Wireless modem router: A wireless modem router allows communication between computers and the internet without cables.
A CD / DVD reader / writer: A reader / writer lets you both see what is on a disc, and convert your data into a digital format – either CD (Compact Disk) or DVD (Digital Versatile Disk).
Joysticks (or control stick): A joystick is a lever used to control the cursor for computer games or graphics.
Tablet: A tablet is an input device like an electronic pen and paper. Often used by artists, this allows you to use the stylus (pen) to write or draw on the tablet (flat surface) more naturally than a mouse.
USB stick / flash drive: A USB stick/ flash drive is a lightweight, removable, rewritable, data storage device with a USB connector.
