Networks
A network is a group of at least two devices that exchange data. Networks can be wired (LAN) or wireless (Wi-Fi). They enable the sharing of resources such as files, printers, and internet access.
Wi-Fi (Wireless Local Area Network)
A Wi-Fi network is a wireless local area network that connects devices within a limited area (e.g., an apartment, office, or café). It enables communication and data exchange without cables. A Wi-Fi can exist with or without internet access.
Example of a Wi-Fi network
A computer and a printer are connected to the same Wi-Fi. This allows the computer to send print jobs without the need for a cable. The network enables data exchange between the devices. If the Wi-Fi is also connected to the internet, both devices can use online services. Without internet access, the connection is limited to the local network.
Hotspot
A hotspot is a device or a location that provides Wi-Fi so that other devices can connect.
With Internet access: Connected devices can access the internet.
Without Internet access: Devices can only communicate locally (e.g., exchange files or use printers), but cannot go online.
Example of a Hotspot
A smartphone acts as a hotspot, providing Wi-Fi that other devices can use. A tablet connects to it and uses the smartphone’s cellular network to access the internet. This keeps the tablet online even when no other Wi-Fi network is available. If the smartphone itself does not have internet access, the connection works only locally, e.g., for file sharing between devices.
Distinctions
Network is the umbrella term for connected devices.
Wi-Fi is a wireless form of a local network.
Hotspot is a device or location that provides a Wi-Fi network, usually with a focus on internet access.
