Which protocol ensures reliable delivery

Which protocol ensures reliable delivery at transport layer?

UDP
TCP
IP
None of these

Answer: TCP

Which protocol is reliable delivery?

TCP protocol gives thorough guarantee to deliver packets of data through reliable channels. Plus information will be delivered in the same order as it is sent. 

Which protocol ensures reliable delivery and data recovery?

TCP is known to be the best reliable source when it comes to delivering data securely and in the same order. 

How does TCP ensure reliable delivery?

• It ensures to send data to the same application layer and in the same sequence.
• TCP ensures flow control and it does not overwhelm the receiver end.
• In case of any issue during transfer of data, packets are re-transferred again. 
• TCP allows multiple applications to access transmission networks at the same time.

What technique does TCP use to ensure segments are delivered in the correct order?

TCP is able to break the received information or data into small packets known as segments. For the sake of reliable transmission, TCP allocates numbers to segments before passing them to IP procedure. 

Which protocol is used in transport layer?

UDP and TCP protocols are used in transport layers.

Which protocol is used for real time communication?

IRC(Internet Relay Chat) is a protocol used for real time communication.

Is TCP faster than UDP?

NO, TCP is not faster than UDP

Which protocol uses both TCP and UDP?

SNMP and DNS protocols are using UDP and TCP.

What is TCP vs UDP?

TCP is a connection oriented protocol which ensures the delivery of information and in case of any issue, it retransmits the data. 
Whereas UDP protocol follows connectionless approach. It transmits data quickly but does not have any mechanism to retransmit the data. 

Is TCP reliable or unreliable?

TCP is reliable as compared to any other protocol as it keeps track of the transmitted data and makes sure that information is not corrupted as well.

Why TCP and IP are used together?

TCP and IP layer lets you determine how a particular machine should connect to the internet and how the data will be transferred in between the sender and receiver. TCP/IP layers are used over a large distance communication. 

What is reliable stream delivery?

It works on closing a TCP connection. Once there remains no more information to be transmitted, TCP immediately disables the connection in one direction. Then it waits for the acknowledgement from receiving end and transmits data with FIN bit set.

Is TCP lossless?

Yes, TCP operates in lossless manner, means your data will never lost and it will be sent in same sequence as it receives.

Which protocol does not provide reliable end to end communication?

Both TCP and UDP
Neither TCP nor UDP
UDP
TCP

Answer: TCP

Which of the following is false with respect to TCP?

Unreliable 
Process-to-process
Unreliable
Connection-oriented 

Answer: Unreliable 

UDP is a protocol?

This protocol is offering data transmission services the same like TCP protocol. It follows a reassembly and segmentation approach. But it is not able to provide flow control and reliable transmission of data.
