OSI Model
What layer of the OSI model is the Network layer? (e.g fifth layer, fourth layer)
The network layer is the third layer of the OSI model.
What are one of the many pros of the TCP/IP model?
helps establish a connection between different types of computers; works independently of the OS; supports many routing protocols; uses client-server architecture that is highly scalable; can be operated independently; supports several routing protocols; is lightweight and doesn't place unnecessary strain on a network or computer.
How does the network layer distinguish where to send the data it receives?
The network layer looks at the sender's IP address in order to find the data's destination.
What is the network layer ultimately responsible for?
Receiving and sending packets to their intended destinations.
What is the function called where the network sends data to a router?
Routing
How does the network layer pick and choose which router to send data to? (What does it use to figure this out?)
The network layer uses protocols to determine the best router.
