Which 2 protocols are used in the transport layer of the TCP IP model?
Sarah Smith
Published Jan 13, 2026
The two most important protocols in the Transport Layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP provides reliable data delivery service with end-to-end error detection and correction. UDP provides low-overhead, connectionless datagram delivery service.
Which 2 protocols are used in the transport layer of the TCP IP model UDP and HTTP TCP and UDP HTTP and TCP ICMP and HTTP?
The two protocols used in the transport layer are User Datagram protocol and Transmission control protocol.
Which 2 protocols are used in the transport?
In the IP protocol stack, the most widely used two transport protocols are User Datagram Protocol (UDP) and the Transport Control Protocol (TCP).
What is transport layer in TCP IP model?
The transport layer is responsible for error-free, end-to-end delivery of data from the source host to the destination host. It corresponds to the transport layer of the OSI model. The functions of the transport layer are − It facilitates the communicating hosts to carry on a conversation.
What is transport layer in TCP IP?
The transport layer provides a total end-to-end solution for reliable communications. TCP/IP relies on the transport layer to effectively control communications between two hosts. When an IP communication session must begin or end, the transport layer is used to build this connection.

The transport layer also provides the acknowledgement of the successful data transmission and sends the next data if no errors occurred. Typical examples of layer 4 are the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
What is TCP and UDP protocols?
TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
Which protocol uses both TCP and UDP?
For example, DNS uses both TCP and UDP for valid reasons described below. UDP messages aren't larger than 512 Bytes and are truncated when greater than this size. DNS uses TCP for Zone transfer and UDP for name, and queries either regular (primary) or reverse.
Which of the following protocols uses both TCP and?
Which of the following protocols uses both TCP and UDP? Explanation: DNS and some other services work on both TCP and the UDP protocols. DNS uses TCP for zone exchanges between servers and UDP when a client is trying to resolve a hostname to an IP address.
Which of the protocols below uses TCP at the Transport layer?
HTTPS Explanation- Smtp, ftp, http, https all use TCP at the transport layer because of the reliable...
Which of the following uses TCP as the transport protocol?
Explanation: SMTP, HTTP and FTP use TCP.
Which of the following transport layer protocols are used in networking?
Which of the following are transport layer protocols used in networking? Explanation: Both TCP and UDP are transport layer protocol in networking. TCP is an abbreviation for Transmission Control Protocol and UDP is an abbreviation for User Datagram Protocol. TCP is connection oriented whereas UDP is connectionless.
Which protocol is best example of transport layer?
The best-known transport protocol of the Internet protocol suite is the Transmission Control Protocol (TCP).
What protocols use UDP?
Numerous key Internet applications use UDP, including: the Domain Name System (DNS), the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP). Voice and video traffic is generally transmitted using UDP.
What are the two transport protocols offered by the Internet and what are their main characteristics?
There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol.
Why TCP and UDP are both required in transport layer?
Differences between the TCP and UDP. Both the protocols, i.e., TCP and UDP, are the transport layer protocol. TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. It means that TCP requires connection prior to the communication, but the UDP does not require any connection.
Which of the following protocols are examples of TCP IP transport layer protocols?
Which of the following protocols are examples of TCP/IP transport layer protocols? (Choose two answers.) D (UDP) and F (TCP).
Is FTP a transport layer protocol?
FTP itself uses the TCP transport protocol exclusively, or in other words, it never uses UDP for its transport needs. Typically an application layer protocol will use one or the other. One notable exception to that is DNS or Domain Name System. FTP also is odd in the fact that it uses two ports to accomplish its task.
Which of the following transport layer protocols is used to support electronic?
Which of the following transport layer protocols is used to support electronic mail? Explanation: E-mail uses SMTP as application layer protocol.
Which two application layer protocols use UDP choose two?
DHCP, SNMP, and TFTP use UDP.
How many protocols are used in the application layer *?
4. How many protocols are used in the application layer? Explanation: More than 15 protocols are used in the application layer, including file transfer protocol, Telnet, Trivial File Transfer Protocol and simple network Management Protocol.
Which of the following protocols use TCP select all that apply?
Explanation: SMTP, HTTP and FTP use TCP.
Which 2 of the following network protocols do not use TCP?
Answer: The most common alternative is UDP ( user datagram protocol ). UDP is designed for applications where you don't need to put sequences of packets together. It fits into the system much like TCP.
