|
|
Term
|
Definition
| any device connected to a network such as a printer, a notebook computer, or a network switch |
|
|
Term
|
Definition
| a computer with hardware, software, and/or data resources to share on the network |
|
|
Term
|
Definition
| a computer that shares the resources provided by another node |
|
|
Term
|
Definition
| a network node that has the ability to act as a host for some resources and a client for others |
|
|
Term
|
Definition
| a type of node with its own processor and operating system, giving it the ability to support both local applications and run network applications |
|
|
Term
|
Definition
| a powerful computer that can support access to a shared resource by many simultaneous users |
|
|
Term
| NIC (network interface card); also network adapter |
|
Definition
| a hardware device through which a node is connected to the communications media of the network |
|
|
Term
|
Definition
| a common language used by a variety of dissimilar network devices to communicate with each other |
|
|
Term
|
Definition
| the ability of a network to continue to operate at an acceptable level in the event of a hardware, software, or media failure |
|
|
Term
|
Definition
| refers to both the physical arrangement of cabled and wireless network devices and the logical path data follows as it travels from device to device |
|
|
Term
|
Definition
| the pattern in which network cabling is laid in an office, a building, or a campus |
|
|
Term
|
Definition
| network layout in which cable runs between each node on a network |
|
|
Term
|
Definition
| network layout in which each node is connected to a common device |
|
|
Term
| demand for network services - number and kinds of applications used - network traffic - connections to other networks - security - growth potential |
|
Definition
| six considerations when selecting a network topology |
|
|
Term
|
Definition
| network topology in which nodes are connected together on a single cable like links in a chain |
|
|
Term
|
Definition
| device connected to the end of a bus cable segment to absorb leftover signals before they can be reflected back |
|
|
Term
| relatively inexpensive - requires less cable than other topologies - easy to extend bus with a workstation |
|
Definition
| advantages of the bus topology |
|
|
Term
| low fault tolerance - can become quickly congested with network traffic |
|
Definition
| disadvantages of the bus topology |
|
|
Term
|
Definition
| network topology in which nodes are connected on a continuous data path with no beginning or ending point |
|
|
Term
|
Definition
| type of ring topology implementation in which nodes are connected to two, independent data paths passing data in opposite directions |
|
|
Term
| easier to manage than bus - high fault tolerance in a redundant ring - suited to transmitting signals over long distances |
|
Definition
| advantages of the ring topology |
|
|
Term
| more expensive to implement than bus - has become outdated so there are fewer equipment options |
|
Definition
| disadvantages of the ring topology |
|
|
Term
|
Definition
| network topology in which nodes are connected to a central device |
|
|
Term
| hubs - switches - routers |
|
Definition
| three examples of network devices that may serve as the central device in a star topology |
|
|
Term
| start-up costs are much lower than other topologies - easier to manage - defective nodes can be quickly isolated - high fault tolerance - eEasier to expand by connecting nodes or networks |
|
Definition
| advantages of the star topology |
|
|
Term
| requires more cable than bus - failure of central device may cause network failure |
|
Definition
| disadvantages of the star topology |
|
|
Term
|
Definition
| network topology in which every node is connected to at least two other nodes in the network |
|
|
Term
|
Definition
| network topology in which every node is connected to every other node in the network |
|
|
Term
|
Definition
| network implementation most likely to use a mesh topology |
|
|
Term
|
Definition
| network topology in which a high-speed bus is used to connect multiple star-based LANs |
|
|
Term
|
Definition
| a high-speed (usually fiber-optic) cable used to connect the main hubs in a WAN |
|
|
Term
| easy to segregate network traffic so that communications in one limb of the tree can be isolated from other limbs |
|
Definition
| advantage of the tree topology |
|
|
Term
| may require more cable - if main trunk is down, connected limbs can not communicate with one another |
|
