Certainly, Conference papers are a faster way to advertise ones' research. However, a problem with conference papers is that at many places, papers published as conference proceedings are not accepted for promotion, yet in some places where it is accepted for promotion it is given less credit than a article published in a journal.
It depends on your field. I have heard statements to the effect that in many branches of computer science the papers from prestigious conference carry more weight than journal papers, so you should perhaps ask your colleagues which is the situation in your subfield.
Scientists and research students are attracted to conferences because of the lure of easy acceptance of their abstracts or papers. Before sending papers to such conferences, you should check some important aspects.
Conference reports are normally not subjected to peer review, and because of any real quality control, most publishers and institutions give “Conference Proceedings” paper a low status only. If the conference reports are not in full proceedings form (papers with the IMRAD structure, peer reviewed, and with the questions and answers at the conference), it is not considered as a valid publication. If the report is in “abstract” or “extended abstract” form, it is clear that it is not validly published; therefore, you should publish the data in a regular primary journal.
