    Study Notes

    Chapter 7: Networking: Connecting Computing Devices

    • This chapter covers networking concepts, focusing on connecting computing devices.
    • Learning objectives include describing computer networks, their pros/cons, and different network definitions.
    • Other objectives include describing transmission media, hardware, software, broadband internet options, wireless internet access, home network setup, potential problems with wireless networks, and securing wireless home networks.

    Networking Fundamentals

    • A computer network connects two or more computers.
    • Each device on the network is called a node.
    • Nodes can be computers, peripherals (like printers), or network devices (such as routers).
    • Networks allow data sharing, high-speed internet access, printer sharing, and common communications.
    • A major disadvantage of networks is setup time.

    Data Transfer Rates

    • Data transfer rate or bandwidth is the maximum speed at which data can be transmitted.
    • Throughput is the actual speed at which data is transferred.
    • These speeds are measured in megabits per second (Mbps) or gigabits per second (Gbps).

    Network Architectures

    • Networks can be categorized by distance.
      • Personal Area Network (PAN): Communication among devices close to a person.
      • Local Area Network (LAN): Network within a small geographical area.
      • Home Area Network (HAN): A specific LAN type in a home.
      • Metropolitan Area Network (MAN): A large network covering a city.
      • Wide Area Network (WAN): Spans a large physical distance.
    • Networks are also categorized by levels of administration.
      • Client/server network: Clients request information from a central server.
      • Peer-to-peer (P2P) network: Each node can communicate directly with every other node.
    • Networks are also classified via protocols used, such as Ethernet.

    Network Components

    • Network function requires:
      • A connection method (cables or wireless).
      • Special hardware to allow communication.
      • Software to run the network.
    • Transmission media establish communication channels between network nodes and can be wireless or wired.
      • Wired networks use UTP cable (twisted copper wires), coaxial cable (single copper wire), or fiber-optic cable (plastic or glass fibers).
    • Basic network hardware includes: network adapter (NIC) , modem to translate digital signals, router to send data between networks, and switch to direct data within a network.

    Network Software

    • Operating systems support P2P networking.
    • Client/server networks use a centralized server for communication.
    • Specialized network operating system (NOS) software is typical in client/server systems.

    Connecting to the Internet (Broadband)

    • Home networks usually share an internet connection purchased from an Internet Service Provider (ISP).
    • Broadband is the preferred type of internet access.
    • Common broadband types include cable internet, DSL, and fiber-optic service.

    Connecting to the Internet (Wireless)

    • Mobile broadband, wireless internet (at home), mobile hotspots, wireless ISPs, and data plans are used for wireless internet access.
    • WiFi is used through routers for home networks and mobile hotspots when away from home.

    Installing and Configuring Home Networks

    • Planning involves listing devices, using the latest standards, and utilizing the newest equipment.
    • Optimized routers are available for specific computer systems.
    • Specialized home networking devices like NAS (Network Attached Storage) and home networking servers are examples of network-ready devices.

    Troubleshooting Wireless Networks

    • Common issues include interference from walls, floors, metal objects, and reduced signal range from distance.
    • Wireless range extenders can be crucial in extending the signal.

    Managing and Securing Wireless Networks

    • Security measures include using encryption, changing the network name (SSID), disabling SSID broadcast, changing the default password, and creating a passphrase.
    • Implementing media access control, limiting signal range, and keeping router firmware up-to-date are additional security measures.
