What is Transistor

A transistor is a semiconductor, which consists of a thin central layer of one type of semiconductor material sandwiched between two relatively thick pieces of the other type of semiconductor. The central part is known as the base (b) and the pieces at either side are called the emitter (e) and the collector (c).

An interesting parameter is water resistance – one of these Pocketbook 641 Aqua 2 models is presented in the KTS online store catalog ., but from my own experience I can say that mechanical control buttons do not greatly reduce the comfort of turning pages or navigating through the library. Answering the question “Reader or tablet?”, I can say with confidence that it is not worth choosing between these two devices, they are completely different in their functionality. A reader will never replace a tablet, and a tablet, although it can be used for reading, will not be as convenient – it is better to have both devices and enjoy their capabilities.
