of electric current.
A tube tester is a piece of electronic equipment designed to test the properties of a vacuum tube. The first tube testers were used in World War I to check the tubes in communication equipment.
A klystron, magnetron or travelling-wave tube will generate microwaves. So will a vircator and an inductive output tube. These are just some of the vacuum tubes used to generate microwaves. In a microwave oven, the magnetron, which is a type of cavity resonator, is the device of choice.
the vacuum tube
A needle holder or adapter can be used as a combination system with both a syringe and a vacuum tube. This allows for easy transfer of blood samples between the syringe and the vacuum tube during blood collection procedures.
Red/black
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.
cathode-ray tube
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
Millman's theorem
vacuum tube
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.
who made the vacuum tubes
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.
when the vacuum sucks up things it goes through the tube and into the bag ...Unless you are talking about electronics, then a vacuum tube is used to form an amplifying circuit. Some tubes can emit cathode rays onto a screen (Cathode Ray Tube = CRT) to display a picture and some can function as diodes to regulate current flow.
