A data card switching method is provided. The method includes acquiring, by a data card switching apparatus, a port form flag of a data card; and sending, by the data card switching apparatus, the port form flag to the data card, such that the data card switches to a corresponding port form. Also, a data card and a data card switching apparatus are provided. A data card acquires a corresponding port form flag from a data card switching apparatus, and switches to a corresponding port form according to the port form flag, such that mode switching of the data card is performed without the need to upgrade data card software, thereby reducing maintenance costs of the data card.

In accordance with some embodiments, a method is performed at an electronic device with a display, radio frequency (RF) circuitry, and one or more input devices. The device displays a first user interface on the display. While displaying the first user interface, the device detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the device determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the device displays a pairing affordance that initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays information concerning coupling of the first peripheral and the second peripheral.

A data storage system includes a host, an adapter card, and a storage node. The host establishes a communication connection to the adapter card through a bus, and the storage node establishes a communication connection to the adapter card through a network. The storage node is configured to store data that the host requests to write into a first memory space. The first memory space is a storage space that is provided by the adapter card for the host and that supports memory semantic access. The adapter card writes the data into a second memory space of the storage node, where the adapter card includes a first correspondence between a physical address of the second memory space and an address of the first memory space.
