because of high output drive,easy to manufacture and takes less space and also low power consumption...
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
Two, either in NPN or PNP transistors
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
There are many types of transistors, starting out with the typical Base-Collector-Emmitter type. There are two types, starting with the NPN type, The symbol for these is PNP There are also the FET or Field Effect Transistors and their symbols are below, as well as the PNP and NPN. The FET's are divided into the N channel and J channel types:

Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.
No...TIP31 is NPN. The complementary PNP is a TIP32. They are both large high power (40W) devices.
Two, either in NPN or PNP transistors
no, the emitter base junction should be foward for both npn and pnp to act as amplifiers.
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.

pnp answer
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
