🔁TCP provides guaranteed delivery and ordered packets, while UDP focuses on speed and simplicity.
✉️TCP uses acknowledgments and retransmissions to ensure reliable delivery, while UDP does not.
😴TCP is slower than UDP due to the additional features it offers for reliability and ordering.
🧩TCP is connection-based and maintains state, while UDP is stateless and connectionless.
🛡️TCP is more susceptible to denial-of-service attacks due to its connection-based nature.
What is the main difference between TCP and UDP?
—The main difference is that TCP provides reliable delivery and ordering of packets, while UDP does not.
When should I use TCP?
—TCP is recommended for applications that require guaranteed delivery and ordered packets, such as file transfer and web browsing.
When should I use UDP?
—UDP is suitable for applications that prioritize speed over reliability, such as video streaming and online gaming.
Can UDP be as reliable as TCP?
—UDP does not provide the same level of reliability as TCP, as it does not guarantee delivery or order of packets.
Can TCP be as fast as UDP?
—TCP is generally slower than UDP due to the additional features it offers for reliability and ordering of packets.
