What are expansion card slots?
The expansion card slot is a slot that can hold different types of cards, such as SD, MMC, or CF. These cards are small, inexpensive, and easy to plug in. Much like computer diskettes, they hold information for upload or download onto a handheld. With them, you can instantly add software programs, ebooks, large databases, graphics, or even video files to your handheld without sacrificing memory space. Some peripherals, like wireless cards, also connect through expansion card slots.
