Understanding unsecured business loans

I might have been absent from uni class when the teacher was discussing unsecured business loans. I am lucky enough to have a personal banker who explained this to me before I took out my loan. With a clear understanding of how this works and what it entails, I am more confident about knowing the fine print of my contract. The next time I am faced with a banking definition dilemma I will not hesitate to ask my personal banker to explain. Either I do that or ask my best friend, who is a bank manager - surely she will know the answer!
