_____________ communication is a form of communication in which the sending system does not “introduce” itself—it just fires the data off. Also, the destination computer does not notify the source when the information is received. This type of communication can be unreliable because there is no notification to guarantee delivery. It can be faster than the other type of communication because the overhead of managing the session is not there, and after the information is sent, there is no second step to ensure proper receipt of information.
Explanation
Connectionless communication is a form of communication where the sending system does not identify itself and simply transmits the data without any acknowledgment from the destination computer. This type of communication can be unreliable as there is no guarantee of delivery. However, it can be faster than connection-oriented communication because there is no overhead of managing the session and no need for a second step to ensure proper receipt of information. Therefore, the correct answer is "Connectionless."
