Why are gateways slower than bridges?

a- because they must read the source and destination MAC addresses


b- because they must manage sessions, translate encoded data, and interpret logical and physical addresses.


c- because they must assign new IP addresses to every packet


d- because they must interpret application programming interface output


e- because they operate at the physical layer


from net+ practice test

Why are gateways slower than bridges?
C - The fewer layers that must be processed, the lower the latency.





A gateway operates at Layer 3 of the OSI model (a bridge operates at Layer 2). A Gateway must add the IP of the next "hop" on the journey to the destination.





"A" describes Layer 2 (Data-Link)


"B" describes Layer 5 (Session)


"D" describes Layer 7 (Application)


"E" describes Layer 1 (Physical)
