    • What is a network defined as?
      Computers connected by channels
    • Networks enable the sharing of resources and data between connected devices.
    • Networks can range from small home setups to large organizational networks and the global internet
    • What do network topologies describe?
      Device arrangement in a network
    • In a star topology, each device is connected to a central hub
    • A star topology is fault tolerant because the failure of one device does not affect the entire network.
    • What is the main cable in a bus topology called?
      Bus
    • A bus topology is easy to set up but has a single point of failure
    • How are devices connected in a ring topology?
      Circular fashion
    • A ring topology provides efficient data flow but is difficult to scale.
    • In a mesh topology, every device is connected to every other device
    • What is a key advantage of a mesh topology?
      High redundancy
    • Match the network type with its geographical scope:
      Personal Area Network (PAN) ↔️ Small area around an individual
      Local Area Network (LAN) ↔️ Limited area such as a home
      Metropolitan Area Network (MAN) ↔️ Spans a city
      Wide Area Network (WAN) ↔️ Covers countries or continents
    • What type of connection is commonly used in a PAN?
      Wireless
    • A LAN typically uses Ethernet or Wi-Fi
    • A MAN provides internet services to a city or metropolitan area.
    • What is the geographical scope of a WAN?
      Countries or continents
    • What is the purpose of network topologies?
      Describe device arrangement
    • In a star topology, devices are connected to a central hub
    • A bus topology is easy to troubleshoot.
      False
    • Arrange the following network topologies from least to most redundant:
      1️⃣ Bus Topology
      2️⃣ Ring Topology
      3️⃣ Star Topology
      4️⃣ Mesh Topology
    • The main cable in a bus topology is called the bus
    • What is a key advantage of a ring topology?
      Efficient data flow
    • Match the network type with its geographical scope:
      PAN ↔️ Small area around an individual
      LAN ↔️ Limited area such as a home
      MAN ↔️ City or metropolitan area
      WAN ↔️ Large geographical areas
    • A LAN connects devices within a limited area such as a school or office.
    • What type of network is commonly used for city-wide Wi-Fi?
      MAN
    • Malicious software that disrupts network operations is called malware
    • Phishing involves deceiving users to reveal sensitive information.
    • Arrange the following authentication methods from least to most secure:
      1️⃣ Passwords
      2️⃣ Biometric Authentication
      3️⃣ Multi-Factor Authentication
    • Match the access control model with its description:
      MAC ↔️ Centralized control, highly secure
      DAC ↔️ User-based control, flexible
      RBAC ↔️ Role-based control, efficient
    • A router forwards data packets between networks
    • What device directs data packets within a network?
      Switch
    • Network operating systems manage network operations and resources
    • A network enables the sharing of resources and data between devices.
    • What is a key advantage of a star topology in terms of fault tolerance?
      Central fault isolation
    • In a bus topology, all devices are connected to a single main cable
    • Which topology has devices connected in a circular fashion?
      Ring
    • A mesh topology offers high redundancy at the cost of complex setup and high costs.
    • Network topologies describe the arrangement of devices in a network.
    • What is the central device in a star topology?
      Hub or switch
