The term physical topology, or network topology, mostly applies to hardware and describes how computers, other devices, and cables fit together to form the physical network. The term logical topology has to do with software and describes how access to the network is controlled, including how users and programs initially gain access to the network and how specific resources, such as applications and databases, are shared on the network.

A possible weakness of the second-chance page-replacement strategy is that if the list of pages is short, then an active page that has just moved to the back of the list after having had its referenced bit set off could quickly move to the front of the list and be selected for replacement before its referenced bit is set on. Comment on this phenomenon. Is it an anomaly in second-chance page replacement? Defend your answer carefully.
