        **What is Connection-oriented communication?**

        A connection-oriented protocol like TCP ensures a reliable communication path is established between two devices before transmitting data. It maintains the connection throughout the session.

        **Why is Connection-oriented communication useful?**

        Connection-oriented communication is useful because it guarantees that data is delivered accurately, in order, and without duplication. This is essential for services like web browsing, file transfers, and email.

        **How does Connection-oriented communication work?**

        A connection-oriented protocol like TCP starts with a three-way handshake to establish a connection. Data is then exchanged reliably using acknowledgments and retransmissions. Once the session is over, the connection is properly closed.

        **Where is Connection-oriented communication used?**

        Connection-oriented communication is used in applications where reliability matters — such as web servers (HTTP/HTTPS), file transfers (FTP), emails (SMTP, IMAP), and remote logins (SSH).

        **Which OSI layer does Connection-oriented communication belong to?**

        Connection-oriented protocols like TCP operate at the **Transport Layer (Layer 4)** of the OSI model.

        **Is Connection-oriented communication Windows specific?**

        No, connection-oriented communication is not specific to Windows. TCP is implemented on all major platforms including Linux, macOS, and embedded systems.

        **Is Connection-oriented communication Linux specific?**

        No, TCP (as a connection-oriented protocol) is supported universally across all operating systems and is a core part of the internet protocol suite.

        **Which Transport Protocol is used by Connection-oriented communication?**

        The primary transport protocol used for connection-oriented communication is **TCP (Transmission Control Protocol)**.

        **Is Connection-oriented communication using client-server model?**

        Yes, connection-oriented protocols are commonly used in client-server models. A client initiates the connection, and the server manages and responds reliably throughout the session.
