Computer Fundamentals Notes PDF

The computer is a powerful electronic device that can receive information or data and perform various operations to create results in the form of output. Understanding computer fundamentals is crucial, as this makes computers essential machines for solving problems and manipulating data easily. By accepting and processing data through mathematical and logical operations, it provides us with the output we desire.

Computer Fundamentals Notes – Components

Key Parts of a Computer

A computer can be described better through the functions it performs. Here are its primary operations:

• Input: This is the process of entering data and programs into the computer.
• Control Unit (CU): The Control Unit supervises the processes of input, output, processing, and storage. It decides when to start and stop data input, where to store it, and manages step-by-step operations inside the computer.
• Memory Unit: This part is used to store data and instructions.
• Arithmetic Logic Unit (ALU): The ALU performs major operations such as addition, subtraction, multiplication, division, logical operations, and comparison.
• Output: This process involves producing results from the data to obtain useful information.
