An example of such memory is RAM (Random Access Memory), which is volatile and loses its data when the power is turned off.

1. Solid-state drives (SSDs) consume less power compared to hard disk drives (HDDs), which extends battery life.
2. SSDs offer faster data transfer rates, improving overall performance and responsiveness of the device.

Blu-Ray storage is popular because it offers a larger storage capacity than standard DVDs, allowing for high-quality games that require more data. Additionally, it enables faster load times and better graphics.

1. The camera can be connected to the PC via USB cable, enabling direct file transfer.
2. The SD card can be removed and inserted into a card reader connected to the PC for data access.

1. Text-to-speech functionality that reads text aloud for users with visual impairments.
