Welcome to Pprune Wannabees!
You will find a large number of professional pilots here who are pleased to help someone get a first foot on the ladder to becoming one of their 'own'!
However they do expect posters to have done some research themselves and to have taken steps to acquire professional instruction to prepare them for the exams.
You have posted many 'basic' questions that would explained at any ground school. I recommend that you read through the threads regarding Distant Learning Courses (given your location) and enrol in the school of your choice. All the schools have tutors who can answer your questions without you having to show your lack of knowledge/understanding on a public Forum.
