What is considered an internal component of a computer?

The central processing unit (CPU) is considered an internal component of a computer because it is housed within the computer's case and is a critical part of the system’s architecture. The CPU processes instructions, performs calculations, and manages data flow within the computer. It operates at high speed and is often referred to as the "brain" of the computer, as it is responsible for executing programs and managing the operations of other internal components.

In contrast, external components such as a monitor, printer, and keyboard are considered peripheral devices. They connect to the computer but do not reside within its primary enclosure. The monitor displays output, the printer produces hard copies of documents, and the keyboard allows the user to input data into the system. These peripherals are essential for interacting with the computer but are not part of the internal workings that facilitate computing operations.
