<human>:  What features distinguish a laptop from a desktop computer?
<bot>: A laptop is typically smaller and more portable than a desktop computer. It usually runs on a battery rather than a wall socket, and typically weighs less than a desktop as well. A laptop may also have fewer internal components than a desktop, such as a smaller processor and fewer RAM slots. Laptops also typically have a newer version of the operating system than a desktop. Additionally, a laptop may have a touchpad rather than a traditional mouse.
