What is Wi-Fi? | Definition, Meaning & Drawbacks



Wi-Fi technology allows devices to connect to the internet wirelessly. It works by using radio waves to transmit data between a device and a router, which is a device that connects to the internet and enables the connection of multiple devices. The router broadcasts a wireless signal, which devices can then connect to and access the internet.


One of the main advantages of Wi-Fi is its convenience and flexibility. It allows devices to connect to the internet from anywhere within range of the wireless signal, as long as they have a Wi-Fi-enabled device and the necessary login credentials. This makes it easy to connect to the internet in a variety of settings, including public places like coffee shops, airports, and libraries, as well as in private homes and offices.

Wi-Fi is also a cost-effective solution for internet access, as it does not require physical cables to be installed. This makes it an appealing option for households and businesses, especially in cases where it is not practical to install cables.


There are some potential drawbacks to using Wi-Fi as well. The signal can be disrupted by physical obstacles such as walls or furniture, which can affect the strength and stability of the connection. Additionally, Wi-Fi can be vulnerable to security breaches, so it is important to use strong passwords and keep the router's firmware up to date to protect against unauthorized access.


In summary, Wi-Fi is a useful technology that allows for convenient and flexible internet access. It is widely used in a variety of settings and can be a cost-effective solution for households and businesses. However, it is important to be aware of potential issues such as signal disruptions and security risks.
