Here you can see Computer are those which take input and after processing the input it produce some output.
But why the word "ELECTRONIC DEVICE" came into the picture ?
Because only Electronic Device are capable to process some input and produce some output.
Here some people are says,then Fan is also a COMPUTER !
Fan is not a Computer because this is an ELECTRICAL Device.
Electronic Device V/S Electrical Device
* Electrical devices take the energy of electrical
current, the flow of electrons in a conductor, and transform it in simple ways
into some other form of energy—most likely light, heat, or motion.
* An electric
device is one that directly uses electrical energy to perform a task.
* If
something uses
electricity merely as energy, it is electrical.
* If it uses electricity as the medium for manipulating
information, it is almost surely electronic.

| Electronics VS Electrical |
* In short, all electronic devices are
also electrical devices, but all electrical devices are not electronic devices.
At the end we know that what is exact computer , and what is not.
When someone questioning you that 'What is standard Computer ?', then you will says Laptop, Computer are the standard Computer.
To understanding what is the input, output and how it processing the input you can follow the images......

Notes: In the past many people used computer to do some calculating work, they used computer as calculating machine. But now all are depends on computer so Application of computer are huge.
** Computer are act like human because of the "evolution of computer", Now there is only one difference between human and the computer is "How we process input". Humans are common sense but other-hand Computer have no common sense(they have some prerecorded functionality for perform such a task).
Example of Computer:
As you can see that there is an watch, thermometer, car speedometer, micro-oven all are the example of computers, because all are capable to *manipulate information, *electronic device, *take input, *process inputs *give output.
