A desktop computer is a personal computing device designed to be used at a fixed location, typically on a desk. It consists of several components, including a monitor, keyboard, mouse, and a central processing unit (CPU) housed in a case. Desktop computers are commonly used for tasks such as browsing the internet, creating documents, and playing games. These computers often offer more power and storage than portable devices like laptops or tablets. They can be customized with various hardware components, such as graphics cards and additional memory, to enhance performance for specific tasks, including gaming or graphic design.
