Review the following list of key terms:
- Address Resolution Protocol (ARP): A protocol that resolves logical IP addresses to physical addresses.
- Application layer: The layer of the TCP/IP stack that supports network applications and provides an interface to the local operating environment.
- Datagram: The data package passed from the Internet layer to the Network Access layer, or a data package passed from UDP at the Transport layer to the Internet layer.
- Frame: The data package created at the Network Access layer.
- Header: A bundle of protocol information attached to the data at each layer of the protocol stack.
- Internet layer: The layer of the TCP/IP stack that provides logical addressing and routing.
- IP (Internet Protocol): The Internet layer protocol that provides logical addressing and routing capabilities.
- Message: In TCP/IP networking, a message is the data package passed from the Application layer to the Transport layer. The term is also used generically to describe a message from one entity to another on the network. The term doesn’t always refer to an Application layer data package.
- Network Access layer: The layer of the TCP/IP stack that provides an interface with the physical network.
- Segment: The data package passed from TCP at the Transport layer to the Internet layer.
- TCP (Transmission Control Protocol): A reliable, connection-oriented protocol of the Transport layer.
- Transport layer: The layer of the TCP/IP stack that provides error control and acknowledgment and serves as an interface for network applications.
- UDP (User Datagram Protocol): An unreliable, connectionless protocol of the Transport layer.
