Comparison between functional and nin-functional requirements can be as follows:

The requirements which a normal user can be specify with some techincal knowledge are the funtional requirements whereas the requirements which are specified only by the people who are technical are the non-functional requirements. For example: Non functional requirements by technical people like software developers whereas functional requirements by users like application users.
The functionality of software can be tested with the help of functional requirements whereas the performance of the software can be tested with the help of non-functional requirements. For example: Testing the API in the software is functional requirement as functionality of software depends upon the API whereas testing the security of the software in non-functional requirement.

Fundamentals proposed in Krutchen's 4+1 model:

The processes of the system which interacts with other processes is described by the process view whereas the way the software is distributed in the hardware of the system on which the software is running is described by the physical view whereas all the abstractions which are performed on the keys which are used in the system is desribed by the logical view whereas the way in which the system on which the software will be developed is supposed to be decomposed is describd by the development view.

By then, you have to construct a document, with a very small ( no more than 10 lines) executive description, and no more than two A4...
