An external device refers to any device that is connected to a computer system that is usually a remote or subordinate device. It is designated by specifying a number that distinguishes it from all other devices connected to the computer.
On the other hand, an external drive is a hard disk drive or solid-state drive that connects to the outside of the computer instead of the inside. It can be powered by its own data cable or require an AC power connection to function. An external hard drive is like an internal hard drive that has been removed, given a protection case, and connected externally to the computer.
FAQs:
What are some common external devices?
Some common external devices include printers, scanners, cameras, microphones, speakers, and external hard drives.
Do external hard drives perform as well as internal hard drives?
External hard drives can perform as well as internal hard drives when connected through a fast interface such as USB 3.0 or Thunderbolt. However, if the external drive is connected through a slower interface, performance may be affected.
What are the advantages of using external drives?
External drives provide additional storage space for a computer system. They can also be easily transported and used on different systems without the need for installation. External drives can also serve as a backup for important data.
Conclusion:
External devices and drives are important components that add functionality and convenience to computer systems. External drives provide benefits like extra storage space, portability, and a backup solution. While external hard drives can perform as well as internal hard drives, it ultimately depends on the interface used for connection.
