Area 2

Name : The Application

Purpose :
There are 2 accounts types :
The professor account contains a personal data storage of 10GB. The professor will be able to see his schedule and his courses. For each course, the professor will be able to download the students' assignments and review them. All courses will be recorded, the professor will be able to show a file of his storage on the classroom's projector when connected to the LAN through the classroom's computer. If the course is online, the professor will be able to upload video.
The student account contains a personal storage of 1GB. The student will be able to access to the university computers by login to his session. The computers will not save anything, they just contain computer …show more content…
Data flows in a single direction, from one entity to the next. An entity accepts data in circulation on the ring only if it corresponds to its address. If not, the entity in question passes the data to the next entity. (https://fr.wikipedia.org/wiki/R%C3%A9seau_en_anneau)

In a star network topology, network devices are connected to a central hardware system (the node). The role of this one is to ensure the communication between the different equipments of the network. In practice, the central equipment can be a hub , a switch or a router.
The downside to a star architecture is that it is susceptible to traffic problems because the central computer is processing all of the messages. (https://fr.wikipedia.org/wiki/R%C3%A9seau_en_%C3%A9toile)

The latest implementation in Wide Area Network Architectures has actually existed in the supercomputer industry since its inception being that of the Mesh Architecture. In a fully connected Mesh each node is connected to every other node, and while this may be the ideal implementation it is also the most impractical since this has an exponential cost association the further apart the nodes are geographically from each other.
