FourByte
Fourbyte is a term used in computing to describe a data unit composed of four bytes, totaling 32 bits. This size appears in a variety of contexts, including 32-bit integers (signed or unsigned), packed color values such as RGBA, timestamps, and fields in network protocols. The interpretation of a four-byte value depends on the surrounding data type and on endianness, since little-endian systems store the least significant byte first and big-endian systems store the most significant byte first.
In file formats and multimedia, four-byte values often serve as identifiers or length fields. A common convention
