How can I convert Little Endian to Big Endian?

To convert data between Little Endian and Big Endian formats, you need to reverse the byte order of the data. Endianness defines how multi-byte data types (like integers) are stored in memory:

• Little Endian: The least significant byte (LSB) is stored first.
• Big Endian: The most significant byte (MSB) is stored first.

Conceptual Steps:

1. Understand the Input Format:
   • Identify the byte sequence to convert.
   • Ensure you know its size (e.g., 16-bit, 32-bit, etc.).
2. Reverse the Byte Order:
   • Split the input data into individual bytes.
   • Reverse the sequence of bytes.
3. Output the Data:
   • Assemble the reversed bytes into the desired format.

Example Workflow:

• For a 32-bit integer represented as 4 bytes: [0x12, 0x34, 0x56, 0x78]:
  • Little Endian stores it as: 0x78 0x56 0x34 0x12.
  • Big Endian stores it as: 0x12 0x34 0x56 0x78.

To convert:

• Reverse the order from [0x78, 0x56, 0x34, 0x12] to [0x12, 0x34, 0x56, 0x78].

Notes:

• Use built-in utilities or functions (in languages like Python, C, or Java) to automate byte-order conversions when dealing with binary data.
• Ensure you know the endianness of the system you’re working on if you’re performing conversions manually.
