10 Questions
What is the main responsibility of the transport layer in a computer network?
Providing logical communication between application processes on different hosts
Which functionality is NOT a responsibility of the transport layer in a computer network?
Routing packets between hosts
Which transport layer protocol provides connection-oriented and reliable transport?
TCP
What function does UDP perform in a computer network?
Connectionless/unreliable transport
What communication does the network layer in a computer network facilitate?
Communication between hosts
What is the main difference between connection-oriented protocols and connectionless protocols?
Connection-oriented protocols establish a dedicated connection between devices before transmitting data, while connectionless protocols don’t establish a dedicated connection before transmitting data.
What feature is unique to TCP (Transmission Control Protocol) and not available in UDP (User Datagram Protocol)?
Congestion control
What is the purpose of multiplexing at the sender's side in the transport layer?
To collect messages from multiple sockets and add transport layer info for demultiplexing
What type of protocol ensures that all data packets are delivered without any errors?
Connection-oriented protocol
Which service is not available in both UDP and TCP?
Determined delay guarantees
This quiz covers the content from Lecture 7 of Computer Networks, focusing on the comparison between transport layer and network layer, their protocols (TCP and UDP), multiplexing/demultiplexing, and checksum. The content is based on the book 'Computer Networking: A Top Down Approach' by Jim Kurose and Keith Ross, 6th edition.
