What is classified as an external storage device?

An external storage device is defined by its ability to be easily removed from a computer system and its portability, which allows users to transport data conveniently. Examples include USB flash drives, external hard drives, and SD cards. These devices connect to the computer through interfaces like USB, providing a simple way to add extra storage capacity or to back up important files.

In contrast, permanent internal storage mechanisms, such as hard drives or solid-state drives installed inside a computer, are not considered external since they are not easily removed and are integrated into the system. Networking equipment and devices that enhance processor speed serve different functions and do not fit the classification of storage devices at all. This distinction is crucial for understanding the various types of storage options available and how they can be utilized in computing environments.
