Dword byte size
WebAug 18, 2024 · A byte is a unit of data storage capacity. One byte is equal to 8 bits. The term was coined in 1959 by John Backus at IBM. He defined a byte as eight bits (1 bit 0 or 1). This means that each byte has two binary digits (bits) and can store 256 values (2^8 256). Word A computer word is a grouping of bits, similar to a byte. WebBytes words and dwords are the basic chunks of data used in programming. The processor will work with the data size to suit the instruction it is executing.
