Application Layer:
In this week the topic of the discussion is the application layer. The application layer
has the ability to establish a communication with the services and with the devices that are on
the internet or the local network. Most of the popular websites like the Google maps,
Facebook, pizza hut app, and the Google search engine uses the application layer. Among the
users that are local level and access the application layer are the faxes of the network,
