What are the advantages anddisadvantages of token ring topology?
Advantage: No packet collisions Disadvantage: Single point of failure
What physical network topology has the inherent weakness of a single point of failure?
The physical network topology that has the inherent weakness of a single point of failure is the star topology. In a star topology, all devices are connected to a central hub or switch. If this central device fails, the entire network becomes inoperable, as all communication relies on it. This makes the network vulnerable to disruptions if the hub experiences any issues.
Which physical network topologies has the inherent weakness of a single point of failure?
The bus topology has the inherent weakness of a single point of failure, as all devices are connected to a single central cable. If this main cable fails, the entire network becomes inoperable. Similarly, a star topology can also experience a single point of failure if the central hub or switch fails, disrupting communication for all connected devices. In both cases, the failure of one component can lead to a complete network outage.
What are the disadvantages for mesh star ring hybrid and bus topology?
Mesh star ring hybrid topology can be complex and costly to implement due to the need for extensive cabling and networking equipment, which increases maintenance efforts. Additionally, while it offers redundancy, the increased number of connections can lead to potential points of failure and network bottlenecks. In contrast, bus topology suffers from scalability issues, as the performance degrades with more devices, and a single point of failure can bring down the entire network. This makes troubleshooting more challenging and can lead to significant downtime.
What topology has a centralized location in which all the cables come together to a central point such that a failure at this point brings down the entire network?
The topology you're describing is known as a star topology. In a star topology, all network devices are connected to a central hub or switch, which acts as the main point of communication. If this central point fails, the entire network becomes inoperable, as no devices can communicate with each other. This design is often used for its simplicity and ease of troubleshooting, but it does create a single point of failure.
What topology allows for a single point of failure?
A star topology allows for a single point of failure, as all devices are connected to a central hub or switch. If this central device fails, communication across the entire network is disrupted, while individual devices can still function normally if they are not dependent on the hub. This design simplifies troubleshooting but also creates a vulnerability, as the failure of the hub affects the entire network.
which logical topology is best for a classroom environment?
A star topology is best for a classroom environment. This topology is easy to set up and manage, and it allows for easy expansion of the network. Additionally, it is less susceptible to network outages due to a single point of failure.
What physical network topologies has the inherent weakness of a single point of failure?
The star topology has the inherent weakness of a single point of failure, as all devices connect to a central hub or switch. If the central device fails, communication between all connected devices is disrupted. Similarly, the bus topology also exhibits this vulnerability; if the main cable (bus) fails at any point, it can halt the entire network's functionality. In both cases, the network's reliability is compromised by dependency on a single component.
What physical network topology is described as a single link between two nodes?

Why might a wireless mesh topology be superior to a base station topology for communications in a natural disaster?
-Failure during a single device won’t break the network. -There is no traffic problem as there is a dedicated point to point links for every computer. -Fault identification is straightforward. -This topology provides multiple paths to succeed in the destination and tons of redundancy. -It provides high privacy and security. -Data transmission is more consistent because failure doesn’t disrupt its processes. -Adding new devices won’t disrupt data transmissions. -This topology has robust features to beat any situation. -A mesh doesn’t have a centralized authority.
Why would you use a hybrid topology?
Reliable because a hybrid topology can diagnose and isolate faults efficiently. A network fault (such as a faulty node or a break in a network cable) will not affect the performance of the rest of the network. A hybrid network quickly scans all nodes and hardware points to detect where a fault lies, isolates it, and carries out further diagnostic tests. The rest of the network remains fully functional while this fault isolation and diagnosis is carried out. Flexible because I combine various configurations to bring about most optimal conditions to suit network traffic, processing loads and data latency. Hybrid networks can be expanded easily to add new systems and nodes. Each concentration point (or the point which a network connection is made) is designed to hold extra lobes. Additional network hardware peripherals can be attached to these lobes in order to increase capacity.A hybrid topology is able to tap into the strengths of other topologies and ignore their weaknesses. This results in a complex network that is more efficient and effective than individual topologies. It combines the optimal features of its combined topologies. For instance, a star-wired ring topology combines the features of a star topology with those of a ring topology. This hybrid topology combines the fault tolerance capability of the star topology with the data reliability of the ring topology. A star-wired bus topology combines the features of a star topology with a linear bus topology. It combines the network extension features of the bus topology with the simplicity and fault tolerance of the star topology.
