Definition
| The most common type of wireless network system, centralized deployments, are traditionally used in campuses where buildings and networks are in close proximity. |
|
|
Term
|
Definition
| For small campuses or branch offices, converged deployments offer consistency in wireless and wired connections. This deployment converges wired and wireless on one network device—an access switch—and performs the dual role of both switch and wireless controller. |
|

Term
|
Definition
| This system uses the cloud to manage network devices deployed on premises at different locations. The solution requires Cisco Meraki cloud-managed devices, which provide full visibility of the network through their dashboards. |

Definition
| Combination of private and public networks |
|
|
Term

Definition
| is a type of topology that works on the functionality of the sender and receiver. It is the simplest communication between two nodes, in which one is the sender and the other one is the receiver. |
|
|
Term
|
Definition
| every device is connected to another device via a particular channel. Every device is connected to another via dedicated channels. These channels are known as links |
|
|
Term
|
Definition
| all the devices are connected to a single hub through a cable. This hub is the central node and all other nodes are connected to the central node. |
|
|
Term
|
Definition
| is a network type in which every computer and network device is connected to a single cable. It is bi-directional. It is a multi-point connection and a non-robust topology because if the backbone fails the topology crashes. |
|
|
Term
|
Definition
| it forms a ring connecting devices with exactly two neighboring devices. A number of repeaters are used for ____ topology with a large number of nodes, because if someone wants to send some data to the last node in the ____ topology with 100 nodes, then the data will have to pass through 99 nodes to reach the 100th node. |
|
|
Term
|
Definition
| is the variation of the ____ topology. This topology has a hierarchical flow of data |
|
|
Term
|
Definition
| is the combination of all the various types of topologies we have studied above. Hybrid Topology is used when the nodes are free to take any form |
