What type of protocols use a handshake process to establish the connection between devices?
Connection-oriented protocols
What is a feature of UDP (User Datagram Protocol)?
Reliable data transfer
What is the technique of collecting messages from multiple sockets at the sender's side and adding transport layer info called?
Multiplexing
Multiplexing is done by covering data messages with transport layer info, and each segment has what?
Source IP
Which layer is responsible for providing logical communication between application processes running on different hosts?
Transport layer
At the sender side, what does the transport layer do with the application messages?
Breaks them into segments then passes them to the network layer
Which protocol provides connectionless and unreliable transport at the transport layer?
UDP
What is the responsibility of the network layer?
Communication between hosts
Which feature is not a functionality of the transport layer?
Checksum for error detection
What type of transport does TCP provide at the transport layer?
Connection-oriented reliable transport
What process does the receiver side of the transport layer perform?
Reassembles received segments into messages then passes them to the application layer
Which layer is responsible for data transfer between processes?
Transport layer
What does UDP stand for in relation to its functionality at the transport layer?

This quiz covers the concepts discussed in Lecture 7 of Computer Networks, focusing on the comparison of transport layer and network layer, their respective protocols such as TCP and UDP, multiplexing/demultiplexing, and checksum. The material is based on the book 'Computer Networking: A Top Down Approach' by Jim Kurose and Keith Ross.
