Regarding byte order: A layman’s explanation Host Order, Network Order, observed directly via debugger
In the field of computer science, certain design habits have formed due to historical reasons, just like the width of a hip dictates the width of a rocket’s thrusters – there’s no need to rigidly analyze their “advantages” and “disadvantages”; it’s simply a matter of historical convention.
Throughout the history of computer development, there has been no unified standard for data storage. There are two commonly used rules for byte arrangement. For example, if the low-order bits of a multi-digit number are placed at smaller addresses and the high-order bits are placed at larger addresses, it is referred to as little-endian; conversely, it is called big-endian. In network applications, byte order is a factor that must be considered because different types of machines may adopt different standards, so they are all converted according to the network standard. According to reading habits, big-endian byte order is more consistent with the left-to-right reading order.
