UDP
For example, you send a message through a bottle with a message to the sea. UDP is similar: it sends data without any guarantee of delivery or confirmation that it was received.

How UDP protocol works:

Sending data in "packets" When you send data over UDP, it is broken into small pieces called packets, just as if you were putting each word of your message in a separate bottle.
Send without confirmation. Packets are sent to their addresses, but china email list the sender does not receive any confirmation back that they were successfully delivered. This means that if a packet gets lost along the way, the sender will not know about it.
Fast and efficient. UDP is faster than TCP because it doesn't waste time waiting for acknowledgements or resending lost data. It just sends the data and hopes it gets there.
UDP is often used to transmit data where small delays are more important than guaranteed delivery, such as when transmitting real-time audio and video data (e.g. video calls or streaming video).


SIP
SIP (Session Initiation Protocol) is a protocol used to establish and manage communications over the Internet, including voice and video calls, messaging, and other forms of communication.

Imagine calling someone on the phone. SIP is like a system that helps you dial and connect to another person. It defines how your device establishes and terminates connections with other devices over the Internet.

The SIP protocol allows devices to exchange information about how they can communicate with each other (such as IP addresses) and what communication features they support (such as voice calls, video calls, messaging). This makes SIP a key element in the implementation of digital telephony and other forms of communication over the Internet.


LAN
A local area network (LAN) is a network that connects computers and other devices within a single location, such as a home, office, or school. It is like a small, closed community where all devices can communicate with each other directly, without having to go out into the outside world. A LAN is often used for sharing files, printing documents, playing online games, and other tasks that require communication between devices within a single location.

The Internet, on the other hand, is a global network that connects many local networks around the world. It is like a huge network that connects all corners of the earth. With the help of the Internet, people can exchange information, communicate, search for information, watch videos, buy products and much more. It allows you to connect to any device or resource anywhere in the world, as long as you have access to the network.
