What is a PC for?

Today, the PC has fallen into common use and is used for just about everything. He entered everyday life. The list of advantages of the personal computer is not exhaustive. A PC serves:

  • Store personal information and get rid of paperwork. Your PC allows you to save space in your home and to better organize your information. Administrations and companies have opted for personal spaces which keep documents formerly classified in boxes.

You can watch movies and series on thanks to companies like Netflix… which has rented more than five billion DVD since its creation. The DVD market is not dead.
