You don't have much control over the first. If your internship happens to coincide with a position opening up or a department expanding, you might be lucky enough to be considered for the job. But whether you are, is up to you.
It's your performance that determines if you're kept on after you're internship is done. Even if you're lucky enough to be in the right place at the right time, the only way you'll be offered a position is if the company is happy with your performance as an intern. So treat every internship as a hands-on job interview. You just never know what might happen.
