Wi-Fi refers to a wireless technology that allows devices like smartphones, laptops, and tablets to connect to a local area network (LAN) wirelessly, typically within a limited range of a few hundred feet. It enables these devices to communicate with each other and access resources on the network without the need for physical wired connections.
The Internet, on the other hand, is a global network of interconnected computers and networks that spans the entire world. It allows devices connected to it to access a vast array of resources, such as websites, email services, online streaming platforms, and more, through various protocols and services like HTTP, FTP, and DNS.
Wi-Fi and the Internet are not the same thing. Wi-Fi provides local network connectivity within a specific area, whereas the Internet provides global connectivity to access resources and services beyond the local network.
You do not necessarily need both internet and Wi-Fi, depending on your requirements. If you only need to communicate or share data between devices within a local area, Wi-Fi alone may suffice. However, to access online services, websites, and resources beyond your local network, you would need an internet connection, which could be wired (e.g., Ethernet) or wireless (e.g., through a Wi-Fi router connected to an ISP).
Yes, you can have Wi-Fi without internet. Wi-Fi technology enables devices to connect to a local network for communication and resource sharing purposes, even if that network is not connected to the broader internet. This scenario is common in environments like home networks where devices can interact with each other locally through Wi-Fi without needing internet access.
