Question: What is TCP and UDP?

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.

What is TCP and UDP with example?

TCP - used for traffic that you need all the data for. i.e HTML, pictures, etc. UDP - used for traffic that doesnt suffer much if a packet is dropped, i.e. video & voice streaming, some data channels of online games, etc.

What is TCP and UDP protocols?

TCP is a connection-oriented communication protocol. UDP is a connectionless communication protocol. TCP rearranges data packets to be received in their intended order. UDP sends datagrams independently, meaning that they may arrive in a different order. Uses a three-way handshake to establish reliable connections.

What is TCP and UDP port?

TCP is a connection orientated protocol and provides reliable message transfer. UDP is a connection less protocol and does not guarantee message delivery. The choice of TCP vs UDP is made by the application developer in accordance with the application connection requirements. References: List of Assigned Ports.

What is TCP and UDP full form?

Transmission control protocol (TCP) User datagram protocol (UDP) TCP is a connection-oriented protocol. Connection-orientation means that the communicating devices should establish a connection before transmitting data and should close the connection after transmitting the data. UDP is the Datagram oriented protocol.

Does Netflix use UDP?

Netflix, Hulu, Youtube, etc. video streaming all use TCP and simply buffer a few seconds of content, instead of using UDP since the delay is not crucial and TCP transfers can be easily accomplished over HTTP and web browsers without the need for additional plugins and software.

Does UDP use IP?

UDP uses IP to get a datagram from one computer to another. UDP works by gathering data in a UDP packet and adding its own header information to the packet. This data consists of the source and destination ports on which to communicate, the packet length and a checksum.

Does Netflix use TCP or UDP?

Both Amazon Prime and Netflix use TCP as the transport layer protocol. YouTube on the other hand use both UDP and TCP protocols.

Is UDP secure?

The big security problem with UDP is that you are susceptible to spoofing and DOS attacks. Its not possible to spoof an address across the internet using TCP since the handshake will never complete. OTOH with UDP there is no implicit handshake - any session maintenance must be done by your code (processing overhead).

Is YouTube a UDP?

YouTube on the other hand use both UDP and TCP protocols. Since Amazon Prime is running on AWS, HTTP/2 is the protocol used by it. YouTube UDP uses QUIC. Netflix uses HTTP 1.1 and not HTTP/2.

Is UDP used today?

Numerous key Internet applications use UDP, including: the Domain Name System (DNS), where queries must be fast and only consist of a single request followed by a single reply packet, the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP) ...

Is Youtube a TCP or UDP?

Netflix, Hulu, Youtube, etc. video streaming all use TCP and simply buffer a few seconds of content, instead of using UDP since the delay is not crucial and TCP transfers can be easily accomplished over HTTP and web browsers without the need for additional plugins and software.

Is FTP UDP or TCP?

FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a data port and a command port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.

What is UDP good for?

UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.

What is UDP port 443 used for?

Side note: UDP port 443 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 443 makes possible the transmission of a datagram message from one computer to an application running in another computer.

Is port 80 A TCP?

Port 80 is one of the most commonly used port numbers in the Transmission Control Protocol (TCP) suite. Any Web/HTTP client, such as a Web browser, uses port 80 to send and receive requested Web pages from a HTTP server.
