Networking fundamentals

Question 1

refers to any physical cable between two Ethernet nodes.

Answer 1

Ethernet Link

Question 2

step 3 of the Process by which a TCP/IP host sends data

Answer 2

Encapsulate the data supplied by the transport layer inside a network layer(IP) header.

Question 3

This layer defines three main features: logical addressing, routing (forwarding), and path determination. Routing defines how devices (typically routers) forward packets to their final destination. Logical addressing defines how each device can have an address that can be used by the routing process. Path determination refers to the work done by routing protocols to learn all possible routes and choose the best route.
