They allow stations to reserve resources during the establishment of connections
In general, transport protocols can be characterized as being either connection-oriented or connectionless. Connection-oriented services must first establish a connection with the desired service before passing any data. A connectionless service can send the data without any need to establish a connection first. In general, connection-oriented services provide some level of delivery guarantee, whereas connectionless services do not. Connection-oriented service involves three phases: connection establishment, data transfer, and connection termination. During connection establishment, the end nodes may reserve resources for the connection. The end nodes also may negotiate and establish certain criteria for the transfer, such as a window size used in TCP connections. This resource reservation is one of the things exploited in some denial of service (DOS) attacks. An attacking system will send many requests for establishing a connection but then will never complete the connection. The attacked computer is then left with resources allocated for many never-completed connections. Then, when an end node tries to complete an actual connection, there are not enough resources for the valid connection. The data transfer phase occurs when the actual data is transmitted over the connection. During data transfer, most connection-oriented services will monitor for lost packets and handle resending them. The protocol is generally also responsible for putting the packets in the right sequence before passing the data up the protocol stack. When the transfer of data is complete, the end nodes terminate the connection and release resources reserved for the connection. Connection-oriented network services have more overhead than connectionless ones. Connection-oriented services must negotiate a connection, transfer data, and tear down the connection, whereas a connectionless transfer can simply send the data without the added overhead of creating and tearing down a connection. Each has its place in internetworks.
I might be wrong, but I think Enable CDP on the switch and Turn off unnecessary services.
Any country that does not have a Military or Ministry of Defense are potentially vulnerable to attacks.
Yes, ISDN (Integrated Services Digital Network) is vulnerable to security hacking. While it provides a digital connection for voice and data, its architecture lacks robust security features, making it susceptible to various attacks, such as eavesdropping and call interception. Additionally, the reliance on traditional circuit-switched technology means that ISDN can be exploited by attackers using techniques like spoofing and man-in-the-middle attacks. Organizations using ISDN should implement additional security measures to mitigate these risks.

Two ways to prevent vulnerable software attacks include using a high quality anti virus that helps detect theses attacks and only using trusted websites and software.
I felt vulnerable because the door could not be locked. The outlying parts of the empire proved vulnerable to attacks by enemies. With proper protection, a computer is vulnerable to viruses and other malware.
Because lions are stronger and much better than giraffes
because they practiced catholicism and not islam
it attacks your immune system and makes u more vulnerable to viruses.
It is a client side script essentially and they are always vulnerable to attacks. If a person can see the code then he can make changes to it both good and bad
