Client/Server Networking Model |
|
Definition
networking model is, without question, the most widely implemented model and the one you are most likely to encounter when working in real-world environments. |
|
|
Term
|
Definition
In a centralized computing model, one system provides both the data storage and processing power for client systems. This networking model is most often associated with computer mainframes and dumb terminals, where no processing or storage capability exists at the workstation. |
|
|
Term
|
Definition
A distributed network model has the processing power distributed between the client systems and the server. Most modern networks use the distributed network model, where client workstations share in the processing responsibilities. |

Definition
Wireless mesh networks are known as self-healing, which refers to the network’s capability to adapt to network failure and even function should a node be moved from one location to another. Selfhealing in a wireless mesh environment is possible because of the interconnected connections and because of the wireless media |
|
|
Term
You have been asked to install a network to give the network users the greatest amount of fault tolerance. Which of the following network topologies would you choose? |
|
Definition
A mesh network uses a point-to-point connection to every device on the network. This creates multiple points for the data to transmit around the network and therefore creates a high degree of redundancy. The star, ring, and bus topologies do not offer fault tolerance. |
|
|
Term
Which of the following topologies enables network expansion with the least amount of disruption for the current network users? |
|
Definition
On a star network, each network device uses a separate cable to make a point-to-point connection to a centralized device such as a hub or switch. With such a configuration, you can add a new device to the network by attaching the new device to the hub or switch with its own cable. |
