What is commonly referred to as a hotspot?

A hotspot is typically defined as a location where wireless networks, particularly Wi-Fi networks, are made available for public use. This can often be found in places like cafes, libraries, airports, and parks, allowing users to connect their devices to the internet without needing a personal data plan.

This concept emerges from the need for convenient access to the internet while on the go, providing both residents and travelers with the flexibility to connect their devices in various environments. The infrastructure of a hotspot usually involves a wireless router that enables devices within a certain range to access the network.

In contrast, the other options represent different concepts that do not align with the general understanding of a hotspot. Limited access networks might provide constraints on who can connect, which is not the essence of what a hotspot signifies. Ethernet connections, while related to networking, focus on wired connections rather than the wireless aspect that defines a hotspot. Lastly, a secure location for storing confidential data pertains to data security rather than providing internet access, which is the primary function of a hotspot.
