Laptops
A laptop computer or simply laptop (also notebook computer, notebook and notepad) is a little mobile computer, classically weighing 3-12 pounds (around 1.3 to 5.4 kilograms), though older laptops may weigh more.
Laptops generally run on a single main battery or from an external AC/DC adapter that charges the battery while also supplying power to the computer itself even in the event of a power failure. This very powerful main battery should not be puzzled with smaller 3 volt cell battery that is built in nearly every computer. This small battery is intended to run the real-time clock and backup BIOS configuration into the CMOS memory during the time the computer is not powered on and/or is not connected to the external power.
Laptops contain components that are similar to their desktop counterparts and perform the same functions, although are miniaturized and optimized for mobile use and efficient power consumption, although typically less powerful for the same price. Laptops generally have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, while an external keyboard or mouse can usually be attached.
