someone help me please
A (20) For each of the following systems list the applicable structural and control style(s) of system architecture covered in class (e.g., repository, client-server, three-tier client server, abstract machine model, centralized, event-driven) Justify your answers a (An electronic chess companion), b (An airplane flight simulator for a video game), c (A floppy disk controller chip), d (A sonar system) B (80) In a situational awareness system officers such as police officer or fire fighter, have access to a wireless computer that enables them to interact with a correspondent. The correspondent can in turn visualize the current status of all its resources, such as police cars or trucks and call a resource by issuing commands from a workstation. Use case name: Report Emergency Participating Actors: Initiated by the officer and communicates with correspondent Flow of Events 1. The officer activates the "Report Emergency" function of her terminal 2. System responds by presenting a form to the officer 3. The officer fills the form by selecting the emergency level, type, location, and brief description of the situation. The officer also describes possible responses to the emergency situation. Once the form is completed, the field officer submits the form 4. System receives the form and notifies the 5. The correspondent reviews the submitted information and creates an incident in 6. The system displays the acknowledgement and the correspondent the database. The correspondent selects a response and acknowledges the report. selected response to the officer. Precondition: The officer is logged into the system Postcondition: The officer has received an acknowledgement and the selected response from the correspondent, OR the officer has received an explanation indicating why the transaction could not be processed.Explanation / Answer
ANSWER
a)
An electronic chess companion:
It's technique is more like a client - server model, which uses a depository where in sequence related to all the achievable moves are store.
When the user (client) makes a move about, the request goes to the head waiter to get the next move about from the processor.
The server at this time can either be on the narrow machine or on the cloud or on a little remote machine.
The server in turn uses the warehouse to fetch the best promising next move.Since, striking the next possible move requirements some logic to be execute, this architecture might grip a three tier client server as a substitute of only just a client head waiter.
b)
An airplane flight simulator for a video game:
The expression simulator wealth a machine that creates a sign or a model of something. So, the construction of an airplane flight simulator might look more like an abstract machine model.
This simulator is human being used for a cartridge game which in turn capacity have a client-server or a three tier client maître d' architecture.
c)
A floppy disk controller chip:
This is more like a warehouse. Just like how requests are send to the repository to fetch and practice the data, similar operation happen on a floppy disk manager IC.
d)
A sonar system:
Such system extra over and over once additional than not go after SDR structural design(Software defined radio). A very chief SDR structure might consist of a personal chip set with a noise documentation, or second analog-to-digital converter, go before by a number of outline of RF have front on come to an end
Important amount of signal dispensation are handed larger than to the general-purpose mainframe, rather than person being done in special-purpose hardware (electronic circuits).
Such a plan produce a radio which can take release of and transmit widely miscellaneous radio protocol (now and then referred to as waveforms) base only on the software old.
