Which component of a computer is responsible for temporarily storing data being accessed by the CPU?

The component of a computer responsible for temporarily storing data being accessed by the CPU is RAM, or Random Access Memory. RAM serves as the primary memory in a computer system, allowing for the rapid access and transfer of data needed for active processes and applications.

When a computer runs programs, it needs to access data quickly. The CPU retrieves instructions and data from RAM because it is significantly faster than storage devices such as hard drives or SSDs (Solid State Drives). The volatile nature of RAM means that it loses all stored information when the power is turned off, but while powered, it provides the necessary space for executing tasks efficiently.

In contrast, a hard drive and an SSD are used for long-term data storage. They hold operating systems, applications, and user data but do not provide the same level of speed needed for immediate processing tasks carried out by the CPU. Cache memory also plays a role in data storage but operates at a lower level, closer to the CPU, providing even faster access for frequently used data. However, RAM is the main component associated with temporarily storing data being accessed by the CPU during operation.
