The trackpad (or touchpad) is the smooth rectangle that you slide your finger around - instead of moving a mouse - to make the pointer / cursor move.
I think all laptops have them now, usually located centrally in front of the keyboard, with a couple of buttons above or below for left / right clicking.
Many laptops also have a small "nipple" pointing device located in the centre of the keyboard, again as a mouse substitute.
One or other or both of these can be disabled in the BIOS if you don't want them to work. The BIOS is the built-in hardware configuration utility that can be accessed at power-on before Windows loads - RTFM for your particular laptop.
