The term "multiple devices" refers to using or operating more than one electronic device at a time. This can include anything from smartphones, tablets, laptops and desktops, gaming consoles, smartwatches, and even IoT (Internet of Things) devices such as smart home appliances. The phrase is often used to describe the ability for users to access or operate their devices simultaneously, whether it be through a single user account on multiple devices, or by using different accounts on separate devices at once.
