What protocol does TCP rely on?

the Internet Protocol (IP)
TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.

Does TCP require Acknowledgement?

Acknowledged data When a host requires assurance that the remote end has actually received the data it sends. But instead of requesting a signature at the remote end (computers have messy handwriting anyway), TCP requires an acknowledgement be returned.

Does TCP depend on IP?

TCP/IP is actually two separate protocols, although TCP depends on IP. The result is that TCP is able to provide the illusion that sender and receiver are connected to one another, similar to a telephone connection. However, that illusion does not include any guarantee about how quickly packets will be delivered.

What are 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.

When does a TCP send a syn to a receiving TCP?

When the sending TCP wants to establish connections, TCP sends a segment that is called a SYN to the TCP protocol on the receiving host. The receiving TCP returns a segment that is called an ACK to acknowledge the successful receipt of the segment. The sending TCP sends another ACK segment, then proceeds to send the data.

How does a process transmit data to the destination TCP?

Processes transmit data by calling on the TCP and passing buffers of data as arguments. The TCP packages the data from these buffers into segments and calls on the internet module [e.g. IP] to transmit each segment to the destination TCP. A TCP segment consists of a segment header and a data section.

How is a packet travels through the TCP / IP protocols?

each layer either add or remove fields from the basic header. When a protocol on the sending host adds data to the packet header, the process is called data encapsulation. Moreover, each layer has a different term for the altered packet, as shown in the following figure. Figure 2–1 How a Packet Travels Through the TCP/IP Stack

How does TCP allow for transmission in both directions?

TCP allows for transmission of information in both directions. This means that computer systems that communicate over TCP can send and receive data at the same time, similar to a telephone conversation. The protocol uses segments (packets) as the basic units of data transmission.
