Answer 2

Answer:

• A plug-and-play portable storage device that employs flash memory and is small enough to hang from a keychain is referred to as a USB flash drive.
• It is also referred to as a USB stick, USB thumb drive, or pen drive. An alternative to a compact disc is a USB flash drive.
• The computer's operating system (OS) recognises the flash memory device when it is plugged into a USB port as a detachable drive and gives it a drive letter.

• A USB flash drive can be used to launch an operating system from a bootable USB, store crucial files and data backups, transport preferred settings or programmes, perform diagnostics to diagnose computer issues, and more.
• The drives are compatible with a wide range of BIOS boot ROMs, Linux, MacOS, and Microsoft Windows.
• In 2000, the first USB flash drive with an 8 megabyte storage capacity hit the market (MB).
• Depending on the manufacturer, drives currently have capacities between 8 gigabytes (GB) and 1 terabyte (TB), with future capacity levels anticipated to reach 2 TB.

• There are no moving parts and negligible power consumption in USB flash devices.
• The gadgets, whether they are covered in plastic or rubber, are normally waterproof and sturdy enough to endure mechanical shocks, scratches, and dust.

• When a USB flash drive is unplugged from a computer or when the computer is turned off while the drive is still plugged in, data on the drive can be maintained for a very long time.
• This makes a USB flash drive practical for backup purposes or for transferring data between desktop and notebook computers.

• USB flash drive is different from most removable drives in that it doesn't need to be rebooted after being plugged in, doesn't need batteries or an external power source, and is platform independent.
• The device can be used with older systems without USB ports thanks to extra features that certain manufacturers offer, including password protection and downloadable drivers.

• The limitations on how many write and erase cycles a USB flash drive can withstand before failing, as well as data leakage and malware exposure, are drawbacks.
• Because the gadgets are movable and challenging to track, data leakage is a problem.
• When the device is connected to an infected system, malware can cause a security breach.
• However, common methods for preventing a security compromise include encryption and a regular scan of the USB flash drive.
