Why do you need to connect your smartphone to the PC? Of course, it's not necessary, but it is easiest to pump the photos, books and other multimedia content from PC to smartphone and Vice versa.

How to connect your smartphone to PC or laptop via USB?

When you purchase most models of smartphones set gadget is attached to a special cable, one end of which connector is mini USB, another standard USB. Using such a cable is very easy to connect your smartphone to the computer.

Useful tip: if your smartphone didn't come with such a cable, purchase it separately, it is still useful.

The connection process

After connecting the cable to the computer and the smartphone, wait a moment to let the PC recognize the device connected to it.

The smartphone also detects that it is connected to PC. To verify this, lower the bar by moving up and down and you will see a notification that USB connected. The smartphone can switch to USB mass storage mode to transfer data to it and back.

I must say that to connect your smartphone to computer or laptop do not have to use the USB cable. It is possible to connect via Bluetoth or Wi-Fi, however, this requires, firstly, that both devices have the appropriate wireless adapters based on the smartphone they usually are built), and second, you must install specific software.

Selection and configuration of appropriate software, in this case, a process that requires objective assessment of the tasks that will be solved with the help of this connection and also some knowledge of system administration, so I don't recommend using this type of connection for the trivial file transfer a user between the above devices (unless included with your phone is not going ON that supports this data transfer method).
