A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which usually weighs 2-18 pounds (1-6 kilograms), depending on size, materials, and other factors.
A laptop computer is much smaller than a desktop. Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.
As personal computers, laptops are capable of the same tasks as a desktop computer, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually 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, though an external keyboard or mouse can usually be attached.
A desktop computer is a computer made for use on a desk in an office or home and is distinguished from portable computers such as laptops or PDAs. Desktop computers are also known as microcomputers. There are four types of desktop computers: home computers, or personal computers; workstations, Internet servers, and special communications computers.
Desktops are currently the most affordable computers and ubiquitous in businesses, schools, and households; they are used for performing office tasks, organizing digital photos, video editing, and Internet access. Nearly all desktop computers are modular, with components that can easily be replaced or upgraded.
Desktop computers come in a variety of case styles ranging from large vertical towers to small form factor models that can be tucked behind an LCD monitor.
Desktop computers are commonly connected to a power strip.

Compaq Computer Corporation was an American personal computer company founded in 1982, and is now a brand name of Hewlett-Packard.
The company was formed by Rod Canion, Jim Harris and Bill Murto — former Texas Instruments senior managers. The name "COMPAQ" was derived from "Compatibility and Quality", as at its formation Compaq produced some of the first IBM PC compatible computers.
Once the largest supplier of computing systems in the world and previously regarded as perhaps the most reputable manufacturer of mid-range hardware, Compaq existed as an independent corporation until 2002, when it merged with Hewlett-Packard.
