Distinction between a BJT and FET:

BJT	FET
BJT is a bipolar device i.e. the conduction is because of two (bi) carriers - electrons and holes.	FET is a Unipolar device i.e. the conduction is because of either electrons in case of n-channel FET or holes in case of p-channel FET.
BJT is a Current controlled Device. This means that the output current is a function of the input current.	FET is a Voltage Controlled Device. This means that the output current is a function of the input voltage
There are two types: n-p-n and p-np BJT transistors	These are two types: n-channel and p-channel FETs
Comparatively low input impedance	Very high input impedance
Difficult to integrate on Integrated Chips	Easy to integrate on Integrated Chips
