smu mca solved answers of MCA5010 –Web Technology- Q1. Differentiate between TCP and UDP

Answer:
Transmission Control Protocol (TCP)
 Transmission Control Protocol (TCP) is a connection oriented protocol, which means the devices should open a connection before transmitting data and should close the connection gracefully after transmitting the data.
 Transmission Control Protocol (TCP) assure reliable delivery of data to the destination.
 Transmission Control Protocol (TCP) protocol provides extensive error checking mechanisms such as flow control and acknowledgment of data.
 Sequencing of data is a feature of Transmission Control Protocol (TCP).
 Delivery of data is guaranteed if you are using Transmission Control Protocol (TCP).
 Transmission Control Protocol (TCP) is comparatively slow because of these extensive error checking mechanisms
 Multiplexing and Demultiplexing is possible in Transmission Control Protocol (TCP)using TCP port numbers.
 Retransmission of lost packets is possible in Transmission Control Protocol (TCP).

User Datagram Protocol (UDP)
 User Datagram Protocol (UDP) is Datagram oriented protocol with no overhead for
opening a connection (using three-way handshake), maintaining a connection, and
closing (terminating) a connection.
 User Datagram Protocol (UDP) is efficient for broadcast/multicast type of network
transmission.
 User Datagram Protocol (UDP) has only the basic error checking mechanism using
checksums.
 There is no sequencing of data in User Datagram Protocol (UDP).
 The delivery of data cannot be guaranteed in User Datagram Protocol (UDP).
 User Datagram Protocol (UDP) is faster, simpler and more efficient than TCP. However,
User Datagram Protocol (UDP) it is less robust then TCP
 Multiplexing and Demultiplexing is possible in User Datagram Protocol (UDP) using
UDP port numbers.
 There is no retransmission of lost packets in User Datagram Protocol (UDP).
