The most basic network is a Personal Area Network or PAN.
A PAN is a network that connects devices located within a relatively small area, typically within a person's personal space. This can include devices like smartphones, tablets, laptops, and other wearable devices.
A PAN can be created using different types of technologies like Bluetooth or Wi-Fi, which allow devices to communicate with each other and share resources such as files, internet connection, and printers, among others.
For example, if you have a smartphone and a wireless headset, you can create a PAN by connecting your phone to the headset via Bluetooth. This allows you to make and receive phone calls hands-free.
In summary, a PAN is the most basic network as it connects devices within a small personal area and is easy to set up and use. It is the foundation upon which larger and more complex networks like LAN, WAN, and MAN are built.
