4.1.1 Understanding types of networks:

• What is a computer network?

  Collection of nodes connected
• Protocols in a computer network govern data transmission and reception.


  True
• What type of connection is typically used in a LAN?

  Wired or short-range wireless
• A WAN is typically owned and managed by a single organization.

  False
• LANs generally have faster speeds compared to WANs
• A MAN's geographic area is larger than a LAN but smaller than a WAN.


  True
• MANs often have high speeds ranging from 100 Mbps to 1 Gbps
• Bluetooth is a common PAN technology.


  True
• What is the range of a Personal Area Network (PAN)?

  10 meters
• Match the geographic area with the network type:

  Personal ↔️ PAN

  Small (home, office) ↔️ LAN

  Large (across cities, countries) ↔️ WAN
• What type of connection is used in a WAN?

  Long-range wireless
• PANs are typically owned by a single organization.

  False
• Physical or wireless channels linking nodes are called connections
• LANs cover a small geographic area such as a home or office.

  True
• A Metropolitan Area Network (MAN) connects multiple LANs within a city
• What is an example of a Metropolitan Area Network (MAN)?

  City-wide network
• Bluetooth, ZigBee, and NFC are common PAN technologies.


  True
• What is the typical speed range of a PAN?

  1-24 Mbps
• A Wireless Personal Area Network (WPAN) uses wireless technologies within a 10-meter range.


  True
• Smartphones, smartwatches, and other wearables are often connected via Bluetooth.
• Match the network type with its characteristic:

  LAN ↔️ Small geographic area

  WAN ↔️ Multiple organizations

  MAN ↔️ City-wide region

  PAN ↔️ Personal use
• Order the network types by geographic area from smallest to largest:

  1️⃣ PAN

  2️⃣ LAN

  3️⃣ MAN

  4️⃣ WAN
• In a computer network, a node refers to an individual device like a computer, server, or peripheral
• Match the network type with its geographic area:

  LAN ↔️ Small area (e.g. home, office)

  WAN ↔️ Large area (e.g. cities, countries)
• The speed of a WAN is generally slower compared to a LAN
• Match the network component with its description:

  Nodes ↔️ Devices in the network

  Connections ↔️ Channels linking nodes

  Protocols ↔️ Rules for data transmission
• Which network type covers a larger geographic area, LAN or WAN?

  WAN
• What is a Metropolitan Area Network (MAN)?

  Connects LANs within a city
• What type of connection is commonly used in a MAN?

  Fiber optics
• What is a Personal Area Network (PAN)?

  Device network within 10 meters
• Common PAN technologies include Bluetooth, ZigBee, and NFC
• The speed of a PAN is moderate, ranging from 1 to 24 Mbps.


  True
• The speed of a LAN ranges from 100 Mbps to 10 Gbps
• What are the three key components of a computer network?

  Nodes, connections, protocols
• Match the protocol with its example:

  Data transmission ↔️ TCP/IP

  Web browsing ↔️ HTTP
• What type of connection is commonly used in LANs?

  Ethernet, WiFi
• Match the network type with its connection type:

  MAN ↔️ Fiber optics

  LAN ↔️ Ethernet

  WAN ↔️ Satellite
• A Personal Area Network (PAN) is used for communication within a range of about 10 meters.
• Match the network type with its geographic area:

  PAN ↔️ Personal

  LAN ↔️ Small

  WAN ↔️ Large
• A PAN is typically owned by a single person.
