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.
