What has been a major driver for the development of the modern Internet?

• Increasing demand for faster file downloads

• The rise of new applications like telemedicine and smart grids

• The need for more secure email communication

• A reduction in the cost of data storage

Answer explanation

The rise of new applications like telemedicine and smart grids has significantly driven the development of the modern Internet, as they require advanced connectivity and infrastructure to function effectively.

What is the primary advantage of a fully connected mesh topology?

• It is the cheapest topology to implement

• It allows for more efficient use of bandwidth

• It provides high fault tolerance with multiple paths

• It reduces the number of network nodes needed

Answer explanation

The primary advantage of a fully connected mesh topology is its high fault tolerance. With multiple paths between nodes, if one connection fails, data can still be routed through alternative paths, ensuring network reliability.

Which topology is most vulnerable to a single point of failure?

• Ring

• Star

• Mesh

• Hybrid

Answer explanation

The star topology is most vulnerable to a single point of failure because if the central hub or switch fails, all connected devices lose communication. In contrast, ring, mesh, and hybrid topologies have more redundancy.

What is a key feature of a distributed (decentralized) network?

• It reduces the number of network devices

• It eliminates the risk of hotspots in the network

• It centralizes traffic control for higher efficiency

• It is only used in wireless networks

Answer explanation

A key feature of a distributed network is that it eliminates the risk of hotspots by distributing data and traffic across multiple nodes, preventing any single point from becoming overwhelmed.

In modern data networks, which topology is often combined with others to ensure both performance and fault tolerance?

• Fully connected mesh

• Tree topology

• Hybrid topology

• Bus topology

Answer explanation

Hybrid topology combines multiple topologies to enhance performance and ensure fault tolerance, making it a versatile choice for modern data networks.
