A. Hyper text transfer protocol
B. Real-time transport control protocol
C. User datagram protocol
D. Transport control protocol
Explanation: TCP can work well because it is robust and helps the packets to be delivered safely and quickly and it does not cause congestion. TCP was defined in RFC 793 and it has improved in a way that it can adapt the attributes of internet and deals with errors well.
A. Sctp and HTTP
B. SMTP and HTTP
C. Tcp and udp
D. Tcp and sctp
Explanation: TCP and SCTP are connection oriented protocols and they ensure that there is no packet loss. Also, these protocols use different methods and mechanisms such as flow control, error control, congestion control and acknowledgments to achieve reliability.
A. Flow control
B. Error control
C. Sequencing
D. Acknowledgement
Explanation: Senders may send the data at a rate that can not be handled by a receiver and may drench the receiver with load. In such scenarios, flow control mechanism informs the receiver to decrease the rate at which it is sending. If the rate is very slow, then the sender will be asked to increase the rate.
A. Udp
B. Tcp
C. Sctp
D. Udp and tcp
Explanation: TCP supports uni-casting transmission, where only one receiver and one sender will be present and it requires source and destination IP addresses only. Multi-casting is another version of transmission in which more than one receiver can be present.
A. Udp
B. Tcp
C. Sctp
D. HTTP
Explanation: Stream control transmission protocol provides the facility to transmit multiple streams for a single connection. That is, a single connection can have multiple ways and block of one way(path) does not affect other streams.
A. Connection establishment ? connection termination ? data transfer
B. Connection establishment ? data transfer ? connection termination
C. Data transfer ? connection establishment ? connection termination
D. Data transfer ? connection termination ? connection establishment
Explanation: Primarily, the sender sends the request to a receiver in order to establish a connection; if the receiver accepts the request, then the data transfer takes place. After the transmission, connection is terminated.
A. Multi-casting
B. Connection-oriented service
C. Full duplex communication
D. Reliable service
Explanation: Multi-casting has more than one receiver host for a stream of data that is sent by a process and it maintains a group. But TCP supports uni-casting, in which one sender will have only one receiver. Broadcasting is also not supported by TCP.
A. Process-to-process protocol
B. Connection-oriented protocol
C. Does error checking
D. Uses port numbers
Explanation: The major difference between TCP and UDP is connection, UDP is connection less protocol whereas TCP is connection oriented. UDP facilitates the application’s process to send the datagrams without building a connection between the two processes.
A. True
B. False
C.
D.
Explanation: Transport layer deals with processes that are running on different hosts, hence reliability is achieved between processes. A single host can have multiple processes running in it with different port numbers. Reliability between hosts can be achieved by data link layer.
