Not necessarily. A single pair is not enough. For example
Output = (Input)2 is certainly not linear but input 0 will give output 0.

There are many examples of these. I would compare a linear device as a device giving a linear output as a result of the input. This can be an amplifier or simply the circuits that makes up the amplifier. A non-linear device could be a computer chip or a logic chip that is either on or off (only 2 stages) on both input and output. Some devices combine linear and non linear working modes. A typical OpAmp has got 2 inputs that can vary, where as the output is either On (close to input voltage of the circuit) or Off (close to input negative voltage or GND of the circuit) Other forms of linearities can be within a single transistor. It may have a linear voltage curve. This curve can also be non linear. This most often very dependent upon temperature.
What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.
A function is a relationship between a set of inputs and a set of outputs. The key requirement is that each allowable input relates to exactly one output value. Equations are often used to define a function. That is, the relationship is given by a rule that tells how to find the output from any given input. For example f(x)= 7x-2 says in words, given an input number, say x, multiply it by 7 and subtract 2, to get the associated output. 7x - 2 is called a linear expression because its highest power is one (and a function defined by a linear expression is called a linear function. ) A linear equation is an equation between two linear expressions. Example: 2x + 3 = 7x - 2.
It is the process which converts the input to output.

Output(input), or O(i)
Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.

There is a definite contrast between system input and system output. System input refers to raw data which is fed into the system while system output is processed data which is released by the system.

You how to remember input and output is like a machine do the rest.

A linear electronic device is one where output is linearly proportional, in some way, to input. An example is an amplifier. A non-linear device is one where the input drives the circuit into some kind of saturation mode. An example is a switch, such as is used in TTL IC's.
Both linear ICs and nonlinear ICs has an output voltage which is dependent on the input voltage. However, the difference is that linear ICs produce an output voltage which increases or decreases at a "fixed rate" relative to the input voltage. Nonlinear ICs do not do this. A voltage regulator may be considered nonlinear because as you increase the input voltage the output will climb at the same rate (just like linear ICs), however, once the input voltage reaches a particular level point, the output no longer increases as you increase the input. This is at the point where regulation begins. The nonlinear IC no longer changes its output at a fixed rate relative to the input.
Yes, a certain amount of delay in the input would give rise to an output that equals to delaying the output signal by the same amount directly
