Study Notes

Chapter 7: Networking: Connecting Computing Devices

  • This chapter covers networking concepts, including types of networks, transmission media, hardware, software, and Internet access options.
  • Learning objectives outline key topics to be learned.

Learning Objectives (1 of 2)

  • Describe computer networks and their pros and cons.
  • Explain different ways networks are defined.
  • Describe types of transmission media used in networks.
  • Describe basic hardware devices necessary for networks.
  • Describe the type of software necessary for networks.
  • Summarize broadband options available to access the Internet.

Learning Objectives (2 of 2)

  • Summarize how to access the Internet wirelessly.
  • Explain things to consider before creating a home network.
  • Describe how to set up a home network.
  • Describe potential problems with wireless networks and how to avoid them.
  • Describe how to secure wireless home networks.

Networking Fundamentals

  • A computer network connects two or more computers to communicate.
  • Each device on a network is called a node.
  • Nodes can include computers, peripherals, and network devices like routers.

Benefits of Networks

  • Share high-speed Internet connection.
  • Share printers and peripheral devices.
  • Share files.
  • Facilitate common communications.

Disadvantages of Networks

  • Network setup and administration.

Data Transfer Through Networks

  • Data transfer rate (bandwidth) is the maximum data transmission speed.
  • Throughput is the actual data transfer speed.
  • Speed is measured in megabits per second (Mbps) and gigabits per second (Gbps).

Network Architectures

  • Networks are classified by distance:

    • Personal Area Network (PAN): Communication among devices close to a person.
    • Local Area Network (LAN): Nodes in a small geographical area.
    • Home Area Network (HAN): Specific type of LAN in a home.
    • Metropolitan Area Network (MAN): Large network covering a city.
    • Wide Area Network (WAN): Spans a large physical distance.

  • Networks are also classified by administration levels:

    • Client/server network: Clients request information from a central server.
    • Peer-to-peer (P2P) network: Nodes directly communicate with each other.

Classifying Networks by Protocols

  • Ethernet: Developed by the IEEE (Institute of Electrical and Electronics Engineers).
    • Supports both wired and wireless networks.
  • Backward compatibility: Ability of current devices to use older network standards.

Network Components

  • Connecting nodes (cables/wireless technology).
  • Hardware devices for communication (network adapters, NICs, modems, routers, switches).
  • Software to run the network.

Network Hardware

  • Network adapter: Integrated adapter (NIC), broadband connections use modems.
  • Network navigation devices: Facilitate and control data flow (routers, switches).

Network Software

  • Operating system for P2P networking
  • Client/server network communications through a central server; specialized network operating system (NOS) software.

Connecting to the Internet

  • Broadband Internet connections are preferred, but cellular or dial-up access may also be necessary.

  • Common broadband technologies include cable, DSL, and fiber-optic.

Connecting to the Internet: Wireless Access

  • Mobile broadband uses 4G or 5G wireless access.
  • Wireless internet at home uses WiFi through a router.
  • Mobile hotspot provides internet access away from home.

Installing and Configuring Home Networks

  • List all devices.
  • Use latest standards for equipment.
  • Routers are specific to devices (iPhones, Windows PCs). Switches facilitate traffic.

Specialized Home Networking Devices

  • Network-attached storage (NAS) devices for data storage and access.
  • Home network servers for file storage and sharing.
  • Network-ready devices connect to the network.

Troubleshooting Wireless Network Problems

  • Maximum range of about 350 feet.
  • Walls, floors, metal objects interfere with signals.
  • Place access point where signal is weak.
  • Wireless range extenders repeat or amplify signals.

Managing and Securing Wireless Networks

  • Use encryption and security protocols.
  • Change Network Name (SSID).
  • Disable SSID broadcast.
  • Change default password.
  • Create a passphrase.
  • Implement media access control (MAC).
  • Limit signal range.
  • Update router firmware.
  • Disable remote access.
