Understanding Data Types: Precision, Storage, and Representation in Programming

This article explores various data types used in programming, focusing on precision and storage requirements. It covers high precision and low precision types, including integers and real numbers, along with their byte storage representations, such as 1-bit, 1-byte, and complex variables. The text delves into ASCII character representation and logical values, offering examples like "HOLA" and numeric values like "1234". Understanding these fundamentals is essential for efficient programming and data management.
