What is one common storage medium for data at rest?

One common storage medium for data at rest is hard drives. Hard drives are designed to store large amounts of data persistently, meaning the data remains on the device even when power is turned off. They use magnetic disks to read and write data, making them an essential component in computers and servers for long-term data storage.

In contrast, RAM (Random Access Memory) is a volatile memory used for temporary data storage while a computer is running, meaning it loses all stored information when the power goes off. The GPU (Graphics Processing Unit) is primarily focused on rendering images and handling graphic tasks and does not serve as a primary storage medium. The CPU (Central Processing Unit) is the brain of the computer, processing instructions but not directly storing data long-term. Thus, hard drives are the appropriate choice for data that needs to be preserved over time.
