What is usually used to acknowledge that data was received and to request the retransmission of missing data?
upper layer connection oriented protocols
Is DNS connectionless or connection-oriented?
DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
What type of protocol is useful when data must be transferred quickly?
Connectionless protocols
List 3 protocols implemented at the network layer that carry user data?
The network layer is the third level of the Open Systems Interconnection or the OSI model. The protocols that are implemented at this layer which carry user data include: Internet Protocol version 4 (IPv4), Internet Protocol version 6 (IPv6) and Novell Internetwork Packet Exchange (IPX).
The data link layer handles transmission errors by requesting damaged frames to be?
Damaged frames are discarded. Retransmission - if needed - is handled by higher-layer protocols, like TCP.

When connectionless protocols are implemented at the lower layers of the OSI model?
an upper-layer, connection-oriented protocol or service
What protocols are connectionless?
UDP

What protocols do not guarantee delivery of their data but do operate with a very low overhead that conserves network bandwidth?
connectionless protocols - transport layer
Which class of connection mode transport protocols has feature of retransmission on timeout?
To 3
What type of protocol is useful when data must be transferred quickly?
Connectionless protocols
The TCP IP suite of protocols is implemented by?
TCP/IP protocols are implemented by software, except for the bottom physical layer, which is implemented in hardware.
Transport layer protocols that do not establish a connection before transmission and make no effort to ensure that data is delivered error-free are called?
connectionless protocols
What is a connectionless?
Connectionless Protocols: These protocols do not establish a connection between devices. As soon as a device has data to send to another, it just sends it. Answer:A Connectionless Protocol is a data communication method in which communication occurs between hosts with no previous setup. The device at one end of the communication transmits data to the other, without first ensuring that the recipient is available and ready to receive the data. The device sending a message simply sends it addressed to the intended recipient. The internet Protocol (IP) and User Datagram Protocol (UDP) are connectionless protocols, but TCP/IP (the most common use of IP) is connection-oriented
Which protocol working at the Transport layer provides a connectionless service between hosts?
There are many connectionless protocols depending on which layer of the OSI model you are referring to. An example would be UDP for transport, and IP for routing.
