What are the primary components housed within a system unit?

The primary components housed within a system unit include the CPU, memory, and storage devices. The CPU, or Central Processing Unit, is often referred to as the brain of the computer, executing instructions and processing data. Memory, specifically RAM (Random Access Memory), provides the temporary storage needed for processing tasks and running applications. Storage devices, such as hard drives or SSDs (Solid State Drives), are responsible for saving data and files long-term.

These components are integral to the system unit because they work together to perform computations, store and retrieve information, and facilitate the overall functioning of the computer. Understanding these core components is essential for grasping how computers operate and how various processes are managed within the system. The other options, while related to computing, pertain to external devices or software rather than the physical architecture contained within the system unit itself.
