The update can be done in two ways, depending on the brand of your equipment and even the model of the terminal:
a) Via FOTA (Firmware Over The Air) or Through the Air: You will not need to connect the device with any cable to the computer. The update will be done, plain and simple, over the air. Remember, yes, to connect to a WiFi network.
b) Via USB: In this case, you will need to connect the phone with a USB cable to your computer. You will most likely also have to download a specific program for your brand of smartphone. In the case of Samsung, for example, you will need Kies.
