What characterizes an end-to-end connection in networking?

An end-to-end connection in networking is characterized by a direct communication path established between the source and destination devices. This means that the data travels directly from the initiating device to the receiving device without the need for intermediaries, ensuring that the communication is efficient and straightforward.

This type of connection is essential for various applications that require a reliable and continuous stream of data, such as video conferencing or real-time online gaming. The absence of intermediate servers means that latency can be minimized, and the data can be transmitted quickly and securely directly from one point to another.

The other options describe different scenarios that don't fulfill the criteria of an end-to-end connection. Intermediate servers, temporary connections, and wireless connections do not inherently represent the fundamental nature of end-to-end communication as they introduce varying degrees of complexity and potential inefficiencies or limitations.
