Mobile device. A mobile device (or handheld computer) is a computing device small enough to hold and operate in the hand. Typically, the device has a either flatscreen display with a small numeric keypad or alphanumeric keyboard, or a touchscreen providing a virtual keyboard and buttons (icons) on-screen.
On a typical USB cable, the Type A connector, aka the A-male connector, is the end that goes into a host, such as a computer. And on a host, the USB port (or receptacle) where the Type A-male is inserted, is called an A-female port. Type-A ports are mostly in host devices, including desktop computers, laptops, game consoles, media players and so on. There are very few peripheral devices that use a Type-A port.
