The CPU is arguably the most important piece of hardware. The Central Processing Unit is the part of the computer where the searching and sorting of data, calculating, and decision-making goes on. It is often called the "brain" of the computer because all processing activities are carried out inside it. The CPU consists of three main components: The PSU converts electrical power from an outlet
: These allow you to enter data. Common examples include the keyboard, mouse, microphone, and image scanner .
: Known as the processor, this unit executes arithmetic and logical operations, serving as the primary control center for all computer tasks. : Saving data permanently or temporarily for future access
Computer memory is a hierarchy of storage with varying speeds, volatility, and purposes.
Every presentation should start with a fundamental definition of a computer. According to curriculum standards, a computer is "an electronic device that accepts input, processes it according to a series of instructions (called computer programs or software), and produces output". This definition is the foundation upon which all hardware concepts are built.
