| What are the intermediate devices? |
|
Definition
Intermediary devices connect the individual end devices to the network and can connect multiple individual networks to form an internetwork. These intermediary devices provide connectivity and ensure that data flows across the network
such as Routers, Wirless Router, Lan swtich, |

| What are the 4 basic characteristics of Networks? |
|
Definition
- Foul Tolerance
- Scalability
- Quality of Service (QoS)
- Security
|
|
|
Term
|
Definition
| A fault tolerant network is one that limits the impact of a failure, so that the fewest number of devices are affected. It is also built in a way that allows quick recovery when such a failure occurs. These networks depend on multiple paths between the source and destination of a message. If one path fails, the messages can be instantly sent over a different link. Having multiple paths to a destination is known as redundancy. |
|
|
Term
|
Definition
| A scalable network can expand quickly to support new users and applications without impacting the performance of the service being delivered to existing users. |
|
|
Term
| What does Quality of Service Stands for? |
|
Definition
ew applications available to users over internetworks, such as voice and live video transmissions, create higher expectations for the quality of the delivered services.
When the volume of traffic is greater than what can be transported across the network, devices queue, or hold, the packets in memory until resources become available to transmit them |
|
|
Term
| What does security stands for? |
|
Definition
| Information security refers to protecting the information contained within the packets being transmitted over the network and the information stored on network attached devices. |
