Final answer:
The cloud operates by running on server farms, not by being restricted to a supercomputer, leased line networks, relational database, or rotating disk technology. It comprises a network of remote servers used for storing, managing, and processing data over the Internet. The correct answer is option C. Requires leased line networks
Step-by-step explanation:
The question "The cloud ________." is best completed with the option "Runs on server farms." The cloud refers to a network of remote servers hosted on the Internet and used to store, manage, and process data, rather than a local server or a personal computer. These servers are often hosted in various geographic locations and are collectively known as server farms due to their scale.
Server farms are an essential component of cloud computing. They provide the computing power and storage capacity that allow users to access applications and services remotely over the Internet. Cloud services can be scalable, meaning they can be expanded to handle increases in demand without the need for each user to invest in physical infrastructure. To address part B of the options provided, while a supercomputer is a type of powerful mainframe computer designed to perform complex computations, the term 'the cloud' is not specific to supercomputers but encompasses a wider range of computing resources and services accessible over the Internet.
The other options, such as C "Requires leased line networks," D "Is restricted to relational database," and E "Is standardized on rotating disk technology," do not accurately describe the cloud. Cloud services can be accessed over various types of network connections, including more common broadband connections, and are not limited to leased lines. The cloud also supports various types of databases, not just relational ones. Finally, cloud storage technologies include solid-state drives (SSDs) and other modern storage technologies, not just rotating disk technology.
