Can you explain the difference between TCP and UDP protocols and when each would be used?

When it comes to networking protocols, TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two of the most commonly used ones. The main difference between TCP and UDP lies in the way they handle communication.

Focus Keyword: TCP and UDP Protocols

TCP (Transmission Control Protocol):

• Reliability: TCP is a connection-oriented protocol, ensuring reliable data delivery by establishing a connection before sending data and confirming its receipt.
• Order: TCP guarantees that data packets will arrive in the same order they were sent.
• Usage: TCP is preferred for applications that require accurate delivery of data, such as web browsing, email, and file transfers.

UDP (User Datagram Protocol):

• Speed: UDP is a connectionless protocol, making it faster than TCP because it does not have to establish a connection before sending data.
• Efficiency: UDP does not guarantee delivery or order of packets, which can lead to faster transmission but with a higher risk of data loss or duplication.
• Usage: UDP is commonly used for real-time applications like video streaming, online gaming, and VoIP services where speed is prioritized over reliability.

In summary, TCP is suited for applications that require reliable and ordered data delivery, while UDP is more suitable for applications where speed and efficiency are crucial.
