In the contemporary society, people need laptops and desktop computers to do a variety of activities, including long distance communication, playing music, creating databases, just to mention a few. Laptops and desktop computers have a number of typical components, which include a keyboard, display, speakers, hard disk, motherboard, RAM, and many other components. A person can use either a desktop computer or a laptop to execute the same program successfully. However, laptop computers are suitable for mobile use while desktop computers are suitable at single locations. This is because desktop computers are heavy and use only direct current, as opposed to laptops, which use direct current and alternate current as well as being light. Therefore, laptops differ from desktop computers in terms of design, but achieve the same purpose of program execution. This discussion will consider comparison and contrast between desktop and laptop computers. Laptop computers can use alternate current when the user is far from electricity because they have inbuilt batteries. This characteristic of laptops enables users to operate their computers even during the event of a power outage. On the other hand, desktop computers use direct current as the only source of power, which means that users cannot operate them in case of a power outage. Therefore, laptops should be portable to utilize the functionality of alternate current.
In addition to having inbuilt batteries, laptops weigh less and are small sized, which make them portable. Users can carry their laptops around while travelling, and they can work from any location. A laptop is a single unit with all components, such as keyboard, mouse, monitor, webcam and speakers built in it. Therefore, users do not need to connect and disconnect such components every time when there is a need to change locations. Unlike the portable laptop computers, most of the desktop computers are heavy, which makes them not portable. Many components, such as the monitor, keyboard, mouse, speakers, and webcam, which make up a desktop computer, are separate, and the user must connect all the components correctly for the computer to be functional. Users must also disconnect all the components and pack them well before moving from one place to another when changing locations. In case a user misplaces some components like the power cable, the computer cannot be functional until the user buys another power cable.

: : : Laptop computers are extremely expensive in today’s computer market and some components, such as the monitor, are delicate and require users to handle with care. Therefore, many people may not afford to purchase laptop computers because of the high cost. Many desktops are extremely cheap in today’s computer market, which makes them affordable to most people in the contemporary society. Desktop computers are more robust than is the case with laptop computers. For instance, the monitors consist of a hardened glass that cannot crack easily, which is contrary to the delicate screen of a laptop computer. In conclusion, it is apparent that both laptop and desktop computers can achieve the same goal of executing computer programs. Both laptop and desktop computers become functional when the essential components such as a keyboard, monitor, hard disk, motherboard, RAM, and others are in place. However, laptops differ significantly from desktop computers in terms of size, weight, and connection of components. Laptops are small sized and weigh less as compared to desktop computers, which are voluminous and heavy. Laptop computers have inbuilt components, while many components in desktop computers are separate and a user must connect them to the central processing unit for the computer to be complete and functional. Desktop computers are robust while laptops are delicate because the screen is extremely slim.

A desktop computer is a personal computer that is designed to fit conveniently on top of a typical office desk. A desktop computer typically comes in several units that are connected together during installation: (1) the processor, which can be in a microtower or minitower designed to fit under the desk or in a unit that goes on top of the desk, (2) the display monitor, (3) and input devices usually a keyboard and a mouse. Today, almost all desktop computers include a builtin modem, a CDROM drive, a multigigabyte magnetic storage drive, and A laptop computer, usually called a notebook computer by manufacturers, is a battery or ACpowered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings. A laptop typically weighs less than 5 pounds and is 3 inches or less in thickness. Among the bestknown makers of laptop computers are IBM, Apple, Compaq, Dell, and Toshiba. Laptop computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. Different between laptop and desktopFunction All types of computers perform similar functions, but the difference is generally that desktop computers have more robust specifications and more computing power for the dollar compared to their more portable laptop cousins. Comfort is another function that is traded away in favor of portability when it comes to laptop computers, which generally have a touchpad that is not as easy to use as the mouse that comes standard with a desktop computer Memory and Storage * Small Outline Dual Inline Memory Module (SODIMM)* Dual Data Rate Synchronous RAM (DDR SDRAM)* Single data rate Synchronous RAM (SDRAM) * Proprietary memory modules Some laptops have upgradeable memory and feature removable panels for easy access to the memory modules. Desktop computers have multiple bays for installing additional drives, such as CD and DVD ROM drives. However, space in a laptop is in much shorter supply. Many laptops use a modular design, allowing a variety of drives to fit in the same bay. Size Component Desktops have several standardized expansion slots, like Conventional PCI or PCI 6 express, while laptops only tend to have one mini PCI slot and one PC card slot (or ExpressCard slot). This means that a desktop can be customized and upgraded to a greater extent than laptops. Procedures for (dis)assembly of desktops tend to be simple and standardized to a great extent too. This tends not to be the case for laptops, though adding or replacing some parts, like the optical drive, hard disk, and adding an extra memory module is often quite simple. Performance Battery Upgradeability The reasons for limited upgradeability are both technical and economic. There is no industrywide standard form factor for laptops; each major laptop manufacturer pursues its own proprietary design and construction, with the result that laptops are difficult to upgrade and have high repair costs. With few exceptions, laptop components can rarely be swapped between laptops of competing manufacturers, or even between laptops from the different productlines of the same manufacturer. Some upgrades can be performed by adding external devices, either USB or in expansion card format such as PC Card. Devices such as sound cards, network adapters, hard and optical drives, and numerous other peripherals are available, but these upgrades usually impair the laptop’s portability, because they add cables and boxes to the setup and often have to be disconnected and reconnected when the laptop is on the move. Portability Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs.[38] Portability means that a laptop can be used in many places—not only at home and at the office, but also during commuting and flights, in coffee shops, in lecture halls and libraries, at clients’ location or at a meeting room, etc. The portability feature offers several distinct advantages: Productivity Immediacy : If a person has more than one desktop PC, a problem of synchronization arises: changes made on one computer are not automatically propagated to the others. There are ways to resolve this problem, including physical transfer of updated files (using a USB flash memory stick or CDRs) or using synchronization software over the Internet. However, using a single laptop at both locations avoids the problem entirely, as the files exist in a single location and are always uptodate. Connectivity : A proliferation of WiFi wireless networks and cellular broadband data services (HSDPA, EVDO and others) combined with a nearubiquitous support by laptops means that a laptop can have easy Internet and local network connectivity while remaining mobile. WiFi networks and laptop programs are especially widespread at university campuses. Motherboard
