In last class, I know the output and input of a computer and the storage of computer. When I first touched the flash drive, I know people always called it “reader”. It just likes USB drive. People insert the single-chip of cell phone into this “reader”, and then insert “reader” into USB socket. Therefore, people can transmit and read the information between two different cell phones. It is another way to change information.There are some different style and shape readers, such as CF reader, SM reader, PCMICA reader, memory reader, USB reader and double deck reader. When we use a kind of electronic equipment, we need a kind of material storage which is used for changing data. The semiconductor reader can achieve this goal. The Flash RAM is popularly used now, because it has potable, shockproof function. It is used in digital camera, cell phones, MP3 and PDA. With the appearing of electronic reader, more and more various chip cards which are sold in the market can be read, such as Smart Media, Compact Flash, Memory Stick, Multi Media Card, SD Memory, IBM Micro drive and Micro SD Card. If we lack such a “reader”, we can’t change and share the information very quickly and fluently.
The advantage of the reader is magical, but it doesn’t read the software, it reads different flash cards. It is a new kind of storage tool, and it is designed to provide convenient way for storage.
