<p>Application layer = Includes the protocols used by most applications for providing user services or exchanging application data over the network connections established by the lower-level protocols Transport layer = Provides reliable or unreliable data delivery services to the upper layers Internet layer = Responsible for moving packets between the internet layer interfaces of two different hosts on the same link Link layer = Establishes basic data channels that applications use for task-specific data exchange</p> Signup and view all the answers

<p>TCP = A connection-oriented protocol that provides a reliable byte stream UDP = A connectionless datagram protocol that is best-effort and unreliable SCTP = A newer protocol that is message-stream-oriented and provides multiple streams multiplexed over a single connection QUIC = An emerging alternative transport protocol that is technically carried via UDP packets and seeks to offer enhanced transport connectivity relative to TCP</p> Signup and view all the answers

<p>HTTP = A protocol for transferring hypertext requests and responses between clients and servers FTP = A protocol used for transferring files between a client and server on a computer network SMTP = A protocol for sending and receiving electronic mail DHCP = A protocol that automatically assigns IP addresses to devices on a network</p> Signup and view all the answers

<p>TCP = High reliability, as it provides a reliable byte stream UDP = No reliability, as it is a best-effort, unreliable protocol SCTP = High reliability, as it is also a reliable, connection-oriented transport mechanism QUIC = Enhanced reliability relative to TCP, as it seeks to offer enhanced transport connectivity</p> Signup and view all the answers

<p>Link layer = Operates within the scope of the local network connection to which a host is attached Internet layer = Responsible for sending data from the source network to the destination network Transport layer = Establishes basic data channels that applications use for task-specific data exchange Application layer = Includes the protocols used by most applications for providing user services or exchanging application data over the network connections established by the lower-level protocols</p> Signup and view all the answers
