Eria, I think freelancing is a part of the big world of online business. Online business can range from owning a professional webpage/ product to the part-time jobs like ad-typing, surveys completion, email reading, etc etc. Freelancing is a part of online business where you use the internet to advertise your availability for a particular job. Infact, freelancing online is no way different from the freelancing offline. Online, you get access to the entire world; offline, you are restricted to a certain zone. Time is another factor. Things happen faster online than offline. I guess I can put it this way: Online business is the father (or mother??). Freelancing is one of the many children that online business bears :-)
