+## Intent
+Event Queue is a good pattern if You have a limited accesibility resource (for example: 
+Audio or Database), but You need to handle all the requests that want to use that.
+It puts all the requests in a queue and process them asynchronously.
+Gives the resource for the event when it is the next in the queue and in same time
+removes it from the queue.
+

+
+## Applicability
+Use the Event Queue pattern when
+
+* You have a limited accesibility resource and the asynchronous process is acceptable to reach that
