Network Topologies and Functions

The video tutorial explains the concept of network nodes and topologies, highlighting the difference between logical and physical arrangements. It provides examples of various network topologies such as ring, bus, star, and mesh, and discusses how real-life networks, like those in schools, often use hybrid topologies. The tutorial also touches on historical contexts, such as switchboards, and how automation has replaced manual operations with software solutions.

What is a node in the context of a network?

• A network protocol

• A software application

• A device that connects to a network

• A type of network cable

What does a logical topology describe?

• The physical arrangement of cables

• The type of network devices used

• How data flows within the network

• The color of network cables

Which topology involves a central medium that all nodes can access?

• Bus

• Mesh

• Ring

• Star

Which topology is characterized by having one node more important than others?

• Bus

• Mesh

• Tree

• Star

What is a hybrid network?

• A network using only one type of topology

• A network with no physical connections

• A network that only uses wireless connections

• A network that combines different topologies

In a hybrid network, what is the significance of logical arrangement?

• It determines the physical layout of cables

• It defines how different topologies are interconnected

• It limits the number of devices on the network

• It specifies the color coding of network cables

What was the role of an operator in old switchboard systems?

• To repair broken telephones

• To manufacture network cables

• To connect calls by arranging wires

• To design network topologies

How does a switchboard system function logically?

• As a tree topology

• As a mesh topology

• As a point-to-point topology

• As a bus topology

What is the physical topology of a switchboard system?

• Star

• Mesh

• Ring

• Bus

How have operators been replaced in modern telecommunication systems?

• By eliminating the need for connections

• By using automated software

• By using manual switchboards

• By hiring more human operators
