Characteristics of a Desktop Computer

• Intended for Use on a Desk or Table: Desktop computers are specifically designed to be stationed on a desk or table, making them ideal for use in a fixed location such as a home office or workplace.
• Consists of Separate Components: A typical desktop setup includes distinct components like a monitor, keyboard, mouse, and a central processing unit (CPU) housed in a tower. These parts are physically separate and connected by various cables.
• Higher Performance Compared to Laptops and Tablets: Desktops generally offer superior performance capabilities, boasting more powerful processors, greater memory capacity, and enhanced graphics capabilities, which makes them suitable for demanding tasks such as gaming, video editing, and software development.
• Greater Ease of Upgrading and Customization: Desktops are known for their modular nature, allowing users to easily upgrade individual components like RAM, storage, graphics cards, and even the CPU. This makes it convenient to enhance the system's performance or replace faulty parts.
• Reduced Portability Compared to Other Computers: Due to their larger size and the fact that they consist of multiple, separate components, desktop computers are not designed for portability. They are much less convenient to move around compared to laptops and tablets, which are built for mobility.
