Explain application transport method in brief.
Application transport methods refer to the mechanisms used to facilitate the exchange of data between different software applications over a network. These methods ensure that data is transferred reliably and efficiently, regardless of the underlying network infrastructure.
One common application transport method is the Transmission Control Protocol (TCP), which provides reliable, connection-oriented communication between applications. TCP ensures that data is delivered in the correct order and without errors by employing mechanisms such as acknowledgment and retransmission.
Another widely used application transport method is the User Datagram Protocol (UDP). Unlike TCP, UDP is connectionless and does not guarantee reliable delivery or ordered data transmission. However, UDP is often preferred for applications where real-time communication or low overhead is more important than reliability, such as streaming media or online gaming.
