Welcome to Networking Quiz, Entry Level !!

Question 1. The Internet Control Message Protocol (ICMP)

allows gateways to send error a control messages to other gateways or hosts

provides communication between the Internet Protocol Software on one machine and the Internet Protocol Software on another

only reports error conditions to the original source, the source must relate errors to individual application programs and take action to correct the problem

All of the above

simplex

duplex

multiplex

half-duplex

network

application

data-link

session

Question 4. contention is ?
