A modern desktop computer usually has at least one central processing unit (CPU), one or more graphics processing units (GPUs), and a memory controller. In the case of a gaming laptop, an additional graphics chip may also be present, providing specialized graphics rendering capabilities for gaming.[1] A desktop computer typically has a number of slots for expansion cards. A gaming laptop may have as many as four, allowing for additional high-performance graphics cards, memory cards, and storage devices.
The number of slots is not always indicative of the amount of available graphics power or storage capacity. A laptop with a weaker GPU may have only one or two expansion slots, while a laptop with an ultra-powerful GPU may have four or more.
The central processing unit (CPU) is the key component of a computer system. The CPU performs all the basic operations of the computer: interpreting and executing instructions written in code. It is responsible for handling all data processing tasks (including running programs), controlling basic system operations, and interfacing with peripherals.
Many laptops also have a graphics processing unit (GPU) to handle complex 3D graphics rendering and other tasks. GPUs are very powerful chips that can handle many calculations at once.
Some laptops also include extra memory slots to expand memory beyond what is available on the mainboard. This extra memory can be used for temporary storage or as a pool of resources for running programs simultaneously.
Some gaming laptops include special built-in software that allows them to use additional memory cards to increase their storage capacity even further.
