Cable: Data is transmitted through coaxial cables. It is a high-speed internet connection but can be affected by network congestion and slow down during peak usage times.
DSL: Data is transmitted through traditional phone lines. It is widely available and can be less expensive than other high-speed internet connections but can be slower than other options.
Cellular: Data is transmitted through cellular towers. It is widely available and convenient for mobile users but can be expensive and may have limited data usage.
Wireless Internet service provider (WISP): Data is transmitted through wireless signals. It is available in remote areas and can be an affordable option but may have limited coverage and speeds.
Network types
Local area network (LAN): A network that connects devices in a small geographic area, such as a home or office. It typically uses wired or wireless connections and can be used for sharing resources such as printers or files.
Wide area network (WAN): A network that connects devices over a large geographic area, such as a city or country. It typically uses the internet or other networks to connect devices and can be used for remote access to resources.
Personal area network (PAN): A network that connects devices in a very small geographic area, such as a person's workspace. It typically uses wireless connections and can be used for devices such as wireless keyboards or headphones.
Metropolitan area network (MAN): A network that connects devices in a metropolitan area, such as a city. It typically uses fiber-optic cables and can be used for connecting organizations or government entities.
Storage area network (SAN): A network that connects storage devices to servers. It typically uses fiber-optic cables and can be used for high-speed data transfer.
Wireless local area network (WLAN): A network that uses wireless connections to connect devices in a small geographic area. It can be used for accessing the internet or sharing resources such as printers or files.
Each type of internet connection and network type has its own advantages and disadvantages. The choice of which to use depends on the specific needs of the user or organization.
2.7 Given a scenario, use networking tools with function
Crimper : You might use a crimper tool to terminate the ends of Ethernet cables with RJ45 connectors.
Cable stripper: You might use a cable stripper tool to remove the outer insulation from a piece of Ethernet cable in order to expose the individual wires inside.
WiFi analyzer: You might use a WiFi analyzer tool to troubleshoot wireless network issues by analyzing wireless signals and identifying sources of interference.
Toner probe: You might use a toner probe tool to trace the path of a particular cable or identify which cable corresponds to a specific port on a switch or patch panel.
Punchdown tool: You might use a punchdown tool to terminate Ethernet cables in a patch panel or keystone jack.
Cable tester: You might use a cable tester tool to check the continuity and integrity of Ethernet cables to ensure they are properly terminated and capable of transmitting data.
Loopback plug: You might use a loopback plug tool to test the functionality of network interfaces by connecting a device to itself.
Network tap: You might use a network tap tool to monitor network traffic by intercepting packets and forwarding them to a monitoring device for analysis.
