Computer Fundamentals Notes - Summary

The computer is an electronic device that can receive information or data and perform various operations, creating results in the form of output. This makes the computer an essential machine for solving problems and manipulating data. By accepting and processing data through mathematical and logical operations, it provides us with the desired output.

A computer can be understood better by looking at the functions it performs. Specifically, a computer can i) accept data, ii) store data, iii) process data as needed, iv) retrieve stored data whenever required, and v) print the results in a format we want. The major characteristics of a computer include high speed, accuracy, diligence, versatility, and significant storage capacity.

Computer Fundamentals Notes – Components

Key Parts of a Computer

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.
