4.1.2 Network topologies:

• What is a computer network?

  Interconnected devices sharing resources
• Match the network topology with its definition:

  Bus ↔️ Devices connected to a single cable

  Star ↔️ Devices connected to a central hub

  Ring ↔️ Devices connected in a circular fashion

  Mesh ↔️ Devices connected to multiple others
• The topology of a network refers to its physical and logical arrangement
• In a bus topology, all devices are connected to a single cable.


  True
• In a star topology, all devices are connected to a central hub
• Order the following network topologies from least to most reliable:

  1️⃣ Bus

  2️⃣ Star

  3️⃣ Ring

  4️⃣ Mesh
• In a ring topology, data travels in one direction
• Central device failure in a star topology can halt the entire network
• What are the main types of network topologies?

  Bus, Star, Ring, Mesh
• Which topology is more reliable than the bus topology?

  Star
• A mesh topology is highly reliable due to its redundant paths
• What factors influence the choice of network topology?

  Cost, reliability, scalability
• What does network topology refer to?

  Physical and logical arrangement
• What is a critical disadvantage of the star topology in a network?

  Central hub failure
• What is a key advantage of the bus topology?

  Simple setup
• What is required in a ring topology to avoid data collisions?

  Token passing
• Match the network topology with its characteristic:

  Bus ↔️ Single point of failure

  Star ↔️ Central hub failure

  Ring ↔️ Requires token passing

  Mesh ↔️ Highly reliable redundant paths
• The bus topology is easy to expand but has a single point of failure.

  True
• What happens to the network if a device is removed in a ring topology?

  It disrupts the network
• A star topology is commonly used in a home network or office LAN
• What type of network required token ring passing and is now rare?

  Ring topology
• What is network topology concerned with?

  Physical and logical arrangement
• The choice of network topology depends on cost, reliability, and scalability requirements.

  True
• What is a characteristic of a bus topology?

  Single point of failure
• Which topology requires token passing to avoid collisions?

  Ring
• A mesh topology is more expensive than a star topology due to redundant connections.


  True

• Data in a ring topology travels in one direction

  True
• Match the network topology with its characteristic:

  Mesh ↔️ Redundant paths
• A computer network is a collection of interconnected devices
• In a star topology, a central hub failure can halt the entire network
• All devices in a bus topology are connected to a single cable
• The star topology is more reliable than the bus topology.


  True
• The mesh topology is highly reliable due to its redundant connections
• What factors influence the choice of network topology?

  Cost, reliability, scalability
• In a star topology, all devices are connected to a central hub
• Match the network topology with its characteristic:

  Bus ↔️ All devices on a single cable

  Star ↔️ Central hub for connections

  Ring ↔️ Data travels in one direction

  Mesh ↔️ Redundant connections for reliability
• Where might a bus topology be used in the real world?

  Small office LAN
