What Is A Usb Flash Memory
Thursday, April 15th, 2010
A USB port or Universal Serial Bus port is an interface of a computer with small rectangular 4- wire external ports ideal for both data transfer as well as power supply. Data transfer is made possible through peripherals like usb flash memory and others of the sort. The two interfaces possible are 1.1 and 2.0 according to the speed ratings for USB. The most common in use, 2.0 interface tops to 480Megabits/second, while the former had only 12Mbs. Flash memory is non- volatile, solid state computer storage used for storage and transfer of data. It is electrically programmable and erasable, and therefore, a type of EEPROM. Before, storage through this sort of memory required erasing of the entire data on the chip, which took pretty lot of time. A special type of flash EEPROM has an in built wiring circuit to rectify this problem. Now that erase can be done at once in blocks, rewriting is made easier and faster. This is what makes usb flash memory unique. This fast read access in combination with durability of the drive is the root causes of its popularity. Forget those technicalities of diodes, wirings and memory- this is the technology of today ought to make us live an easier life.
