Study Notes
Chapter 7: Networking: Connecting Computing Devices
- This chapter covers networking concepts, including the pros and cons of computer networks, different network types, transmission media, necessary hardware and software, and broadband internet access options.
- Learning objectives include describing computer networks and their pros and cons, explaining different network definitions, describing transmission media types, hardware for networks, network software types, and summarizing broadband internet access options. -Additional objectives involve wireless internet access, home network setup considerations, problems with wireless networks and solutions, and securing wireless home networks.
Networking Fundamentals
- A computer network connects two or more computers for communication using software and hardware.
- Each device on a network is a node, including computers, peripherals (printers, game consoles), and network devices (routers).
- Benefits of networks include sharing a high-speed internet connection, printers and other devices, files, and communication.
- The main disadvantage of networks is setup time.
Network Architectures
- Networks are classified by distance:
- Personal Area Network (PAN): Communication among devices close to one person.
- Local Area Network (LAN): Devices located in a small geographical area.
- Home Area Network (HAN): LAN within a home.
- Metropolitan Area Network (MAN): Large network serving a city.
- Wide Area Network (WAN): Spans a large physical distance.
- Networks can also be classified by administration level:
- Client/Server Network: Clients request information from a central server.
- Peer-to-Peer (P2P) Network: Each node can communicate directly with others.
- Networks are also classified by protocol:
- Ethernet: A network protocol developed by the Institute of Electrical and Electronics Engineers (IEEE).
- Wireless networks (Wi-Fi)
- Wired networks (Gigabit Ethernet [GbE])
- Backward compatibility: the ability of current devices to use earlier standards
Network Components
- Network components include:
- Means of connection (cables or wireless technology).
- Hardware devices for communication and data transfer.
- Software to run the network.
- Network adapter/ NIC (provides network connectivity)
- Modems (for broadband connections)
- Routers (for transferring data between networks)
- Switches ( for managing data flow on a network).
Transmission Media
- Transmission media establishes a communication channel between network nodes, either wireless or wired.
- Wired media includes UTP cable (twisted copper wires), coaxial cable (single copper wire), and fiber-optic cable (plastic or glass fibers).
Network Software
- Operating systems support peer-to-peer (P2P) networks.
- Client/server networks use specialized network operating systems (NOS) for centralized servers.
Connecting to the Internet
- Broadband is the preferred internet access method.
- Broadband types include cable, DSL, and fiber-optic service.
- Wireless internet access methods include mobile broadband, wireless internet at home, mobile hotspots, wireless ISPs, and data plans.
Installing and Configuring Home Networks
- Planning considerations include listing connected devices and using the latest networking standards and equipment.
- Specialized home networking devices include network-attached storage (NAS) devices, home network servers, and network-ready devices.
- Routers and switches are used to manage data flow and connectivity.
Troubleshooting Wireless Networks
- Maximum Wi-Fi range is limited, and walls/metal objects can create interference.
- Placing access points where the signal is weak can help.
- Wireless extenders repeat/amplify router signals.
Managing Wireless Networks
- Use encryption and security protocols.
- Change the network name (SSID)
- Disable SSID broadcast.
- Change the default password
- Creating a passphrase
- Limit signal ranges
- Implementing media access control
- Keeping router firmware updated
- Disabling remote access
