Ports are one method by which a tablet communicates with other devices, others being WiFi and Bluetooth. What ports a tablet has can therefore be rather important.
The Dragon Touch Y88X has a micro USB port which will allow it to be connected to computers and laptops and upload or download files to and from them. This port can also be used to charge the battery, but the Y88X also has a separate AC charger port that will also charge the battery.
It also has a micro SD card slot which will take memory cards and expand the available storage, front and rear facing cameras and a speaker.
