With a diode tube you have no control over the current flow and it can only be used as a rectifier, where the triode consist of a control grid, to control the flow of electrons that will reach the anode, this make it possible to use the triode as a amplifier, compared to a transistor the control grid have the same function as the base of the transistor.Advantages?Over tetrodes and pentodes:1. Operation at higher radio frequencies,2. Lower noise figures,3. Simpler circuitry and only one power supply.
Simple diode is a two-terminal pn-junction with appropriate contacts for connecting the junction to external circuits. Power diode is formed by alloying, diffusion, and epitaxial growth. The modern techniques in semiconductor fabrication processes permit the desired device characteristics. The operation of power diodes is similar to that of signal diodes; but it has larger power-, voltage-, and current-handling capabilities than those of ordinary diodes. Switching speed of the power diodes is low compared to that of signal diodes.
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
Hard to answer this one.The triode is a diode with a control electrode (the grid) added.The only useful answer is that a triode is a voltage-controlled doide.Try asking the question so that it can be answered more usefully.

A crystal triode is the old term for transistor. Crystal diodes were well established by the time transistors were invented, so using vacuum tube terminology, the logical name for a diode whose current could be controlled by a third element was "crystal triode".
The zener diode is optimized for reverse breakdown voltage accuracy and stability. This value and its tolerance is specified in more detail than a normal diode.
Actually it can be used as a diode, but rarely is. Just connect the grid and plate together and it has been reduced to a diode. There are also certain circuits that use the cathode and grid as a diode, while also obtaining an amplified output on the plate.
In1883 THOMAS EDISON discover the electron and it,s the begning of electronics after that FLEMING discover the diode and then DE FOREST discover the triode which is called transistor
Sir John Ambrose Fleming patented the thermionic diode in 1904. Then Lee DeForest put a control grid into it to create the triode in 1906.
