Publication venues for science and engineering can be divided into two broad categories - conferences and journals. Both provide opportunites to share research with pros and cons.
Conferences have many advantages over journals. The bar for entry is lower which encourages earlier versions of research. And, in turn, more disucssion about topics of interest. Another bonus is the opportunity to travel to attend the conference and network with other researchers in the field. The downside is that conferences are not held with as much regard as journals in most topics.
Journals are better preserved and archived. Articles published in highly selective journals dramatically boost the quality of a cv or grant application. However, publishing an article in a journal is a long and grueling process designed to weed out all but the best papers. This difficulty deters many people from journals.
It is necessary to publish in both conferences and journals since they provide vastly different experiences. Don't focus on one or the other completely.
