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, making them ideal for tasks such as gaming, graphic design, and office work. Unlike laptops, desktop computers offer more customization options and often provide better performance for the price. They are widely used in homes, schools, and businesses, providing users with a reliable platform for productivity and entertainment. Popular brands include Dell, HP, and Apple.
