Personal Area Network (PAN) is the most basic type of computer network. This network is restrained to a single person, that is, communication between the computer devices is centered only to an individual’s workspace. PAN offers a network range of 10 meters from a person to the device providing communication.
Examples of PAN are USB, computer, phone, tablet, printer, PDA, etc.
Wireless Local Area Network (WLAN) is a type of computer network that acts as a local area network but makes use of wireless network technology like Wi-Fi. This network doesn’t allow devices to communicate over physical cables like in LAN but allows devices to communicate wirelessly.
The most common example of WLAN is Wi-Fi.
Virtual Private Network (VPN) is a type of computer network that extends a private network across the internet and lets the user send and receive data as if they were connected to a private network even though they are not. Through a virtual point-to-point connection users can access a private network remotely. VPN protects you from malicious sources by operating as a medium that gives you a protected network connection.
