Introduction

In any device, the motherboard is the most important component of the system. It is the control center for everything in your tablet. This means that all connections have to go through it. Being the engine of the tablet, the motherboard itself holds everything together. If it is damaged or something spills on it, the tablet would not work. It is the main platform for communication between all other components in the device. The motherboard consists of various components which have their own roles to play in the functioning of the tablet.
