Network, WLAN, and Hotspot
Network
Section titled “Network”A network is a group of at least two devices that can exchange data. Networks can be wired (LAN) or wireless (WLAN). They are used to share resources such as files, printers, or Internet access.
WLAN (Wireless Local Area Network)
Section titled “WLAN (Wireless Local Area Network)”A WLAN is a wireless network that connects devices within a limited area (e.g., home, office, café). It enables communication and data transfer between devices without cables. WLAN can be operated with or without Internet access.
Example of a WLAN network:
Section titled “Example of a WLAN network:”A computer and a printer are connected via the same WLAN. The computer can send commands to the printer to print documents without the need for a cable. The resulting network enables communication between the devices and ensures that they can exchange data. If the WLAN is connected to the internet, both devices can also use online services; without the internet, the connection only works locally.
Hotspot
Section titled “Hotspot”A hotspot is a device or location that provides Wi-Fi so that other devices can connect to it.
With internet access: Connected devices can access the internet.
Without internet access: The devices can only communicate with each other locally (e.g., exchange files, use printers), but cannot go online.
Hotspot example:
Section titled “Hotspot example:”A smartphone provides a hotspot, i.e., a Wi-Fi network that other devices can use. A tablet connects to this hotspot to gain internet access via the cell phone’s mobile network. This allows the tablet to go online even when no regular Wi-Fi is available. Without internet access on the cell phone, the connection only works locally, e.g., for exchanging files between devices.
Distinction:
Section titled “Distinction:”Network is the general term for connected devices.
Wi-Fi is a wireless type of network.
Hotspot is a device or location that provides Wi-Fi, often with a focus on internet access.
