Memory Cards are a way of storing digital information, from words to figures to images in various devices, from mobile phones, to digital cameras to GPS receivers and even game consoles. The Memory Stick is different in format and design. In size and shape it resembles a disposable cigarette lighter, so be careful if you are having clearing out your desk after giving up smoking. The USB Memory Stick is used to carry data, usually from a personal computer or laptop. It is easy to move data from one computer to another without sending it via email or copying it onto a disk. You fit it into the USB port on your computer, copy the data across, remove the memory stick and fit it into the computer that you want to copy the data across to. These memory sticks are so popular that they are handed out in meetings instead of great piles of paper. Everyone can then plug the memory stick into their own computer or laptop and be reading from the same hymn sheet so to speak. Giving away memory sticks means that users are looking for low price memory, lots of megabytes at the least cost. If you go online and key in low price memory you will find that there are whole websites devoted entirely to selling you low price memory. And memory sticks vary hugely in price depending on how much memory you want on them. If you are only dealing in documents with words or figures on, then you will not need much memory. But when pictures are involved you will need a whole lot more. A good print quality picture should be at least 3 Mb in size. For just a couple of dozen pictures you will need a memory stick with at least 120 MB.
