| NIC | network interface Card-controls media access |
| Ring | connects one host to the next and the last host to the first. This creates a physical ring of cable. |
| Extend star | topology uses the star topology to be created. It links individual stars together by linking the hubs/switches. This, as you will learn later in the chapter, will extend the length and size of the network. |
| Logical-token | controls network access by passing an electronic token sequentially to each host. |
| Hubs | extended star but instead of linking the |
| Switch | system is linked to a computer that controls the traffic on the topology. |
| Cloud | internet |
| Mesh | topology is used when there can be absolutely no break in communications, for example the control systems of a nuclear power plant. So as you can see in the graphic, each host has its own connections to all other hosts. |
| Bus | A bus topology uses a single backbone segment (length of cable) that all the hosts connect to directly. |
| Log-broadcast | The logical topology of a network is how the hosts communicate across the medium. |
| Media | two parts to the topology definition, the physical topology, which is the actual layout of the wire |
| Router | around the computers and around and around |
| Star | A star topology connects all cables to a central point of concentration. This point is usually a hub or switch, which will be described later in the chapter |
| Hierarchical | A hierarchical topology is created similar to an extended star but instead of linking the hubs/switches together, the system is linked to a computer that controls the traffic on the topology. |
| Repeater | reapeat over and over agian |
| Bridge | helps connects computers |
| RAM | random access memory, also known as Read-Write memory |
| ROM | read-only memory, computer memory on which data has been prerecorded |
| Backplane | the large circuit board that contains sockets for expansion cards |
| Video card | a board that plugs into a PC to give it display capabilities |
| Sound card | an expansion board that enables a computer to manipulate and output sounds |
| Mouse port | a port designed for connecting a mouse to a PC |
| Power cord | cord used to connect an electrical device to an electrical outlet in order to provide power to the device |
| Network card | an expansion board inserted into a computer so that the computer can be connected to a network |
