What is the main purpose of the Random Access Memory (RAM) in a server?

The main purpose of Random Access Memory (RAM) in a server is to provide temporary storage for data being processed. This volatile memory type allows for quick read and write access, which is crucial for the efficient operation of applications and processes running on the server.

When a server operates, it loads active data and applications into RAM from the slower permanent storage (like hard drives or SSDs). This rapid access significantly enhances processing speed and performance since the CPU can retrieve and manipulate data much faster from RAM than from other storage types. Once the server is turned off or restarted, all information in RAM is lost, emphasizing its role as a temporary workspace rather than permanent data storage.

In contrast, other options address functions that are not performed by RAM. For example, storing permanent data and applications is handled by hard drives or SSDs, while connecting the server to a network is managed by network interface cards. Electrical power supply management involves power supply units (PSUs) rather than RAM. Thus, the role of RAM is distinctly centered around its function as active memory for processing tasks, which aligns with the correct answer.
