Both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) operate at the Transport Layer (Layer 4) of the OSI model. These protocols are responsible for managing the end-to-end communication and flow of data between devices on a network.
A). TCP (Transmission Control Protocol): TCP is a connection-oriented protocol that provides reliable, ordered, and error-checked delivery of data between applications. It ensures that data packets are delivered correctly and in the correct order.
B). UDP (User Datagram Protocol): UDP is a connectionless protocol that does not guarantee reliable delivery or ordering of data packets. It is used in applications where speed is more important than reliability, such as streaming media or online gaming.
