Basically it looks (and is, somewhat) like a stretched out light bulb.
At the front you have the square flatened surface where the picture is displayed, behind it you have a stem, sort of like the stem of a light bulb.
At the end of the stem you have a filament like the one a bulb has and that send electrons towards the front.
Around that glass stem, still at the back, there are some coils which deflect the beam OS electrons to render the picture on the phosphor at the front. Those look like some noodles made of copper wire.

What are computer tubes used for?
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.
Advantages and disadvantages of vacuum tube?
Vacuum tubes have superior sound quality and are typically easy for the user to replace on their own. Disadvantages include their size, rather large for portable devices, and they generally use a larger amount of power then transistors.
When was the 1st amplifier made?
the first amplifier was made in the year 1909. this was the audio amplifier of vacuum tube type.
What does cathode ray tube mean?
A cathode ray tube is what was used in televisions and computer monitors before the advent of the LCD, LED, and Plasma tv screens. They are big, bulky, and very heavy. They are a vacuum tube, with an approximately flat face, on the inner surface of which is deposited a phosphor. When electrons from the cathode asembly reach the phosphor, they cause it to glow at that spot.
Is a vacuum an absence of electricity?
No, a vacuum is an absence of matter.
