<P> A subtype of desktops, called nettops, was introduced by Intel in February 2008, characterized by low cost and lean functionality . A similar subtype of laptops (or notebooks) is the netbook, described below . The product line features the new Intel Atom processor, which specifically enables nettops to consume less power and fit into small enclosures . </P> <P> A home theater PC (HTPC) is a convergence device that combines the functions of a personal computer and a digital video recorder . It is connected to a TV set or an appropriately sized computer display, and is often used as a digital photo viewer, music and video player, TV receiver, and digital video recorder . HTPCs are also referred to as media center systems or media servers . The general goal in a HTPC is usually to combine many or all components of a home theater setup into one box . More recently, HTPCs gained the ability to connect to services providing on - demand movies and TV shows . HTPCs can be purchased pre-configured with the required hardware and software needed to add television programming to the PC, or can be cobbled together out of discrete components, what is commonly done with software support from MythTV, Windows Media Center, GB - PVR, SageTV, Famulent or LinuxMCE . </P> <P> A laptop computer (also called a notebook) is similar to a desktop, but is designed for portability . Usually, all of the hardware and interfaces needed to operate a laptop, such as the graphics card, audio devices or USB ports (previously parallel and serial ports), are built into a single unit . Laptops usually have "clamshell" design, in which the keyboard and computer components are on one panel and a flat display screen on a second panel, which is hinged to the first panel . The laptop is opened for use and closed for transport . Closing the laptop also protects the screen and keyboard during transportation . Laptops have both a power cable that can be plugged in and high - capacity batteries that can power the device, enhancing its portability . Once the battery charge is depleted, it will have to be recharged through a power outlet . In the interests of saving power, weight and space, laptop graphics cards are in many cases integrated into the CPU or chipset and use system RAM, resulting in reduced graphics performance when compared to an equivalent desktop machine . For this reason, desktop computers are usually preferred over laptops for gaming purposes . </P> <P> One of the drawbacks of laptops is that, due to the size and configuration of components, usually relatively little can be done to upgrade the overall computer from its original design or add components . Internal upgrades are either not manufacturer - recommended, can damage the laptop if done with poor care or knowledge, or in some cases impossible, making the desktop PC more modular and upgradable . Desktop PCs typically have a case that has extra empty space inside, where users can install new components . Some internal upgrades to laptops, such as memory and hard disk drive upgrades are often easily performed, while a display or keyboard upgrade is usually difficult or impossible . Just like desktops, laptops also have the same input and output ports for connecting to a wide variety of devices, including external displays, mice, cameras, storage devices and keyboards, which may be attached externally through USB ports and other less common ports such as external video . Laptops are also a little more expensive compared to desktops, as the miniaturized components for laptops themselves are expensive . </P>
