Tcp Ip Protocol Questions
The Transmission Control Protocol (TCP) is one of the core protocols in the TCP/IP Protocol suite. It provides reliable, connection-oriented communication between devices over an IP network. Some of the key features of TCP are:
1. Reliability: TCP ensures reliable delivery of data by using acknowledgments and retransmissions. It guarantees that data sent from one device is received correctly by the destination device.
2. Connection-oriented: TCP establishes a connection between the sender and receiver before data transmission. This connection is maintained until the communication is complete, ensuring ordered and error-free delivery of data.
3. Flow control: TCP implements flow control mechanisms to prevent overwhelming the receiver with more data than it can handle. It uses a sliding window technique to regulate the amount of data sent at a time, based on the receiver's capacity.
4. Congestion control: TCP employs congestion control algorithms to prevent network congestion. It dynamically adjusts the transmission rate based on network conditions, ensuring fair sharing of network resources and avoiding network congestion.
5. Multiplexing and demultiplexing: TCP supports the multiplexing and demultiplexing of multiple applications running on the same device. It uses port numbers to identify different applications and ensures that data is correctly delivered to the intended application.
6. Full-duplex communication: TCP allows simultaneous bidirectional communication between devices. It supports both sending and receiving data at the same time, enabling efficient and interactive communication.
7. Error detection and recovery: TCP includes error detection mechanisms to identify corrupted or lost data during transmission. It uses checksums to verify data integrity and retransmits lost or damaged packets to ensure reliable delivery.
Overall, TCP provides a robust and reliable communication channel, making it suitable for applications that require guaranteed delivery of data, such as web browsing, email, file transfer, and real-time streaming.
