What aspect of memory does RAM improve upon?

RAM, or Random Access Memory, primarily enhances data access speed within a computer system. It is designed for fast read and write operations, enabling the processor to retrieve and manipulate data much more quickly than if it were accessing information from traditional long-term storage devices like hard drives or SSDs. By storing frequently accessed data and applications temporarily, RAM allows for improved performance and responsiveness, especially during multitasking scenarios where immediate data retrieval is critical.

The other options do not accurately reflect the unique contributions of RAM. While long-term storage, security of data, and capacity for saved files are important aspects of computer memory management, they are primarily functions of other storage technologies and not directly influenced by RAM’s characteristics.
