Answer 1

A router connects devices within the same network, forwards data between different networks, and manages network security.

Step-by-step explanation:

A router plays a crucial role in a network by performing several functions:

1. Connecting devices within the same network: A router serves as a central point of connection for devices within a network. It allows devices to communicate with each other and share resources.
2. Forwarding data between different networks: A router routes data packets between different networks, enabling communication between devices on different networks.
3. Managing network security: Routers often include security features such as firewalls, which protect the network from unauthorized access and help manage network security.

Therefore, options a), b), and c) are all correct in describing the role of a router on a network.
