What is a "memory card"?

TJ McClearin (Business Manager, Infinity Wireless, LLC) gives expert video advice on: What is a "memory card"?; What is a "network storage device" or "NAS"?; What is "file transfer protocol" (FTP)?

A memory card is a device that you can put into your smart phone or PDA that allows you to expand the memory of your device. Whether you use that memory to store pictures or video depends on the size of the memory card that you buy. If you buy a smaller memory card, you're only going to be able to fit a smaller amount of data on it. You're not going to be able to fit a two-hour movie on a memory card that only stores 128 Megabytes; you'll need something that stores a gigabyte. The size of memory card reflects the cost that you're going to pay for it.
