Network Topologies Quiz Questions

Explanation
A star topology is a network configuration where all devices are connected to a central connection point, such as a hub, switch, or router. In this configuration, each device has a direct connection to the central point, allowing for easy management and troubleshooting. The central point acts as a central hub for data transmission, facilitating efficient communication between devices. This topology is commonly used in small to medium-sized networks as it provides a high level of reliability and scalability.

Explanation
In a ring topology, hosts are connected in a physical ring or circle. This means that each host is connected to two other hosts, creating a continuous loop. Because the ring has no beginning or end, the cable does not need to be terminated. This allows for easy expansion of the network by simply connecting additional hosts to the ring.

Explanation
In a mesh topology, all devices are connected to each other in a point-to-point manner. This means that each device has a direct connection to every other device in the network. This type of topology provides high redundancy and fault tolerance, as there are multiple paths for data to travel. However, it also requires a large number of physical connections and can be costly to implement.

Explanation
In a bus topology, each computer connects to a common cable. This means that all computers on the network share the same communication medium, which is the bus or the main cable. Each computer can send and receive data on the bus, and the data is broadcasted to all computers connected to the network. This type of topology is relatively simple and inexpensive to implement, but it can be prone to congestion and network failures if the main cable is damaged.

Explanation
A hierarchical or extended star topology is a star network with an additional networking device connected to the main networking device. This topology is characterized by a central networking device (usually a switch or hub) that connects to multiple secondary networking devices, forming a hierarchical structure. Each secondary device can also have additional devices connected to it, creating multiple levels of connectivity. This topology allows for better scalability and flexibility in network design.

Explanation
Ethernet LAN networks can utilize the star, bus, and hierarchical or extended star physical topologies. In a star topology, all devices are connected to a central hub or switch. In a bus topology, all devices are connected to a single cable. In a hierarchical or extended star topology, multiple star topologies are connected together in a hierarchical manner. These physical topologies allow for efficient communication and connectivity between devices in an Ethernet LAN network.

Explanation
In a token ring type LAN network architecture, a star topology is used. This means that all devices in the network are connected to a central hub or switch, forming a star-like structure. In a token ring network, devices take turns sending data using a token, which circulates around the network. The star topology allows for easy management and troubleshooting, as each device is connected directly to the central hub. Additionally, it provides better scalability and flexibility, as new devices can be easily added to the network without disrupting the existing connections.
