What decides TCP or UDP?
TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.
Why do you think TCP was chosen for HTTP and not UDP?
Since TCP is connection-oriented, it ensures that there is no congestion on the data channel that’s been setup. UDP is connectionless and doesn’t care much about congestion. Each packet is sent separately and if a packet is lost due to congestion, the recipient can’t do much about it.
What are the two most commonly used Internet transport protocol?
The most common transport protocols are TCP and UDP.
What are two protocols on the transport layer and how do they differ?
TCP and UDP are both transport layer protocols. TCP is a connection orientated protocol and provides reliable message transfer. UDP is a connection less protocol and does not guarantee message delivery.

| Feature | TCP | UDP |
|---|---|---|
| Speed | Slower than UDP | Faster than TCP |
| Broadcasting | Does not support Broadcasting | Does support Broadcasting |
| Optimal use | Used by HTTPS, HTTP, SMTP, POP, FTP, etc | Video conferencing, streaming, DNS, VoIP, etc |
How does TCP differ from UDP choose two?
TCP differs from UDP in the following ways: TCP provides best effort delivery. TCP provides synchronized communication. TCP segments are essentially datagrams.
What two situations would UDP be better than TCP as the preferred transport protocol choose two?
In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)
- when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated.
- when a faster delivery mechanism is needed.
- when delivery overhead is not an issue.
Is HTTP over TCP or UDP?
HTTP and connections Among the two most common transport protocols on the Internet, TCP is reliable and UDP isn’t. HTTP therefore relies on the TCP standard, which is connection-based.
What determines the choice of transport protocol?
Choosing the right protocol for data transport depends on the needs of the application and the nature of the data. Most applications use a standard network transport protocol: either TCP or UDP. However these default choices do not satisfy strategic applications that use time-critical data.
What is transport layer responsible for?
Transport Layer responsibilities
- Process to process delivery –
- End-to-end Connection between hosts –
- Multiplexing and Demultiplexing –
- Congestion Control –
- Data integrity and Error correction –
- Flow control –
Who uses UDP?
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.
Which one of the following is transport layer protocol?
The correct answer is option 3, i.e. UDP. The main role of Transport Layer is to provide communication services directly to the application processes running in different hosts. It consists of two protocol i.e. TCP and UDP.
Which two protocols display the transport layer?
Two protocols display the transport layer. 1. UDP 2. TCP What is UDP? The full form of UDP is User Datagram Protocol. It is a connectionless protocol. UDP is a transport-level end-to-end protocol that adds addresses of transport-level, control of errors in the checksum, and data lengths from the top laying.
What is the purpose of the UDP protocol?
Transport Layer protocols 1 UDP stands for User Datagram Protocol. 2 UDP is a simple protocol and it provides nonsequenced transport functionality. 3 UDP is a connectionless protocol. 4 This type of protocol is used when reliability and security are less important than speed and size.
What is the difference between TCP and UDP and HTTP?
It is used by application protocols like HTTP and FTP. UDP is also a layer 4 protocol but unlike TCP it doesn’t provide acknowledgement of the sent packets. Therefore, it isn’t reliable and depends on the higher layer protocols for the same.
What type of data is transferred by TCP?
Stream data transfer: TCP protocol transfers the data in the form of contiguous stream of bytes. TCP group the bytes in the form of TCP segments and then passed it to the IP layer for transmission to the destination. TCP itself segments the data and forward to the IP.
