Which of the following is a function of primary memory (RAM)?

Primary memory, specifically RAM (Random Access Memory), functions as a temporary storage space that allows a computer to access data quickly while it is in use. When applications are running or data is being processed, this information resides in RAM, which provides fast read and write capabilities essential for the smooth execution of tasks. This dynamic nature of RAM is critical because it enables the processor to retrieve data and instructions at high speeds, facilitating efficient computing.

The other options focus on functions that are not applicable to RAM. Permanent file storage is typically handled by secondary storage devices like hard drives or SSDs, which retain data even when the power is off. Managing user preferences usually involves software settings that can also be stored on secondary storage, while enhancing network capabilities is related to networking hardware or software, rather than the primary memory itself. Therefore, the role of RAM is uniquely tied to providing the necessary temporary storage for active processes during computation.
