Q. Which one of the following words/phrases is most appropriately used to denote “an interoperable network of BD virtual worlds that can be accessed simultaneously by millions of users, who can exert property rights over virtual items”?

Explanation:

Metaverse

The term “Metaverse” refers to a collective virtual shared space, created by the convergence of virtually enhanced physical reality and physically persistent virtual space, including the sum of all virtual worlds, augmented reality, and the internet. It is an interoperable network of 3D virtual worlds that can be accessed simultaneously by millions of users, who can exert property rights over virtual items. This concept aligns perfectly with the description provided in the question.

– (a) Big data analytics refers to the process of examining large and varied data sets to uncover hidden patterns, unknown correlations, market trends, customer preferences, and other useful information.

– (b) Cryptography is the practice and study of techniques for securing communication and data in the presence of adversaries.

– (d) Virtual matrix is not a commonly used term in this context and does not specifically denote the described interoperable network of virtual worlds.

Therefore, the most appropriate term is “Metaverse.”
