1. TCP is connectionless. This statement is false. TCP (Transmission Control Protocol) is a connection-oriented protocol. It establishes a connection between the sender and receiver before data transfer and maintains that connection until the communication is terminated. This ensures reliable and ordered delivery of data.
2. TCP provides guaranteed delivery of data. True. TCP provides reliable delivery of data between applications running on hosts communicating over an IP network. It uses acknowledgments, sequence numbers, and timeouts to ensure data is delivered correctly and in order.
3. TCP operates on the transport layer of the OSI model. True. TCP operates at the transport layer, layer 4 in the Open Systems Interconnection (OSI) model. This layer is responsible for providing host-to-host communication services for applications.
4. TCP headers do not include a checksum. False. TCP headers include a checksum field. The checksum helps ensure that data is transmitted without errors over the network. It is used to detect data corruption in the transmitted segments.
5. TCP is used for streaming media and real-time applications. Generally False. While TCP can be used for a wide range of applications, streaming media and real-time applications (like VOIP or online gaming) often prefer UDP (User Datagram Protocol) over TCP. UDP is a connectionless protocol that reduces delay and overhead by not requiring acknowledgment or retransmission of packets, making it better suited for real-time applications where timely delivery is more important than perfectly
