Which device is primarily used to store information on the go?

• A. USB flash drive
• B. RAM
• C. Internet
• D. Software

Answer: (A)

Portable storage means keeping data on a device you can carry with you and use with different machines. A USB flash drive fits that role perfectly: it's small, removable, and uses flash memory to hold files, so data remains intact even when the device isn’t powered and you can plug it into any computer with a USB port to access or transfer information. RAM, on the other hand, is fast, volatile memory used by the computer while it’s running; it loses everything when the power is off, so it’s not suitable for keeping data on the go. The Internet isn’t a device and doesn’t store data locally; it’s a network that can enable access to remote storage, but the question is about a portable device for storing information. Software refers to programs, not storage hardware. So the USB flash drive is the best choice for on-the-go storage.
