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 detail the components and functionality of computer networks.
Learning Objectives
- 7.1: Describe computer networks and their advantages and disadvantages.
- 7.2: Explain different methods of classifying networks.
- 7.3: Describe wireless and wired transmission media used in networks.
- 7.4: Describe essential hardware components necessary for networks (ex. network adapters, modems, routers, switches).
- 7.5: Outline the types of software needed for computer networks.
- 7.6: Summarize broadband options available for accessing the internet.
- 7.7: Explain wireless Internet access methods.
- 7.8: Considerations for creating a home network (devices, standards, equipment).
- 7.9: Describe the setup of a home network, including routers and switches.
- 7.10: Troubleshoot wireless network problems (e.g., signal range, interference).
- 7.11: Methods for securing wireless home networks (encryption, passwords, etc.).
- 7.12: Configuring security settings on a router (SSID, security protocols).
Networking Fundamentals
- Computer network: A system of two or more computers connected to share information and resources.
- Node: Each device (computer, peripheral, or network device) connected to a network.
- Benefits: Sharing high-speed internet, printers, files, and facilitating communications.
- Disadvantages: Network setup and administration.
- Data transfer rate (bandwidth): Maximum data transmission speed.
- Throughput: Actual data transfer speed.
- Units: Measured in megabits per second (Mbps) and gigabits per second (Gbps).
Network Architectures
-
Networks can be categorized by distance (e.g., PAN, LAN, HAN, MAN, WAN).
-
Personal area network (PAN): Short-range connections for devices around one person.
-
Local area network (LAN): Network in a small geographical area (e.g., home, office).
-
Home area network (HAN): A specific type of LAN found within a home.
-
Metropolitan area network (MAN): Network connecting multiple devices within a city.
-
Wide area network (WAN): Networks covering large geographical areas (e.g., countries).
-
Client/server network: A network where a central server handles requests from client computers.
-
Peer-to-peer (P2P) network: Network where each device can communicate directly with any other device.
Network Components
-
Protocols (e.g., Ethernet, Wi-Fi): Standards that define how data travels through networks.
-
Ethernet: Common wired standard
-
Wi-Fi: Wireless standard for networks.
-
Transmission media: Method for connecting devices (wired/wireless). This includes UTP, coaxial and fiber optics cables.
-
Hardware: Network devices like network interface cards (NICs), modems, routers, switches.
- NIC: Network interface card; allows devices to communicate on a network.
- Modem: Converts digital signals to analog signals and back to allow communication over phone lines.
- Router: Transfers data packets between different networks.
- Switch: Acts like a traffic controller for data packets on a network.
-
Software: Network operating system (NOS) software manages network operations and resources. This is important for home networks(P2P) and client-server networks.
Connecting to the Internet
-
Broadband: High-speed internet access (e.g., cable, DSL, fiber optic).
- Cable Internet: Uses coaxial cables.
- DSL: Uses existing telephone lines.
- Fiber optic: Uses light pulses.
- Cellular/dial-up: Alternative internet options if broadband isn't available.
Installing and Configuring Home Networks
- Necessary stepsinclude devices, the latest standards and equipment.
- Types of devices for a home network include routers and switches.
- Specialized networking devices are network-attached storage (NAS) devices and home network servers.
Troubleshooting and Securing Wireless Networks
-
Troubleshooting: Identify common problems like weak signals, interference.
-
Troubleshooting strategies: Use a wireless range extender, and select an optimal access point.
-
Security: Methods for securing a wireless network (encryption through security protocol, changing network name; disabling SSID broadcast, changing default password and creating a passphrase ). Network security involves several factors like, limiting radio waves, employing media access control, and keeping router firmware up-to-date.
