WHAT IS A USB FLASH DRIVE?
A flash drive stores data using flash memory. Flash memory uses an electrically erasable programmable read-only (EEPROM) format to store and retrieve data. Flash drives operate similarly to conventional hard drives. Flash drives are non-volatile, which means they do not need a battery backup. Computer users may choose to use flash memory as an option for the easy storage and transfer of data.
HOW DOES A FLASH DRIVE WORK ON PCs?
Most computers come equipped with USB ports, which detect inserted flash drives and install the necessary drivers to make the data retrievable. Computer users can store and retrieve data once the operating system has detected a connection to the USB port. After the computer user has finished using the flash drive, he or she must then properly eject the device to safely remove it. The operating system prompts the user when it is safe to remove the flash drive from the USB port.
A flash drive has many components that make it operational. For instance, it has a printed circuit board (PCB) covered in a durable casing made of plastic or rubber. A USB connector protrudes from one end of the flash drive. Computer users connect this side of the flash drive to the USB port receptacle. Most flash drives come equipped with a type-A USB connection to make them compatible with standard receptacles.
Flash drives have a USB mass storage device classification, which means they do not require additional drivers. The computer's operating system recognizes a block-structured logical unit, which means it can use any file system or block addressing system to read the information on the flash drive. A flash drive enters emulation mode or acts as a hard drive, once it has connected to the USB port. This makes it easier to transfer data between the flash drive and the computer.
The main difference between hard disk drives (HDDs) and flash chips found in USB flash drives is the lack of moving parts, and the reduced risk of physical damage in the latter because of this. There is also a difference in the way flash drives writes and stores data; hard disk drives write data to platters in a linear fashion, to sectors of a standard size. USB flash drives, on the other hand, spread the individual pieces of data that form files all over the chip and can be found in several locations because of this. This can make data recovery quite tricky.
