What is the difference between a Laptop and Desktop computer
A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A “complete” computer including the hardware, the operating system and peripheral equipment required and used for “full” operation can be referred to as a computer system.
THE DIFFERENCE BETWEEN A LAPTOP AND DESKTOP COMPUTER
Laptop computer, also known as notebooks, are portable computers that you can take with you and use in different environments. They include a screen, keyboard, and a trackpad or trackball, which serves as the mouse. Because laptops are meant to be used on the go, they have a battery which allows them to operate without being plugged into a power outlet. Laptops also include a power adapter that allows them to use power from an outlet and recharges the battery.
While portable computers used to be significantly slower and less capable than desktop computers, advances in manufacturing technology have enabled laptops to perform nearly as well as their desktop counterparts. In fact, high-end laptops often perform better than low or even mid-range desktop systems. Most laptops also include several I/O ports, such as USB ports, that allow standard keyboards and mice to be used with the laptop. Modern laptops often include a wireless networking adapter as well, allowing users to access the Internet without requiring any wires.
While laptops can be powerful and convenient, the convenience often comes at a price. Most laptops cost several hundred dollars more than a similarly equipped desktop model with a monitor, keyboard, and mouse. Furthermore, working long hours on a laptop with a small screen and keyboard may be more fatiguing than working on a desktop system. Therefore, if portability is not a requirement for your computer, you may find better value in a desktop model.
The desktop is the primary user interface of a computer. When you boot up your computer, the desktop is displayed once the startup process is complete. It includes the desktop background (or wallpaper) and icons of files and folders you may have saved to the desktop. In Windows, the desktop includes a task bar, which is located at the bottom of the screen by default. In Mac OS X, the desktop includes a menu bar at the top of the screen and the Dock at the bottom.
The desktop is visible on both Windows and Macintosh computers as long as an application or window is not filling up the entire screen. You can drag items to and from the desktop, just like a folder. Since the desktop is always present, items on the desktop can be accessed quickly, rather than requiring you to navigate through several directories. Therefore, it may be helpful to store commonly used files, folders, and application shortcuts on your desktop.
Both the Windows and Macintosh operating systems allow you to customize the appearance of your desktop. In Windows 7, you can change the desktop background and select the default desktop icons within the “Personalization” control panel. In Mac OS X 10.6, you can change the desktop background using the “Desktop & Screen Saver” system preference.
