In this article, we will delve into the world of Wi-Fi security and explore the possibilities of someone monitoring your online activities.
How Wi-Fi Works
To understand how someone might see what sites you visited on Wi-Fi, it’s essential to know how Wi-Fi works. Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. When you connect to a Wi-Fi network, your device sends a request to the router, which then grants you access to the network. Once you’re connected, you can browse the internet, send emails, or perform any other online activity.
Wi-Fi Network Types
There are several types of Wi-Fi networks, including public, private, and guest networks. Public Wi-Fi networks are those that are open to the general public, such as those found in coffee shops, airports, or hotels. Private Wi-Fi networks, on the other hand, are those that are restricted to specific individuals or groups, such as home networks or company networks. Guest networks are a type of private network that allows visitors to access the internet without giving them full access to the private network.
Public Wi-Fi Risks
Public Wi-Fi networks are particularly vulnerable to security risks. Since these networks are open to anyone, it’s easy for hackers to intercept your data or monitor your online activities. When you connect to a public Wi-Fi network, you’re essentially sharing the network with dozens of other people, which makes it difficult to ensure the security of your data. Using public Wi-Fi networks to access sensitive information, such as online banking or email, is not recommended, as it can put your personal data at risk.

What is a VPN and how does it work?
A VPN, or virtual private network, is a service that encrypts your internet traffic and protects your online activity from being intercepted and read by unauthorized parties. When you connect to a VPN, your internet traffic is routed through a secure server, which encrypts your data and hides your IP address. This makes it difficult for hackers, ISPs, and other third parties to see what sites you are visiting and what you are doing online.
VPNs work by establishing a secure connection between your device and the VPN server. This connection is encrypted using a protocol such as OpenVPN or L2TP/IPSec, which scrambles your internet traffic and makes it unreadable to anyone who intercepts it. The VPN server then forwards your internet traffic to its final destination, making it appear as though the traffic is coming from the VPN server’s IP address rather than your own. This provides an additional layer of anonymity and protection for your online activity, and can help protect you from hackers, trackers, and other online threats. By using a VPN, you can significantly reduce the risk of your online activity being intercepted and read by unauthorized parties.
