Why Your Computer Reads Numbers Backwards: Byte Order Explained
The article explains the concept of byte order, or endianness, which determines how computers store multi-byte numbers in memory. It describes two types: little endian, where the least significant byte is stored first, and big endian, where the most significant byte comes first. These storage methods affect how data is interpreted across different computer architectures.
- ▪Byte order, also known as endianness, refers to the order in which bytes are stored in memory for multi-byte data types.
- ▪In little endian systems, the least significant byte is stored at the lowest memory address.
- ▪In big endian systems, the most significant byte is stored at the lowest memory address.
- ▪The number 0x12345678 would be stored as 78 56 34 12 in little endian and 12 34 56 78 in big endian.
- ▪Endianness impacts data interpretation, especially in cross-platform computing and networking.
