The concept is very simple really. Linguistic competence is what you actually know about a language, and linguistic performance is how you actually use it. So if you make grammatical mistakes, but you know they are mistakes, then your performance does not match your competence. But if you don't know they are mistakes, then your competence matches your performance, and you are probably not native.
For example, in looking at the unanswered wiki questions close to this one:
How does pneumonia fit into Maslow theory?
If the questioner just made a type and knows that a native English speaker would say:
How does pneumonia fit into Maslow's theory
then his or her performance does not reflect his/her competence. If the questioner doesn't know that this is a grammatical error, then they lack linguistic competence in English.
We ca say that linguistic competence deals with the language structure, e.g. grammar, syntax ... etc. Whereas communicative competence is the knowledge of communication. It depends on linguistic cometence. The later focus on fluency rather than accuracy. Best Wishes Nawraa. From: Sultanate of Oman
Linguistic Stylistics focuses on linguistic theory whereas literary stylistics focuses on the interpretation of literary texts
What is common and different between linguistic schools?
The differences between Chomsky's is that it stresses the psychological. The Bloomfield on the other stresses competence. Bloomfield's ambition was to make linguistics a scientific disciple.

There is no difference at all in meaning, however "competence" is the most often used, as many are unfamiliar with the noun "competency" and sometimes consider it an incorrect form of the word.
Competence is what you are able to do. Performance is what you actually do.
Chomsky separates competence and performance; he describes 'competence' as an idealized capacity that is located as a psychological or mental property or function and 'performance' as the production of actual utterances. In short, competence involves "knowing" the language and performance involves "doing" something with the language. The difficulty with this construct is that it is very difficult to assess competence without assessing performance.

no difference. just the linguistic difference
Linguistic Stylistics focuses on linguistic theory whereas literary stylistics focuses on the interpretation of literary texts
Competence is the ability to do something successfully or efficiently. Intelligence is the ability to acquire and apply knowledge and skills.
there is no difference between high pressure and performance chromatography
Competence would be a ratio, Capacity is max amount, volume, etc..
display is something you see, however, performance is something you do.
Performance gap is the difference between current situation and intended situation.
Capability is the ability to perform actions. Competence is the ability to perform a specific task, action or function successfully. So if you use your capability with success it becomes your competence. ;-)
