 Explains various methods for encoding integers, focusing on binary representation and how to handle both positive and negative numbers using sign-magnitude and two's complement methods. It includes practical examples, such as converting between decimal and binary systems and performing arithmetic with binary numbers.
-[[BCD encoding]]
-Representing each decimal digit (0-9) with a 4-bit binary sequence, BCD simplifies conversion between binary and decimal
-[[Fixed-Point Number Representation]]
-A method for encoding real numbers where the decimal point's position is fixed, offering hardware simplicity and uniform precision.
 [[Floating-Point representation]]
 Explains how real numbers are stored using the IEEE 754 standard. The number is divided into sign, exponent, and mantissa for efficient handling of large or small values.

 Techniques like Elias-style block protection and Hamming codes are explained, focusing on detecting and correcting single-bit errors to maintain data integrity during transmission
+[[Checksum]]
+A checksum is a small value calculated from a sequence of data. It helps us detect accidental changes during storage or transmission.
