Aconnection-oriented protocol in a packet-switched network guarantees a dedicated line - similar to how a circuit-switched network works?

False

Explanation:

Circuit and packet switching refers to systems through which information or data is transmitted, only that great features in circuit switching are a dedicated channel

The packet switching data or information that is transmitted is previously assembled into packets. Each of the packages is transmitted individually and will be able to follow different routes to reach the destination. As soon as they do, those packages are re-assembled.

Packet switching is more efficient than circuit switching and is also more robust for data that can be sent with transmission delay, that is, it is not real-time, such as on a web page, email, files.

Circuit switching is a type of communication which is established or created through a dedicated channel that is known as a circuit, the duration of a session. As soon as that session is finished (such as a telephone call), the channel will be released and therefore can be used by another pair of users.
