💡 Hint

Common Mistakes

Assuming UDP guarantees delivery like TCP does.

UDP is preferred for gaming because it allows fast transmission with low delay, even though it does not guarantee delivery of all packets.

💡 Hint

Common Mistakes

Choosing 'increases' which is incorrect for UDP's behavior.

UDP is used in streaming because it reduces the overhead of establishing a connection, allowing faster data transmission.

5fill in blank

Fill all three blanks to describe UDP use in gaming.

Computer Networks

In online gaming, UDP is used because it [1] latency, [2] packet loss, and [3] connection setup time.

💡 Hint

Common Mistakes

Selecting 'increases' which is opposite of UDP's effect on latency.

UDP reduces latency, tolerates some packet loss, and avoids connection setup time, making it suitable for fast-paced online gaming.
