 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]]
-[[Fixed-Point Number Representation]]
 [[Floating-Point representation]]
-[[Parity Check]]
+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.
-[[Error detection and correction]]
+[[BCD encoding]]
-[[Reed-Solomon codes]]
+Representing each decimal digit (0-9) with a 4-bit binary sequence, BCD simplifies conversion between binary and decimal
-[[Huffman codes]]
+[[Parity Check]]
-[[RLE coding]]
+A simple error detection method used in data transmission and storage, ensuring data integrity by verifying the even or odd number of 1 bits in binary sequences.
-[[LZW coding]]
+[[Error detection and correction]]
-[[Multimedia compression]]
-[[Jpeg compression]]
+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
-[[Mpeg compression]]
+[[Checksum]]
-[[Character encoding]]
+A checksum is a small value calculated from a sequence of data. It helps us detect accidental changes during storage or transmission.
-[[UTF-8 encoding]]
+[[Luhn algortithm to protect Credit card numbers|Luhn algorithm to protect Credit card numbers]]
-[[Base64 coding]]
+We can use the Luhn algorithm to check if a credit card number is valid.
