Network Topologies Quiz Questions

Explanation
A hybrid network is a combination of two or more different network topologies. It allows for flexibility and scalability by utilizing the strengths of each topology. By combining multiple topologies, a hybrid network can provide redundancy, improved performance, and better fault tolerance. Therefore, the correct answer is "Two."

Explanation
A ring topology is the most basic topology because it connects all devices in a circular loop, where each device is connected to exactly two other devices. This creates a simple and straightforward network structure without any complex connections or central points of failure. In contrast, a square topology, hub topology, and mesh topology all involve more intricate connections and may have additional features or redundancies that make them more advanced than a basic ring topology.

Explanation
A hub-based network is a type of network where all devices are connected to a central hub. This hub is responsible for transmitting data between devices. The term "star" is used to describe this type of network because the devices are connected to the hub in a star-like pattern, with each device having its own separate connection to the hub. The term "star" is not related to any fish, so the answer "Star" is the correct one.

Explanation
In a local area network with a bus topology, all machines are connected to a single cable called the bus. This means that all data transmissions from one machine to another are sent through this single cable. Each machine on the network can receive the transmitted data, but only the intended recipient will process and respond to it. This type of network setup is commonly used in small-scale networks where simplicity and cost-effectiveness are prioritized over scalability and high bandwidth.

Explanation
A hybrid topology is not always produced when four different basic network topologies are connected. A hybrid topology is formed when two or more different network topologies are combined, not necessarily four. Therefore, the statement is false.

Explanation
The diagram shows a central node connected to multiple peripheral nodes in a pattern that resembles a star. This type of topology is known as a star topology. In a star topology, all nodes are connected directly to the central node, which allows for easy management and troubleshooting. Additionally, if one peripheral node fails, it does not affect the other nodes in the network.

Explanation
The statement is true because in a star topology, all devices are connected to a central hub or switch, making it easy to install and wire. Each device has its own dedicated connection to the central hub, which simplifies the installation process. Additionally, if one device fails or needs to be removed, it does not affect the connectivity of the other devices in the network. This ease of installation and wiring is a significant advantage of the star topology.

Explanation
A bus topology does not require more cable length than a star topology. In a bus topology, all devices are connected to a single cable, which reduces the amount of cable required compared to a star topology where each device is connected to a central hub with separate cables. Therefore, the statement is false.

Explanation
In a star network, data passes through a central hub, switch, or concentrator before reaching its intended destination. This central device acts as a central point of connection for all the devices in the network. Each device in the network is connected directly to the central hub, and when data is transmitted, it is first sent to the hub and then forwarded to the appropriate destination. Therefore, the statement that data on a star network passes through the hub, switch, or concentrator before continuing to its destination is true.

Explanation
The topology that uses token passing is the Ring topology. In this topology, the network nodes are connected in a circular manner, forming a ring. The token, which is a special control packet, circulates around the ring in a specific order. When a node wants to transmit data, it waits for the token to arrive, seizes it, attaches the data to it, and then releases it to continue circulating. This ensures that only one node can transmit at a time, preventing collisions and ensuring orderly communication.
