An external hard drive is a data storage device that connects to a computer via a USB cable or other interface. It is typically used to store and back up large amounts of data, such as photos, videos, and documents. External hard drives are typically powered by the computer’s USB port or by an external power supply.
External hard drives offer several benefits over internal hard drives. First, they are portable, so you can easily take them with you wherever you go. Second, they are relatively inexpensive, making them a cost-effective way to expand your storage capacity. Third, they are easy to install and use. Simply connect the external hard drive to your computer and it will be recognized as a new drive.
