Which topology uses a central device for point-to-point connections to other devices?
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.
How star topology works?
In a star topology, all devices are connected directly to a central hub or switch. This central device manages the flow of data between all connected devices, minimizing network collisions and enabling easy addition or removal of devices without affecting the network as a whole. However, if the central hub fails, the whole network can be affected.
Which topology are all devices connected to one another in a closed loop?
An old topology called Token Ring
What topology can only have a maximum of 20 devices connected to it?
it is the bus
A blank consists of a number of connectivity devices connected to a series of central connectivity devices such as hubs switches or routers in a hierarchy?
distributed backbone
In which topology are all devices connected in a closed loop?
It's called Ring.
What is the difference between network and topology?
Group of devices connected together forms a Network & structure (design) in which they interconnect is called Topology.
What is computer network topologies?
Here are some common types of network topologies: Bus Topology: In a bus topology, all devices are connected to a single central cable (the bus). Data travels along the bus and is received by all devices on the network. Each device has a unique address, and devices communicate directly with the bus. Star Topology: In a star topology, each device is connected directly to a central hub or switch. All data passes through the central hub, which manages and controls the flow of information between devices. If one device fails, it does not affect the rest of the network. Ring Topology: In a ring topology, each device is connected to two other devices, forming a closed loop or ring. Data travels in one direction around the ring. Devices act as repeaters to strengthen the signal as it passes through each device. Mesh Topology: In a mesh topology, every device is connected to every other device in the network. This creates multiple paths for data to travel, enhancing reliability and fault tolerance. Mesh networks can be full mesh (every device connected to every other device) or partial mesh (only some devices are interconnected). Tree Topology: Tree topology combines characteristics of star and bus topologies. Devices are arranged in a hierarchical structure, with multiple star networks connected to a central bus backbone. This allows for scalability and efficient data flow. Hybrid Topology: Hybrid topology combines two or more different types of topologies to form a larger network. For example, a network might combine elements of star and mesh topologies to create a more flexible and scalable network infrastructure. Each type of network topology has its advantages and disadvantages in terms of cost, scalability, reliability, and ease of management. The choice of topology depends on factors such as the size of the network, the type of applications used, and the level of redundancy and fault tolerance required.
What is the differences between star topology and bus topology?
A star topology has a central hub with other devices each connected to the hub but not to each other - for one device to communicate to another, they have to use the hub. With a bus topology all the devices are connected to the same bus - there is no hub. Each topology has advantages and disadvantages; the speed of a star network is limited by the hub; a telephone exchange is an example of a star network and there is a built-in limit to the number of devices that can be connected and there's no way to increase it other than to replace the hub with a bigger one. However, the devices (telephones in our example) can be dumb - all the intelligence is in the hub; it manages the calls and importantly, for commercial exchanges, calculates the bills. For bus networks, devices have to be smarter but can do much more as they can grab the whole bus.
What is the most commonly used physical topology?
The most commonly used physical network topology is the star topology. This design features a central device, such as a switch or hub, to which all other devices are connected. It is widely used in modern Ethernet networks due to its simplicity and ease of troubleshooting.
What is the arrangement of computer on the network?
The arrangement of computers on a network is called topology. It describes how the individual computers are connected to each other and to the network.examples of topology are Star topology, ring topology, mesh topology, bus topology.
What are 4 different network topologies?
The four different network topologies are: Star Topology: In this configuration, all devices are connected to a central hub or switch, allowing easy management and isolation of devices but creating a single point of failure. Bus Topology: All devices are connected to a single communication line or cable, which can be cost-effective but may lead to performance issues as more devices are added. Ring Topology: Each device is connected in a circular fashion, where data travels in one direction, providing consistent performance but making it vulnerable to failure if one device goes down. Mesh Topology: Devices are interconnected, allowing for multiple pathways for data to travel, enhancing reliability and redundancy but requiring more cabling and complexity in setup.
