Best Answer Explained in Below-:

In the context of computing and network environments, servers are specialized machines designed to handle specific tasks and services over a network. Their primary functions include processing and managing requests from client devices, such as file storage, data sharing, and application hosting.

Let's examine the given options:

A) **E-mail processing**: Servers, specifically mail servers, manage sending, receiving, and storing emails. This service is essential for communication in both personal and business contexts.

B) **Database sharing**: Database servers facilitate the storage and retrieval of data for multiple clients simultaneously. They are crucial in managing large datasets accessed by various applications.

C) **Storage**: File servers provide storage solutions for users on a network, allowing them to save and access files from a centralized location.

D) **Word Processing**: Unlike the other options, word processing is typically performed on client machines using software like Microsoft Word or Google Docs. It involves creating, editing, and formatting text documents. This function is not server-based, making it distinct from the core tasks of servers.

Therefore, the correct answer is D) Word Processing, as it does not represent a function typically performed by servers. Servers facilitate collaborative environments, but the act of word processing itself is primarily done on end-user devices.
