12 Questions
What protocol is responsible for reliable, simultaneous, full duplex connection?
TCP
Which protocol is less robust than TCP and can be used by applications that do not require reliability at the Host-to-Host layer?
UDP
Which layer of the TCP/IP model is also called the Host-to-Host Layer?
Transport Layer
What does the term 'reliable' mean in the context of TCP?
TCP takes care of transmission errors by resending the portion of the data that was in error
Which layer of the TCP/IP model provides applications that use TCP and UDP?
Application Layer
Which protocol operates at the Application Layer for File Transfer?
FTP
Which layer encapsulates the data transmitted by a host in the TCP/IP model?
Application Layer
What is encapsulated by the Transport Layer Protocol in the TCP/IP model?
Application data
What happens when the encapsulated data is received by the remote host at the Receiving end?
The remote host decapsulates the header (and/or trailer) at each layer and sends the resulting data to the layer above.
Which model was first implemented, giving rise to the OSI model and TCP/IP model?
OSI model
How many layers does the OSI model have?
4 layers
Which model supports only connection-oriented communication in the Transport layer?
OSI model
Study Notes
TCP/IP Model
- TCP (Transmission Control Protocol) is responsible for a reliable, simultaneous, full duplex connection.
Protocol Comparison
- UDP (User Datagram Protocol) is less robust than TCP and can be used by applications that do not require reliability at the Host-to-Host layer.
TCP/IP Layers
- The Transport Layer is also called the Host-to-Host Layer.
TCP Reliability
- In the context of TCP, 'reliable' means ensuring that data is delivered in the correct order and retransmitting lost packets.
Application Layer
- The Application Layer provides applications that use TCP and UDP.
- FTP (File Transfer Protocol) operates at the Application Layer for file transfer.
Data Encapsulation
- The Internet Layer encapsulates the data transmitted by a host in the TCP/IP model.
- The Transport Layer Protocol encapsulates the data to be transmitted, adding a header with source and destination port numbers.
Data Reception
- When the encapsulated data is received by the remote host, the receiving end decapsulates the data, removing the headers and transporting the data to the receiving application.
Model History
- The TCP/IP model was first implemented, giving rise to the OSI model and TCP/IP model.
OSI Model
- The OSI model has 7 layers.
- The OSI model supports only connection-oriented communication in the Transport layer.
Test your knowledge about the network layer in the TCP/IP model, which is responsible for routing packets between hosts and networks, as well as implementing connections between hosts. This quiz covers the protocols and functions associated with the network layer.
