Hub-based network In large networks of this type, new problems can arise Late collisions occur when two stations successfully test for a clear network, and then transmit, only to then encounter a collision This condition can occur when the network is so large that the propagation of a transmitted frame from one end of the network to the other takes longer than the test used to detect whether the network. .. For our purposes, we will define these network types as follows: Local Area Network (LAN) A LAN is a network that is confined to a limited space, such as a building or floor It uses short-range technologies such as Ethernet, Token Ring, and the like A LAN is usually under the control of the company or entity that requires its use Wide Area Network (WAN) A WAN is a network that is used to connect LANs... network HUB Figure 2-2 Hub connecting multiple hosts to a network When designing Ethernet networks, repeaters and hubs get treated the same way The 5-4-3 rule of Ethernet design states that between any two nodes on an Ethernet network, there can be only five segments, connected via four repeaters, and only three of the segments can be populated This rule, which seems odd in the context of today’s networks,... 2-4 illustrates how hubs operate As you might imagine, this model can become problematic in larger networks The traffic can become so intensive that the network becomes saturated—if someone prints a large file, everyone on the network will suffer while the file is transferred to the printer over the network Port 4 Port 5 Port 6 Port 7 Port 0 Port 1 Port 2 Port 3 Figure 2-4 Hubs repeat inbound signals... Antonio Campus Area Network (CAN) A CAN is a network that connects LANs and/or buildings in a discrete area owned or controlled by a single entity Because that single entity controls the environment, there may be underground conduits between the buildings that allow them to be connected by fiber Examples include college campuses and industrial parks Metropolitan Area Network (MAN) A MAN is a network that... collision domains A collision domain is an area of an Ethernet network where collisions can occur If one station can prevent another from sending because it has the network in use, these stations are in the same collision domain A broadcast domain is the area of an Ethernet network where a broadcast will be propagated Broadcasts stay within a layer-3 network (unless forwarded), which is usually bordered by . page you need.
