I'm new to QGIS. I have a layer containing all the points of interest. I will like to divide a city into different zones (service area) depending on the location of these points so that each zone will be served by each point. How do I go about doing this in QGIS?

One method might be to create Voronoi polygons around your points. Then Clip the resulting Voronoi polygons to the shape of your city boundary.
Of course, these 'zones' would only be the areas in your city closest to the original points and would in no way consider population densities, driving routes, drive times, or other geographical features that question the usefulness of the Voronoi.
