3. Give at least three digital components and briefly describe their applications

1. CPU (Central Processing Unit): The CPU is the primary component of a computer system and is responsible for executing instructions and performing calculations. It acts as the brain of the computer and is essential for running applications, handling data processing, and controlling the overall functionality of the system.

2. GPU (Graphics Processing Unit): The GPU is a specialized processor designed to handle graphics rendering and image processing tasks. It is commonly used in gaming PCs, video editing workstations, and other graphics-intensive applications to enhance visual performance and improve image quality.

3. RAM (Random Access Memory): RAM is a type of volatile memory that stores data and program instructions temporarily while the computer is in use. It allows for quick access to frequently used information, which helps speed up the processing and execution of tasks. RAM is essential for multitasking and running multiple applications simultaneously.
