also whats the difference between a flash stick and a memory stick?
A flash stick tends to be a simile for flash drive, pen drive etc whereby the memory is in such a form that it can be plugged into a USB slot and the operating system recognises it as a new removable hard drive.
A memory stick tends to be a different way of referring to the various different memory cards, SD, Compact Flash, MMC etc, which all require a card reader of some sort so that the system can recognise them as a removable drive. It was a name originally coined by Sony for their proprietary flash memory e.g. Memory Stick Pro, Memory Stick Duo etc.
Having said that the names you asked about can also be interchangeable with the two definitions above. It all depends on who's using the expression (their technical knowledge) and in what context.
