Desktop computers are powerful computing devices designed for regular use at a single location. They typically consist of a monitor, keyboard, mouse, and a central processing unit (CPU) housed in a case. These systems are favored for their performance, upgradeability, and larger screens compared to laptops. With a variety of configurations available, desktop computers cater to different needs, from basic tasks like web browsing and document editing to more demanding applications such as gaming and graphic design. They often provide better performance for the price compared to laptops, making them a popular choice for both home and office environments.
