Wi-Fi and internet are often used interchangeably, but they are not exactly the same thing. While Wi-Fi is a type of wireless networking technology, internet refers to the global network of interconnected computers and servers. So, do you need internet for Wi-Fi? The answer is a resounding “no,” but there’s more to it than that. In this article, we’ll explore the differences between Wi-Fi and internet, and examine the scenarios where you can have Wi-Fi without internet.
The Difference Between Wi-Fi and Internet
To understand whether you need internet for Wi-Fi, it’s essential to understand the difference between these two terms.
Wi-Fi is a type of wireless networking technology that allows devices to connect to each other without the use of cables or wires. It uses radio waves to transmit data between devices, and it’s commonly used in homes, offices, and public hotspots. Wi-Fi is a local area network (LAN) technology, which means it’s designed to connect devices within a limited geographical area.
Internet, on the other hand, is a global network of interconnected computers and servers that communicate with each other using standardized protocols. The internet is a wide area network (WAN) that spans the entire globe, connecting billions of devices and systems.
In other words, Wi-Fi is a way to connect devices to a network, while the internet is the network itself. You can have Wi-Fi without internet, but you can’t have internet without some form of connectivity, such as Wi-Fi, Ethernet, or cellular networks.
