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.
What network has a single communication channel that is shared by all the users on the?
That is called a bus topology.
Which LAN topology involves the network cable forming a single bus to which every workstation is attached?
The LAN topology that involves the network cable forming a single bus to which every workstation is attached is called the bus topology. In this setup, all devices share a single communication line, and data travels in both directions along the bus. The main advantage of bus topology is its simplicity and ease of installation, but it can be prone to collisions and performance issues as more devices are added. Additionally, if the main cable fails, the entire network goes down.
Deine the topology and explain the advantage and disadantage of bus star and ring topology?
Topology is the structure that describes how devices in a Network are connected.Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.Advantage of Bus Topology is that less connecting cable is used.Advantage of Star Topology is that Network can function in case one or more devices fail.Disadvantage of Bus Topology is that whole Network goes down if one device fails.Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.
What physical topology consists of a single cable that connects all nodes on a network without intervening connectivity devices?
it is a ring network
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 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.
Is mesh topology multipoint topology?
Mesh topology is not typically classified as a multipoint topology. In mesh topology, each device is connected to multiple other devices, creating a network where data can be routed through multiple paths, enhancing redundancy and reliability. In contrast, multipoint topology often refers to a single communication channel shared among multiple devices, where only one device can transmit at a time. Therefore, while both topologies involve multiple devices, their structures and functionalities differ significantly.
Does a bus topology connect all devices to a common backbone?
Yes, a bus topology connects all devices in a network to a single communication line, known as the backbone. Each device taps into this backbone to send and receive data, which allows for a straightforward and cost-effective network setup. However, if the backbone fails, the entire network goes down, making it less reliable than other topologies.
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 happens when a bus topology wire fails?
In a bus topology, all devices are connected to a single central cable, or bus. If this wire fails, all devices downstream of the break lose their connection to the network, resulting in a communication failure for those devices. However, devices upstream of the failure can still communicate with each other. This vulnerability makes bus topologies less reliable compared to other network topologies like star or ring.
