"Big-endian" is a term used to describe a particular order of bytes in computer data architecture where the most significant byte is stored in the smallest memory address. However, there are alternative synonyms that can be utilized to convey the same concept. One example is "MSB-first", where MSB stands for Most Significant Bit. This term highlights the emphasis on the uppermost bit in a byte sequence. Additionally, "network byte order" can be employed as a synonym for big-endian. This phrase signifies the standard byte ordering system used in network protocols. These terms are interchangeable and serve to illustrate the byte arrangement in computer systems.
