+Whenever you want to access the same data on different devices without carrying it (the data) from device to device, with, let’s say, a thumb drive, you have multiple options for achieving this.

+**Peer to Peer** enables users to share content (files, messages, ...).
+While it does not rely on a central server, it comes with the big trade-of that the device storing the data you want to access has to be reachable and online.
+Today Peer to Peer is still widely used with VoIP and decentralized networks for censorship-resistant transactions formaly known as the blockchain.
+
+The **Client-Server** model evolved into the sophisticated "web-services" we know and use daily.
+One central powerful computer (the server) stores data and allows external devices (clients) to access it.
+
+For our course "Programmierprojekt" we are required to use the Client-Server model.
