"functional" describe the functions of the system

"non functional" describe the things that aren't functions of the system.

As per my knowledge goes these are the differences that I can think off...

Functional Testing : Testing the developed application against business requirements.

Functional testing is done by using the functional specifications provided by the client or by using the design specifications like use cases provided by the design team.

Functional testing covers:
1) Unit Testing
2) Smoke testing / Sanity testing
3) Integration Testing (Top Down,Bottom up Testing)
4) Interface & Usability Testing
5) System Testing
6) Regression Testing
7) Pre User Acceptance Testing (Alpha & Beta)
8) User Acceptance Testing
9) White Box & Black Box Testing
10) Globalization & Localization Testing

*********************************************

Non-Functional Testing: Testing the application based on the clients and performance requirement.

Non-Functional testing is done based on the requirements and test scenarios defined by the client.

Non-Functional testing covers

1) Load and Performance Testing
2) Ergonomics Testing
3) Stress & Volume Testing
4) Compatibility & Migration Testing
5) Data Conversion Testing
6) Security / Penetration Testing
7) Operational Readiness Testing
8) Installation Testing
9) Security Testing (Application Security, Network Security,
System Security)

Functional requirements are associated with specific functions, tasks or behaviours the system must support, mainly driven by FRS while non-functional requirements are constraints on various attributes of these functions or tasks and mainly driven by SRS/UC and different real time artifacts. It can be helpful to think of non-functional requirements as adverbially related to tasks or functional requirements: how fast, how efficiently, how safely, etc., is a particular task carried out by a particular system?

As far as I see the difference between Functional Requirements and Non Functional requirement is,

Functional Requirements are related to functionality of the system/application.
But Non functional requirements are more related to the performance of the system/application.

Not necessarily. Non-functional requirements can also include items such as adherence to specific development methodology, use of specific technologies, security considerations, etc... For example, I might have a mobile PDA base system that communicates with a back office system using mobile telephony. Some non-functional requirements here might include that the solution be CE.NET based, that the communications utilises a GPRS rather than an outdated GSM connection, and that a 128 bit over the air encryption standard used.

Note that definitions are liable to change between companies, and some requirements can be difficult to pigeon hole in this fashion.
