The byte keyword specifies an 8-bit data item.
A byte data item does not undergo any conversion for transmission on the network as a char type can.
The byte type is one of the base types of the interface definition language (IDL). The byte type can appear as a type specifier in const declarations, typedef declarations, general declarations, and function declarators (as a function-return-type specifier and as a parameter-type specifier). For the context in which type specifiers appear, see IDL.
