Which type of memory is used for temporary storage while a computer is running?

RAM, or Random Access Memory, is the correct answer because it serves as the primary temporary storage for a computer while it is operating. Unlike other types of memory, RAM is volatile, meaning it loses all stored information when the power is turned off. This transitory nature makes it suitable for managing data that the CPU needs to access quickly as it executes programs.

RAM is designed for speed, accommodating the rapid read and write cycles required by active applications and processes. It allows multiple applications to run simultaneously by providing them with the necessary space to store and manipulate data efficiently.

In contrast, ROM (Read-Only Memory) is permanent storage that retains information even when the power is off, making it unsuitable for temporary data storage. Flash memory is often used for long-term data storage and can retain information without power, similar to ROM, but it is not appropriate for temporary use while the computer is running. Auxiliary memory refers to external storage devices like hard drives or SSDs, which are also not meant for temporary storage during operation, as they are primarily used for long-term data retention. Thus, RAM is the ideal choice for temporary storage in a functioning computer system.
