TCP and UDP are both protocols used for communication over the internet.
TCP, which stands for Transmission Control Protocol, is a connection-oriented protocol. This means that before data is transmitted, a connection is established between the sender and receiver. TCP ensures that all data packets are received in the correct order and without errors. It also provides flow control, which means that it regulates the rate at which data is sent to prevent overwhelming the receiver.
UDP, on the other hand, stands for User Datagram Protocol. It is a connectionless protocol, which means that data is sent without establishing a connection first. UDP is faster and more efficient than TCP, but it does not provide the same level of reliability. Unlike TCP, UDP does not guarantee that all data packets will be received or that they will be received in the correct order.
Both TCP and UDP are used for different purposes. TCP is commonly used for applications that require reliable and ordered delivery of data, such as web browsing and file transfer. UDP is used for applications that require fast and efficient delivery, such as streaming media and online gaming.
The choice between TCP and UDP depends on the specific requirements of the application.
