What is the difference between the Internet and WiFi?
The Internet is a vast network that connects millions of private, public, academic, business, and government networks worldwide. It allows users to access information, communicate, and share resources across the globe. In contrast, WiFi (Wireless Fidelity) is a technology that enables devices to connect to a local network without the need for physical cables. Essentially, WiFi serves as a bridge between your devices and the Internet.
WiFi creates a local area network (LAN) that lets devices like laptops, smartphones, and tablets communicate with each other and share resources. However, to access the Internet through a WiFi network, you need a broadband connection, such as DSL, cable, or fiber. Without this broadband connection, WiFi can only facilitate local network activities, not access the broader Internet.
