Computers are a wonderful invention that have changed over the years. At the beginning, computers were so large that they took up all of the space in an entire room. Today, computers are so small that they can fit into the palm of someone’s hand. Computers used to store information, but now they can analyze information and provide fast ways of communication. Today, a computer only includes one small machine that includes a screen. Before, a desktop computer included a monitor that would sit on the desk and a CPU box that would have to be placed near the computer. The keyboard and mouse would have to be hooked up to both the monitor and CPU box.
