In bus topology if ends are not conected then what happens?
If the ends of a bus topology network are not terminated then you will get 'signal bounce'. This will cause all packets to collide with each other, and the net effect is that the network is unusable.
What network characteristic involves the arrangmnent of cable network device and end system as well as the paths data signal take thorugh the network?
Topology
Discuss the consequences if a connection fails in a bus topology?
Any connection failure in a bus topology will result in the network becoming unusable due to signal bounce in the affected cable.
What kind of topology is susceptible to signal bounce?
A BusSource: Page 195 Network+ Guide to Networks 5e
Is bus topology faster than star topology?
In terms of speed, bus topology and star topology are comparable since both can offer high data transmission rates. However, bus topology may experience more performance issues such as signal interference and collisions since all devices share the same communication line, potentially affecting overall network speed.
What is a logical network designtopology?
Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data -- the physical structure of the network -- is called the physical topology. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. Logical topologies are bound to the network protocols that direct how the data moves across a network. The Ethernet protocol is a common logical bus topology protocol. LocalTalk is a common logical bus or star topology protocol. IBM's Token Ring is a common logical ring topology protocol. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.

What is a network tropology?
The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.In communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.The physical topology of a network is the actual geometric layout of workstations.above tropologies are described belowBus - Both ends of the network must be terminated with a terminator. A barrel connector can be used to extend it.Star - All devices revolve around a central hub, which is what controls the network communications, and can communicate with other hubs. Range limits are about 100 meters from the hub.Ring - Devices are connected from one to another, as in a ring. A data token is used to grant permission for each computer to communicate.
How host on physical ring topology communicate?
A ring topology connects neighboring nodes until they form a ring. * signals than travels in one direction around the ring; each device on the network acts as a repeater to send the signal to the next device.
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.
How do you identify a particular feedback topology in a circuit?
For analyzing the feedback amplifier, it is necessary to go through the following steps. Step 1 : Identify topology ( Type of feedback) 1. To find the type of sampling network (i) By opening the output if feedback signal becomes zero, then it is called "voltages sampling" (ii) By shorting the output loop if feedback signal becomes zero, Then it is called "Current Sampling" 2. To find the type of mixing network (i) If the feedback signal is subtracted from the externally applied signal as a voltage in the input loop, it is called "Series Mixing" (ii) If the feedback signal is subtracted from the externally applied signal as a current in the input loop, it is called "Shunt Mixing" Thus by finding the type of sampling network and mixing network, type of feedback amplifier can be determined. for example, If amplifier users a voltages sampling and series mixing, then it is called a voltages series amplifier
Why terminators are used in a bus topology?
So that the Signal will not reflact back due to difference of permitivity of signals that causes destructive interfrance... They are used in End of Bus topology
