The Atom N270 laptop has three USB 2.0 ports.
There is no minimum or required number for USB ports on a laptop. Depending on the age and design of the laptop, it could be anywhere from zero to ten. I have seen only 2 USB ports on older laptops, most of the new ones atleast have 4 USB ports. Netbooks(10" & 11") have not more than 2 USB ports. If in anycase you need more USB ports, you could buy an USB hub for as less as 10$, which will add 4 more ports to your laptop.
Well depending on what usb ports it has usb 3 ports are the best to use.
This laptop features three Hi-Speed USB and four pin USB Type A ports.
All national ports have been closed.I need more USB ports on my laptop.
