+# Отчет по лабораторной работе №4
+
+Выполнила студентка гр. ИСЭбд-41 Воронкова Е.С.
+
+## Прохождение tutorial
+
+Установила RabbitMQ server и erlang
+
+Прохождение туториала 1:
+
+Сначала был запущен receiver, который становится в ожидании сообщения. Затем запустили с отдельном терминале sender, который отправил сообщение 
+
+![](images/screen_1.png)
+
+![](images/screen_2.png)
+
+Прохождение туториала 2:
+
+Открыли три терминала: в первых двух запустили поочередно receiver. В третьем терминале запустили sender и отправили пять сообщений.
+![](images/screen_3.png)
+
+В результате эти сообщения были распределены между двумя receiver.
+

+

+
+Прохождение туториала 3:
+
+Сначала в первом терминале запустили receiver, затем во втором запустили sender, и отправили сообщение
+
+![](images/screen_1.png)
+
+![](images/screen_2.png)
+
+## Разработка демонстрационных приложений
+
+Предметная область:медицина
+Запустили приложения по одному экземпляру:
+
+1. Sender
+
+![](images/screen_6.png)
+
+2. Receiver_Slow.
+
+![](images/screen_8.png)
+
+3. Receiver.
+
+![](images/screen_7.png)
+
+## Результаты выполнения лабораторной работы
+
+Результат отработки Receiver_Slow:
+
+![](images/screen_11.png)
+![](images/screen_12.png)
+
+Результат отработки Receiver:
+
+![](images/screen_9.png)
+![](images/screen_10.png)
+
+Вывод: Receiver принимает сообщения гораздо быстрее, чем Receiver_Slow тем самым не позволяя очереди накапливать огромное количество сообщений.
