- Je suis un triangle. J'ai un angle droit et deux côtés de même longueur. Qui suis-je ?
- The logical topology is determined by the intermediary devices and the protocols chosen to implement the network.
- Interactivity, real-time responsiveness, amount of data generated, burstiness, drop sensitivity, criticality to business
- Availability indicates how much time a network is accessible and operational
- every workstation is connected to a common transmission medium, a single cable, which is called a backbone or bus
- In a full mesh topology, every node is connected to every other node
- there is a central device to which all other network devices connect via point-to-point links
- Network virtualization creates a software solution that emulates network services and functions.
- Media are the physical elements that connect network devices
- In a ring topology, computers and other network devices are cabled in succession, and the last device is connected to the first one to form a circle or ring
- sp^3 (2 doublets d'électrons et deux atomes autour l'atome centrale)
- The physical topology of a network refers to the physical layout of the devices and cabling
- In a mesh topology, a device can be connected to more than one other device. For one node to reach others, there are multiple paths available. Redundant links increase reliability and self-healing.
- it helps organizations centrally automate and provision the network from a central management point.
- In partial mesh, certain nodes do not have connections to all other nodes.
- QoS is essential for prioritizing traffic when the network is congested.
- Bitrate measures the data rate in bits per second (bps) of a given link in the network
- it is an end-user devices (PCs, laptops, tablets, mobile phones, game consoles, and television sets)
- networks should be designed to limit the impact of failures and to allow quick recovery when a failure does occur
- The logical topology is the path which data travels from one point in the network to another.
