Answer:
The storage area network basically apply in the networking model for storage various application in the data center. The storage area network (SAN) provide the common pathway between the server and the storage device.
The storage area network technology basically implemented in the fiber channel configuration over the ethernet. SAN provide access to the data that shared by the personal resources. It is basically simple and dedicated network which provide for the data storage.

Explanation:
Big data refers to huge collections of data that are difficult to process, analyze, and manage using conventional data tools. It is a core component of the 3rd platform, which also includes cloud computing, mobile devices, and social networking. The five Vs of big data are high volume, high velocity, diversified variety, unknown veracity, and low-density value. Although SQL and relational databases can be used for big datasets, a collection of alternative tools referred to as NoSQL has become popular. These tools work well when databases scale out (horizontally) and when databases are broken into subsets called shards. Modern database tools also handle dynamic scaling as devices are added when additional capacity is required. NoSQL tools are sometimes said to create schema-less databases, but they usually have some type of structure, though it may be more flexible than the relational model. A key-value data model provides each data element with a key. A column-oriented data model makes it easy to access data stored in similar fields, rather than in individual records. Two very popular NoSQL tools include Hadoop, which is a big data file system, and MapReduce which sends processing logic to the data, rather than bringing the data to the computer that performs the processing.
Answer:
hybrid topology
Explanation:
The type of topology that is being described is known as a hybrid topology. Like mentioned in the question this is an integration of two or more different topologies to form a resultant topology which would share the many advantages and disadvantages of all the underlying basic topologies that it is made up of. This can be seen illustrated by the picture attached below.
