What Do You Know About Ring Networks?

Explanation
The term "network topology" refers to the arrangement or layout of the elements in a communication network. It describes how the devices (such as computers, routers, switches) are connected and how the data flows between them. Different types of network topologies include star, bus, ring, mesh, etc. "Network topology" is the correct answer as it directly addresses the arrangement of elements in a communication network.

Explanation
Physical topology refers to the arrangement of the physical components of a network, such as computers, servers, switches, and cables. It determines how these components are physically connected and laid out within the network. This includes the placement of devices, the type of cables used, and the overall structure of the network. Physical topology plays a crucial role in determining the network's performance, scalability, and fault tolerance. It can be represented in various forms such as a star, bus, ring, or mesh topology.

Explanation
Entrance facilities refer to the point where the telephone company network terminates and connects with the on-premises wiring at the customer premises. It is the physical location where the external network infrastructure meets the internal wiring of a building or property. This is where the telephone company's lines enter the customer's premises and are connected to the internal telephone system. It is an essential component in establishing communication between the telephone company's network and the customer's telecommunication equipment.

Explanation
A riser cable is a cable that is run between floors in non-plenum areas. Plenum cable is used in plenum areas, which are spaces used for air circulation in buildings. Star cable and ring cable are not specific types of cables used for running between floors in non-plenum areas.

Explanation
A Media Access Unit is a device used to attach multiple network stations in a star topology as a token ring network. It is responsible for controlling the access to the network and passing a token between stations to allow them to transmit data. This unit ensures that only one station can transmit at a time, preventing data collisions and ensuring efficient communication within the network.

Explanation
Logical topology refers to the way in which data flows within a network. It defines the path that data takes from one device to another and how devices are interconnected. It helps to illustrate the arrangement of devices, connections, and communication paths in a network. The other options, such as ringing, nodes, and ranking, do not specifically relate to the flow of data within a network.

Explanation
A coaxial cable is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, which is then surrounded by a tubular conducting shield. This design helps to minimize signal loss and interference, making it ideal for transmitting high-frequency signals.

Explanation
Token ring is the correct answer because it is a networking protocol that uses a special three-byte frame called a token to control access to the network. In a token ring network, workstations are connected in a logical ring, and the token circulates around the ring, allowing each workstation to transmit data when it receives the token. This ensures fair access to the network and prevents collisions.

Explanation
In a star network, the centre hub acts as a conduit to transmit messages. The centre hub is the central point of connection for all the devices in the network. It receives messages from one device and transmits them to the intended recipient device. The centre hub ensures efficient communication by managing the flow of data and directing it to the appropriate destination.

Explanation
A computer or other device connected to a computer network is called a host. A host is a node on a network that can send, receive, or process data. It can be a computer, server, printer, or any other device that is connected to the network. The term "host" is commonly used in networking to refer to any device that participates in network communication.
