Flash RAM is a special kind of memory that most Palm devices use to store the operating system. It has the advantage of allowing operating system upgrades, and it is also used in digital cellular phones, digital cameras, LAN switches, PC cards, digital set top boxes, embedded controllers, and other small devices. An embedded system, like Embedded Linux, does not require a disk drive, although a number of other memory organizations are possible. So if, let's say, Linux runs out of flash memory, it may use part of the flash memory as a read-only file system to store extra programs and static data.
Imagination is the beginning of creation. You imagine what you desire, you will what you imagine and at last you create what you will.
