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.
In information technology, a server is an application or device that performs services for connected clients as part of a client-server architecture. A server application, is "an application program that accepts connections in order to service requests by sending back responses." Server computers are devices designed to run such an application or applications, often for extended periods of time with minimal human direction. Examples of servers include web servers, e-mail servers, and file servers.

Apple Inc. (NASDAQ: AAPL, LSE: ACP, FWB: APC) is an American consumer electronics multinational corporation with worldwide annual sales in its fiscal year 2006 (ending September 30, 2006) of US$19.3 billion. Headquartered in Cupertino, California, Apple develops, sells, and supports a series of personal computers, portable media players, computer software, and computer hardware accessories. The company's best-known products include the Mac line of personal computers, its Mac OS X operating system, and the iPod line of portable media players. For the iPod and its related iTunes software, Apple sells audio books, games, music, music videos, TV shows, and movies in its online iTunes Store.
The company was known as Apple Computer, Inc. for its first 30 years of existence, but dropped "Computer" from its corporate name on January 9, 2007. The name change, which followed Apple's announcement of its new iPhone smart phone and Apple TV digital video system, is representative of the company's ongoing expansion into the consumer electronics market in addition to its traditional focus on personal computers.
Apple also operates 180 (as of April 2007) retail stores in the United States, Japan, the United Kingdom, Canada, and Italy. The stores carry most of Apple's products as well as many third-party products and offer on-site support and repair for Apple hardware and software. Apple employs over 20,000 permanent and temporary workers worldwide.
For a variety of reasons, ranging from its philosophy of comprehensive aesthetic design to its countercultural, even indie roots, as well as their advertising campaigns, Apple has engendered a distinct reputation in the consumer electronics industry and has cultivated a customer base that is unusually devoted to the company and its brand.

Apple and the enviroment
Environmental protection is a priority for the conservation of precious natural resources and the continued health of our planet. Apple recognizes its responsibility as a global citizen and is continually striving to reduce the environmental impact of the work we do and the products we create.
Apple and the Global Environment
Apple takes pride in its history of innovation and thoughtful design. But technological leadership goes beyond what’s in the box. How we impact the environment is also important to us, and environmental considerations are an integral part of Apple’s business practices. From the earliest stages of product design through manufacturing, use, and recycling, we take care to keep our activities and our products environmentally sound.
Four areas of particular attention are product and packaging design, responsible manufacturing, energy efficiency, and recycling. Each aspect of the design cycle provides significant challenges, yet our efforts in these areas have resulted in some impressive results.
It all begins here. Reducing the environmental impact of our products starts with the product design phase. Design dictates the quantity of raw materials, type and recylability of materials, energy consumption required for manufacturing and use, and the ease of recycling. For example, our decision to eliminate Cathode Ray Tube (CRT) displays makes our product line much more environmentally friendly. Our flat-panel displays eliminate more than two pounds of lead, consume up to 80% less energy in sleep mode, and weigh half as much as their CRT counterparts.
Apple continually refines its product design to maximize efficiency while minimizing waste, following the requirements of programs such as ENERGY STAR® as well as our own high standards.
Apple helps to safeguard the environment — as well as consumers’ safety — by restricting the use of environmentally harmful compounds in our materials and manufacturing processes. For example, our restricted substances program limits the use of heavy metals and ozone depleting substances in our products and manufacturing processes.
A device’s greatest environmental impact is often its energy consumption over time. Apple has made great strides in recent years to optimize the energy efficiency of our hardware and created tools, such as the Energy Saver feature in Mac OS X, that allow consumers to manage the power consumption of their computers. Since 2001, all Apple computers and displays have earned the ENERGY STAR® rating.
Apple’s holistic approach to recycling — encompassing a product’s entire lifecycle — includes extensive take-back programs that enable consumers and businesses to dispose of used Apple equipment in an environmentally sound manner. Since our first take-back initiative began in Germany in 1994, we have launched programs in the United States, Canada, Japan, and throughout Europe, diverting over 34 million pounds of electronic equipment from landfills worldwide.
A history of sound practice
Year after year, Apple has set and met important goals to phase out environmentally relevant substances, create recycling programs worldwide and improve energy efficiency. Here are some of the most important milestones in our quest for environmental responsibility:
1990 Apple’s environmental policy released and implemented.
1991 Phase-out of lead in batteries in advance of the 1996 European battery directive.
1992 Phase-out of chlorofluorocarbons (CFCs) in Apple manufacturing, as stipulated in the Montreal Protocol on Substances That Deplete the Ozone Layer.
