Final answer:

Routers at Layer 3 of the OSI model route packets, have built-in security functions, and determine the best paths between networks.


Explanation:

Routers operate at Layer 3 - Network Layer of the OSI model and route packets across different networks. They find the best path between networks by consulting routing tables and have a built-in security function to filter network traffic.

Routers have their own operating system with a powerful central processing unit, memory, and storage. Wirelessly, they are now dominant in households and small businesses, and misconfiguration can lead to network issues.

They determine the best path for packets, shared with other routers globally, and come in different sizes based on bandwidth handling and allow configuration of Access Control Lists (ACLs) for packet rules within networks.
