 ===== Parity Check =====
-A parity check is a simple error detection mechanism used in digital communication and data storage to detect errors in transmitted or stored data. It ensures that the number of bits with a value of 1 in a binary sequence is either even or odd, depending on the type of parity used.
+A parity check is a simple **error detection** mechanism used in digital communication and data storage to **detect errors** in transmitted or stored data. It ensures that the number of bits with a value of 1 in a binary sequence is either even or odd, depending on the type of parity used.
 There are two types of parity:

   * **Limited error detection**: Parity checks can only detect single-bit errors (if one bit flips). It cannot detect multi-bit errors, where two or more bits are changed.
   * **No error correction**: Parity checks only detect errors but cannot correct them. For correction, more advanced techniques like Hamming codes.
+Let's see a C code to check 8 bits parity.
