If adb is enabled on a phone in developer mode, adb can also be accessed 
over
TCP with SSH-like public key authentication of the PC.

But in regular consumer mode, the primary option is the USB protocol built
into Android, which for somewhat recent Android versions is the "MTP"
protocol originally designed for MP3 players and digital cameras, but in
early Android versions was the "USB disk" access to raw blocks of the SD
card inserted into the phone and implicitly unmounted by Android when the
USB cable was connected.

Enjoy
