Its a Non Linear Device.Its just an electronic switch which turns on during forward bias and off during reverese bias.That is, it gets shorted with minimum resistance and opened with infinite resistance during forward and reverse biases respectively. More over any linear device has to obey superposition therem and homogenity. A linear device is that whose output is directly propostional to input. In case of diode, output (i.e current) is not directly propostional to it input(i.e voltage across it).From it governing equation I=I' * e^(V/V') ,where I' and V' is constant ,it is absolutly clear.
Linear elements :In an electric circuit, a linear element is an electrical element with a linear relationship between current andvoltage. Resistors are the most common example of a linear element; other examples include capacitors,inductors, and transformers.Nonlinear Elements :A nonlinear element is one which does not have a linear input/output relation. In a diode, for example, the current is a non-linear function of the voltage.Most semiconductor devices have non-linear characteristics.

diode is nonlinear device,so device from diode is also nonlinear
since the diode shows its characteristics in a non linearly it is called as nonlinear element since the transistor shows its characteristics in a linear way it s called as linear element Transistors are typically operated in their linear region (such as when used in amplifier circuits), or as switches (where you will in general ignore the nonlinearity of the transistor). Transistors are typically DC biased to operate in this linear region. Diodes are not biased in this way. Strictly speaking, both are nonlinear devices, although transistors can be used in their linear operation region, while diodes are not.
Because Thevenin does not work for a nonlinear network, e.g. a battery in series with a diode and resistor.
A nonlinear component is one in which the current is not proportional to the voltage, in other words it does not follow Ohm's law. The commonest nonlinear component is a diode. A nonlinear circuit is one with a nonlinear component in it.

Yes, the rate of change can be linear or non-linear.
It is linear.
This is non-linear
