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.
I believe it is b “Broadly speaking, modularity is the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use. ... However, the concept of modularity can be extended to multiple disciplines, each with their own nuances.”
A DBMS acts as a conduit between the database and the applications that will use it, enabling users to access, modify, and control how the data is arranged and optimized.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of relational databases. Data items are requested from the database by application programs, which are created using a combination of the DBMS's data manipulation language and a traditional programming language. The DBMS locates and provides the data elements requested by the application programs.

Answer:
The answer to the following question is the option "b".
Explanation:
In the computer system, Hard disks stand for the hard disk drive. It is also known as a hard disk. It locates inside the computer case. The hard disk drive is used to store an electromechanical data. That uses magnetic storage device that store and retrieve data. So the answer to this question is hard disks.
The answers true hope this helped :)
