What is the meaning of flash disk?
(1) See USB drive. (2) A storage module made of flash memory chips. Flash disks have no mechanical platters or access arms, but the term “disk” is used because the data are accessed as if they were on a hard drive. The first flash disks were housed in Type II PC Cards for expanding laptop storage.
What is the use of flash disk?
USB flash drives are often used for storage, data back-up and transferring of computer files. Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts.
How does a flash disc work?
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 in a similar fashion as conventional hard drives. Flash drives are non-volatile, which means they do not need a battery backup.
What’s the difference between a flash drive and a USB?
Answer: A USB hard drive is an external hard drive that connects via USB. A USB flash drive, sometimes called a “keychain drive,” also connects to the USB port on your computer. Unlike a USB hard drive, a flash drive is a “solid state” device, meaning it has no moving parts.
What are the types of flash drive?

- Flash memory-based CompactFlash (CF) card (including CFast card) and XQD card (Note: some other types of CF and XQD card are not flash memory-based)
- Memory Stick (MS)

What are 3 uses for flash memory?
Flash memory is used in computers, PDAs, digital audio players, digital cameras, mobile phones, synthesizers, video games, scientific instrumentation, industrial robotics, and medical electronics. Flash memory has fast read access time, but it is not as fast as static RAM or ROM.
What is the advantage of USB?
One of the main benefits of using USB cables is their ability to carry more information per second (12 mb/second) than parallel cables (115 kb/second). This means faster data transfer. Another advantage that goes with an USB cable is that its port is smaller than parallel cable port.
Are flash drives reliable?
Overall, flash drives can be more reliable than hard drives, but they have significant limitations. Features vary from one manufacturer to the next, and your usage habits can drastically affect drive performance. Always keep important data in at least three physical locations to avoid permanent data loss.
