Module Testing: Module testing is unit testing, i.e. testing a particular module...Normally a project is divided into smaller chunks known as modules, testing these modules individually to test if they are working individually is known as Module Testing.

System Testing: Testing the whole system is System Testing. Simple! Isn't it!

Hope this answers your question!

System Testing
In System Testing we test the whole system ie. it is an end to end testing.

- Testing whether the whole system is designed as per the client requirements.
- System Testing is basically done only after the module testing and integration testing are completed.
- In System testing the same as production environment is simulated and test cases are executed in the same as client environment.
- In system testing we do perform testing based on both the functional and non-functional(FURPS) requirements

Module Testing
It is nothing but the Unit Testing. Each unit or screen is  validated.

- Testing the every units present on screen (like controls, fields, data length etc) on a screen
- It is basically done in the Development environment itself.
