When answering this question, it's important to highlight the key differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Start by explaining that TCP is connection-oriented, meaning it establishes a connection before data can be sent, ensuring reliable and ordered delivery of data packets. Mention that TCP includes error-checking mechanisms and flow control, which makes it suitable for applications where data integrity is crucial, such as web browsing, email, and file transfers.
On the other hand, UDP is connectionless and does not establish a connection before sending data. It sends data packets without ensuring their delivery, making it faster but less reliable than TCP. UDP is suitable for applications where speed is more critical than reliability, such as video streaming, online gaming, and voice over IP (VoIP).
Provide examples of when each protocol would be used and emphasize the importance of choosing the right protocol based on the specific requirements of the network application. Conclude by mentioning that a good Network Engineer should understand these differences to design and manage efficient and effective networks.
