USB Flash Drive
Good morning ladies and gentlemen. My name is 000000. Today, I’d like to present about the USB Flash Drive. The purpose of this presentation is to inform you all about the general characteristics of the USB Flash Drive, how to uses USB Flash Drive and the advantages of USB Flash Drive. This presentation is divided into 3 parts. Firstly, I’ll be talking about the general characteristics of the USB Flash Drive. Secondly I would like to present you how to use USB Flash Divers. Finally I’ll show you the advantages of the USB flash drive. This presentation will last about 5 minutes and if you have any question, please feel free to ask me at the end of my presentation.
First of all, I would like to describe the general characteristics of USB flash drive. What’s USB flash drive? USB flash drive is a data storage device that uses flash memory to store data integrated with a USB interface. It’s typically small, lightweight, removable and rewritable.
