6.5.3 Internet Protocol Facts

What is the primary protocol used for the internet called?

• Open Systems Interconnection Model

• Transmission Control Protocol/Internet Protocol

• Department of Defense Protocol

• Packet Switching Network Protocol

Who designed the set of networking protocols that became TCP/IP?

• The Internet Engineering Task Force

• The World Wide Web Consortium

• The government's Department of Defense

• The International Organization for Standardization

What method did the original TCP/IP protocols use to send data?

• Direct connection transfer

• Packet switching network

• Circuit switching network

• Broadcast transmission

What happens if a packet fails to arrive at the destination in the TCP/IP model?

• The packet is ignored.

• The destination computer requests the missing packet to be resent.

• The packet is permanently lost.

• The source computer is notified to stop sending packets.

What device is used to forward packets from one network to another?

• Modem

• Switch

• Router

• Firewall

What does the TCP/IP model focus on specifically?

• The functions in the Internet layer and the Transport layer only.

• The functions in all seven layers of the OSI Model.

• The functions in the Application layer only.

• The functions in the Physical and Data Link layers.

Which OSI Model layers are encompassed in the TCP/IP Model's Application layer?

• Application, Presentation, and Session

• Transport, Network, and Data Link

• Presentation, Session, and Transport

• Network, Data Link, and Physical

What is the primary function of the Transport layer in the TCP/IP model?

• To provide high-level protocols for applications

• To enable network services to operate on the network

• To be responsible for error checking and reliable delivery

• To integrate network functionality into the host operating system

What does the Transport Control Protocol (TCP) add to each IP packet?

• A header for assembling the packets into the correct sequence

• A footer for error checking

• A tag for high-level protocol identification

• A code for integrating into the host operating system

What is the primary purpose of the User Datagram Protocol (UDP)?

• To ensure complete data accuracy and reliability

• To provide a connectionless service focused on speed over accuracy

• To manage host addressing and routing decisions

• To encapsulate packets into datagrams for routing
