    It makes no difference if you are using a phone, laptop, tablet or PC etc., the overall transfer of data is roughly the same.

    As far as the program or app requesting data is concerned, it "sees" a connection to whatever server or machine the information is stored on; that's handled by the networking part of the operating system.

    When that distant machine replies with blocks of data, it's down to the program/app to interpret that information appropriately; streaming audio, video, web page tex, image, email etc.

    The two also "handshake", to control how fast data is transferred and pause if it's coming in faster than being used or can be stored.

    The actual media the data travels over will likely be wired ethernet & optical fibre part of the way, and modulated on radio frequency carriers for DSL, cable, WiFi or 3G/4G/5G links.

    It's always "data", but the physical coding or transport method likely changes a number of times between the ends of the data connection.

    Files are sent by radio signals.

    Data has to be generated before it can be sent as a signal.
