A light pen is a light-sensitive computer input pointing device shaped like a wand. It is connected to a visual display unit or CRT monitor and allows the user to modify data and text or make menu selections on the screen. Light pens became popular during the 1980s.
A ballpoint pen is a writing instrument that dispenses ink via a metallic sphere at the pen's tip. There are two main types of ballpoint pens: disposable and refillable. Disposable pens contain a fixed plastic ink cartridge and are discarded when the ink is used up. Refillable pens have a removable ink cartridge that can be replaced when empty. Disposable pens are made from plastic while refillable pens are made from either metal or plastic.
