Study Notes

Hardware Components

Hardware refers to the physical components of a computer that perform input, processing, output, and storage activities.

CPU (Microprocessor)

The central processing unit (CPU) performs actual computation inside any computer.
The CPU is a microprocessor made up of millions of microscopic transistors embedded on a chip.

Parts of a Computer

Central Processing Unit (CPU): Manipulates data and controls tasks performed by other components.
Primary Storage: Temporarily stores data and program instructions during processing.
Secondary Storage: Stores data and programs for future use.
Input Technologies: Accept data and instructions, converting them to a form the computer can understand.
Output Technologies: Present data and information in a form people can understand.
Communication Technologies: Provide for the flow of data from external computer networks to the CPU and from the CPU to computer networks.

Input Technologies

Input technologies allow users to enter data into a computer.
Data can be of different types, including numeric, text, multimedia (images, video, and sound).
Each data type has its suitable input technologies.
Two main types of input devices: • Human data-entry devices (require human effort to input data): Examples include keyboard, mouse, touch screen, and voice recognition. • Source-data automation devices (input data with minimal human intervention): Examples include bar code readers.

Output Technologies

Output generated by a computer can be transmitted to the user via several output devices.
Output devices include monitors, printers, and plotters.

Central Processing Unit (CPU)

The CPU has different parts, which perform different functions: • Control unit: sequentially accesses program instructions, decodes them, and controls the flow of data. • Arithmetic-Logic Unit (ALU). • Registers.
