Final answer:
PtoP topology is commonly used in computer networking to enable direct communication between devices without the need for a central server or hub.
Step-by-step explanation:
PtoP, or point-to-point, topology is commonly used in computer networking.
This type of topology is a connection between two devices, where data is transmitted from one device to another directly. It is often used in scenarios where devices need to communicate with each other without the need for a central server or hub.
For example, in a peer-to-peer file sharing network, each device is connected to another device directly, allowing them to share files directly between them.
