Play an AI-generated podcast conversation about this lesson

What is the main difference between human protocols and network protocols?

Human protocols are designed for machines, while network protocols are designed for humans.

Human protocols are governed by protocols, while network protocols are not governed by any rules.

Human protocols involve specific messages sent by machines, while network protocols involve specific actions taken when messages are received. (correct)

Human protocols define the format and order of messages sent and received among network entities, while network protocols involve communication activities among humans.

In the context of network structure, what do access networks primarily connect?

Access networks connect physical media to routers.

Access networks connect regional ISPs to global ISPs.

Access networks connect end systems to edge routers. (correct)

Access networks connect servers to clients.

What do protocol layers and service models define in a network environment?

Protocol layers define the security measures in a network, while service models define the throughput of data packets.

Protocol layers define the format and order of messages sent and received among network entities, while service models define the types of services offered in a network. (correct)

Protocol layers define the delay and loss in a network, while service models define the actions taken on message transmission.

Protocol layers define the physical media used for communication, while service models define the structure of end systems.
