No TCP a reliable protocol whereas UDP is unreliable.
FTP uses TCP.Usage of Transport Layer protocol (tcp or udp) depends upon various applications.Such as FTP uses TCP, TFTP uses UDP.
TCP
Server Message Block (SMB)( Explanation ) When NetBIOS is disabled, SMB runs over TCP/445. Kerberos runs on TCP/User Datagram Protocol (UDP)/88. RPC runs on TCP/135. HTTPS runs on TCP/443.
The basic protocol that allows all computers to interact on the internet is TCP/IP.
**The TCP transport layer protocol uses windowing and acknowledgments for reliable transfer of data. **The TCP and UDP port numbers are used by application layer protocols. **The TCP transport layer protocol provides services to direct the data packets to their destination hosts.
ANSWER According to W. Richard Stevens's book, TCP/IP Illustrated, Volume 1, UDP stands for User Datagram Protocol. It is unreliable, in the sense that there is no retrying defined in the protocol. This is in contrast to TCP, which stands for Transmission Control Protocol. TCP creates a connection layer on top of the unreliable Internet Protocol (IP), by retrying the transmission of sequence-numbered packets so that the receiver can correctly reconstruct the data as it was sent. UDP just transmits the packet, and if any attempt at guaranteeing that a packet was received is needed, it must be done by the application level, not at the protocol level. Note that although it seems like an application should never use an unreliable protocol, the overhead involved in creating TCP connections is often deemed unnecessary, especially for operations done on LANs (ARP, BOOTP, etc).
TCP is a sub-protocol within the IP protocol. Think of TCP as one of the instruments in a band.
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
TCP/IP is the standard default.
tcp based protocols,internet protocol,sometimes file transfer protocol also supported by tcp wrappers. tcp is reliable and connection oriented.
Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite.
No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.
A datagram socket represents a connectionless, non-guaranteed communication protocol. It represents the UDP protocol in the TCP/IP suite.Contrast this with a stream socket, which represents a connection oriented, guaranteed, communication protocol. It represents the TCP protocol in the TCP/IP suite.UDP is the underlying protocol for TCP. If you are talking OSI model, UDP is layer 3, and TCP is layer 4.
TCP
The main communication or network protocol is the TCP/IP protocol. (Transmission Control Protocol/Internet Protocol)
