What is the characteristic of the bandwidth of a bus topology?
In a bus topology, the bandwidth is shared among all devices connected to the bus, leading to a limitation in data transmission rates as multiple devices communicate simultaneously. This can result in network congestion, particularly as the number of connected devices increases. Additionally, the overall bandwidth is determined by the capacity of the bus itself, which can be a bottleneck if not appropriately managed. Consequently, performance can degrade with heavy network traffic.
What is the physical topology?
Physical topology refers to the physical layout of devices and cables in a network. It defines how devices are connected to each other and how data flows between them. Common physical topologies include bus, star, ring, mesh, and hybrid.
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.
Which networking topology is difficult to reconfigure and a break in it disables the entire network?
The networking topology that is difficult to reconfigure and where a break can disable the entire network is the bus topology. In this configuration, all devices are connected to a single central cable, or "bus," which carries data signals. If there is a break or failure in the bus, it can disrupt communication for all devices connected to it, making troubleshooting and reconfiguration more challenging compared to other topologies.
What network uses a central cable to which all network devices connect?
bus network
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 are the types of bus topology?
There are two basic categories of network topologies Physical topologies Logical topologies The shape of the cabling layout used to link devices is called the physical topology of the network. Logical topology is the way the signals act in the network In BUS topology you have "THE LINEAR BUS" and "THE DISTRIBUTED BUS" IN the LINEAR bus all the nodes of the network are connected to a common transmission medium which has 2 end points where as in the DISTRIBUTED, all the nodes are connected to a common transmission medium which has more than 2 end points.
What's the definition of concept network topologies?
See related link for Network TopologiesTopology refers to the shape of a network , or the network's layout. How different nodes in a network are connected to each other and how they communicate are determined by the network's topology. Topologies are either physical or logical. Below are diagrams of the five most common network topologies.Mesh TopologyDevices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network.Star TopologyAll devices are connected to a central hub. Nodes communicate across the network by passing data through the hub.Bus TopologyAll devices are connected to a central cable, called the bus or backbone.Ring TopologyAll devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it.Tree TopologyA hybrid topology. Groups of star-configured networks are connected to a linear bus backbone.AlternativeDEF: A network (configuration) depiction made as an example by a techie.Omit the word concept together with the word techie for better understanding.
What topology can only have a maximum of 20 devices connected to it?

Which bus type is preferred for NIC that will be connected to a fast Ethernet network?
USB bus
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.
The concept of a network topology and the different types of topology?
A network topology refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network. Network Topologies: Bus All devices connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Star All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. Ring All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and span large distance. Hybrid Group of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. Wireless Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range.
