What is the function of a GPU in a computer system?

The function of a GPU, or Graphics Processing Unit, in a computer system is primarily to enhance gaming graphics and improve the rendering of images, animations, and videos. It is designed to handle the intricacies of graphics processing much more efficiently than a CPU (Central Processing Unit). This includes tasks such as rendering 3D images, processing graphical data, and executing complex visual tasks, all of which are crucial for immersive gaming experiences and graphic-intensive applications.

While options related to managing thermal performance, facilitating network connections, and increasing storage capacity address essential functions within a computer, they do not pertain to the specific role a GPU plays. Thermal management is usually within the realm of cooling systems, networking functionalities involve network interface cards or integrated controllers, and storage capacity is influenced by hard drives and solid-state drives rather than a GPU's functions. Thus, the primary role of the GPU is indeed to enhance gaming graphics, making it the correct answer.
