What Is WiFi, And How Does It Work?

WiFi is a technology that facilitates wireless communication over short distances using radio waves. There are two types of WiFi, the newer and faster 802.11ac WiFi which has the most bandwidth, and the older 802.11g WiFi which has about 20% less bandwidth but has been around for years. In this article, you will learn what WiFi is, how it works, and some important terms to know!

What Is WiFi?

WiFi is a wireless technology that allows devices to connect to the internet. It is also used to connect devices in a home or office. WiFi uses radio waves and works even with walls between rooms.

How Does WiFi Work?

WiFi is a type of wireless technology that uses radio waves to connect between devices in close proximity. WiFi is most commonly used in homes and businesses, but it can also be used in public places like airports, malls, and restaurants. WiFi signals travel through the air easily, allowing them to reach more devices than traditional wireless technologies.

WiFi Terms and Phrases you need to know

WiFi is a term used to describe the wireless networking technology used in homes and businesses. WiFi networks use radio waves to connect devices within range.

WiFi is different from mobile phone networks because WiFi networks are designed for short-range connections, like connecting a laptop to an ethernet port in a room. Mobile phone networks use long-range radio waves to connect phones to each other and to the towers that provide coverage.

WiFi signals travel through the air just like radio or TV signals, but they’re weaker because they have to travel over longer distances. WiFi networks can be found in more places than mobile phone networks. WiFi also works inside buildings, which means you can connect your laptop to the network in your office and access the internet even if you’re not near an open window.

Different Kinds of Wireless Networks

WiFi is a wireless networking technology that uses radio frequencies to connect devices within a limited range. WiFi networks are typically found in homes and offices and can be used to connect devices such as laptops, smartphones, and tablets. WiFi networks can also be used to share files, download content, and access the internet.

WiFi Security

WiFi is short for wireless fidelity and it’s a wireless networking technology that allows devices to connect to the internet. WiFi uses radio waves to send and receive data. WiFi networks are typically found in homes and businesses but can also be found in public places like airports, libraries, and parks.

There are two types of WiFi networks: open and secured. An open WiFi network is not protected by a security protocol and anyone can access it without authentication or password. A secured WiFi network uses a security protocol like WEP or WPA to protect the network from unauthorized access.

To connect to a secured WiFi network, your device must have a security certificate that is issued by a trusted Certificate Authority (CA). Your device will display a security prompt when it attempts to connect to a secure network. If you don’t have a security certificate, your device will not be able to connect to the network.

Many people use their smartphones as hotspots to connect their laptops to the internet. When you use your smartphone as a hotspot, all the data that flows through the phone’s connection is unprotected. Anyone who has access to your smartphone can view your browsing history, passwords, and other sensitive information.
