I assure you that I won't include additional jargon to complicate things.
All people possess these 8 functions in their mind. To better engage with this series, you may consider how you might engage these functions in your everyday life.
What is introverted and extraverted functions in MBTI?
First, set aside the idea of labelling individuals as introverts or extroverts. The I/E dichotomy in the MBTI tests have led to too much stereotyping.
Cognitive functions can be categorized as introverted or extraverted. A strong test for this is to close your eyes and remain still for a moment. Everything occurring within you—such as the flow of your emotions, your thoughts, bodily sensations (like hunger), and your imagination—is considered introverted.
Conversely, activities that involve external elements, like interacting with objects, expressing your thoughts to others, venting your emotions, and discovering connections between various events on Earth, are extraverted.

Aren't some activities include both extraverted and introverted cognitive functions?
You got it! Certain activities engage both extraverted and introverted functions. For instance, reading a book involves an extraverted function. You can close your eyes to read the book, don't you? However, as you process what you read, sense the conveyed atmosphere, and reflect on yourself, you're engaging introverted functions.
What's important is that these processes can vary for different individuals. Some people may find it easy to make sense of things but struggle with reading large amounts of text, while others may be comfortable reading a lot but find it difficult to understand what they've read. The difference here might imply the degree of development and the user's attitude towards certain cognitive functions. This acts as a clue for determining an MBTI type.
