QUESTION 26 Suppose two packets arrive to two different input ports of a router at exactly the same time. Also suppose there are no other packets anywhere in the router. Suppose the two packets are to be forwarded to the different output port. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses a crossbar? True False   QUESTION 27 UDP is a not reliable transfer protocol. True False     QUESTION 28 Circuit switching allows more utilization than packet switching  True False

Network Protocols

A network protocol is a set of rules that govern how data is exchanged between the devices in a network. Network protocols enable communication between devices that are located in different parts of the world. Consequently, they are critical in today's digital communications.
