I recently bought a new computer with a internal 6 in 1 flash memory card reader in it. Can some one tell me what it this and what it is used for?

A number of electronic devices use cards that are about the size of book of matches to store data. The cards contain electronic memory to store the data. This memory differs from that in your computer in that it will not forget what is on it when power is removed from it. In practice they act little computer disks. They have capacities from 8MB to 2GB. Different manufacture make them in different packages sizes which is why you have a 6-in-1 reader to accomodate the different ones. They are commonly used in digital cameras to store the pictures taken. After you take your pictures you remove the card from the camera and insert it into the reader. You can then view the picture on the card and copy the pictures to your computer. When are done with what is on the card you can erase them and fill them again.

Flash cards are a compact storage medium, looking like a thin, square chip with metal contacts exposed at one end (some pictures). They usually come in storage sizes up to 1GB. Flash cards are used in cameras, MP3 players, etc. for storage. Unfortunately, there are about nine flavors of cards (just look in any store). The different types are not too different, but they are basically incompatible with one another. Therefore, multi-type card readers are common, because no one wants to buy two different readers (like having two different types of floppy drives). Your memory card can be read much like a small hard drive with such a reader.
