'Das Tablet' is the electronic device. A pill or medication is called 'die Tablette' in German. Although the words sound similar, the meaning is completely different.
Der Arzt hat mir Tabletten gegen die Kopfschmerzen verschrieben.
The doctor prescribed me tablets for the headache.
When describing what you do with the device, you usually use the preposition 'auf' (on). You read, play, or watch something 'auf dem Tablet' (on the tablet).
Ich lese abends gerne die Nachrichten auf dem Tablet.
In the evening, I like reading the news on the tablet.
Common verbs used with 'Tablet' (tablet) are 'benutzen' (to use), 'einschalten' (to turn on), 'ausschalten' (to turn off), and 'aufladen' (to charge). These describe the basic handling of the device.
Bitte vergiss nicht, dein Tablet vor der Reise aufzuladen.
Please don't forget to charge your tablet before the trip.

'der Computer' and 'das Tablet' can both be devices used for digital activities, such as writing, reading, or searching the internet. However, 'Computer' is the more general word and often refers to a device with a keyboard, mouse, or many programs. 'Tablet' is more specific: it is portable and is mainly operated via a touchscreen. Learners may confuse the words because a tablet is also a type of computer. In everyday language, however, you say 'Tablet' when you mean exactly this flat device with a screen.
