<p>TCP = Connection-oriented and provides reliable delivery UDP = Connectionless and provides unreliable delivery DHCP = Connectionless protocol for automated configuration of IP address TFTP = Connectionless protocol for trivial file transfer</p> Signup and view all the answers

<p>Non-ephemeral = Permanent port numbers, usually on a server or service Ephemeral = Temporary port numbers, determined in real-time by the client Server port = IP address, protocol, and server application port number Client port = IP address, protocol, and client port number</p> Signup and view all the answers

<p>TCP = Commonly used for server to server email transfer UDP = Used for real-time communication where data cannot be stopped and resent HTTPS = Connection-oriented protocol that prefers a 'return receipt' and is commonly used for secure communication SSH = Connection-oriented protocol that prefers a 'return receipt' and is commonly used for remote login to devices</p> Signup and view all the answers

<p>IP address = Unique identifier for a device on a network Port = Written on the outside of the box and represents a specific destination on a device Connectionless = No formal open/close to the connection Connection-oriented = Involves a formal connection setup and close</p> Signup and view all the answers

<p>TCP = Provides 'reliable' delivery with recovery from errors and can manage out-of-order messages or retransmissions UDP = Provides 'unreliable' delivery with no error recovery or reordering of data</p> Signup and view all the answers
