Here's what you need to know about UDP in CCNA:
* It's a connectionless protocol: Unlike TCP, UDP doesn't establish a connection before sending data. This makes it faster but less reliable.
* It's used for time-sensitive applications: Games, video streaming, and VoIP rely on UDP's speed.
* It's less reliable than TCP: UDP doesn't guarantee that data will arrive in order or at all. Packets can be lost, duplicated, or arrive out of sequence.
* It's often used in conjunction with other protocols: Applications like DNS (Domain Name System) and DHCP (Dynamic Host Configuration Protocol) use UDP.
In CCNA, you'll learn about:
* The differences between UDP and TCP: Understanding when to use each protocol is essential.
* How UDP packets are structured: This helps you understand how data is encapsulated and transmitted.
* The limitations of UDP: You'll learn about packet loss and how to address it in certain applications.
