TCP ensures that the data reaches intended destination in the same order it was sent. … TCP requires that connection between two remote points be established before sending actual data. TCP provides error-checking and recovery mechanism. TCP provides end-to-end communication.
What is TCP transmission policy?
TCP is a reliable stream delivery service which guarantees that all bytes received will be identical and in the same order as those sent. Since packet transfer by many networks is not reliable, TCP achieves this using a technique known as positive acknowledgement with re-transmission.
What is the role of TCP in data transmission?
The Transmission Control Protocol (TCP) is a transport protocol that is used on top of IP to ensure reliable transmission of packets. TCP includes mechanisms to solve many of the problems that arise from packet-based messaging, such as lost packets, out of order packets, duplicate packets, and corrupted packets.
What are key characteristics of the transmission control protocol TCP?
Key Concept: To summarize TCP's key characteristics, we can say that it is connection-oriented, bidirectional, multiply-connected, reliable, acknowledged, stream-oriented and flow-managed.
What factors make TCP reliable?
TCP must recover data that is damaged, lost, duplicated, or delivered out of order by the Internet. TCP achieves this reliability by assigning a sequence number to each octet it transmits and requiring a positive acknowledgment (ACK) from the receiving TCP.
What is AIMD algorithm?
The additive-increase/multiplicative-decrease (AIMD) algorithm is a feedback control algorithm best known for its use in TCP congestion control. AIMD combines linear growth of the congestion window when there is no congestion with an exponential reduction when congestion is detected.
What is difference between HTTP and TCP?
HTTP is faster in comparison to TCP as it operates at a higher speed and performs the process immediately. TCP is relatively slower. … TCP manages the data stream, whereas HTTP describes what the data in the stream contains. TCP operates as a three-way communication protocol, while HTTP is a single-way protocol.
Which communication is offered by TCP?
Explanation: data can flow both the directions at the same time during a tcp communication hence, it is full-duplex. this is the reason why tcp is used in systems that require full-duplex operation such as e-mail systems.
