WebbThere are eight 16-bit general-purpose registers: AX, BX, CX, DX, BP, SI, DI, and SP; and you can place any value in them that may be expressed in 16 bits or fewer. When Intel expanded the x86 architecture to 32 bits in 1986, it doubled the size of all eight registers and gave them new names by prefixing an E in front of each register name ... WebbNormalized Segment:Offset Notation . Since there are so many different ways that a single byte in Memory might be referenced using Segment:Offset pairs, most programmers have agreed to use the same convention to normalize all such pairs into values that will always be unique.These unique pairs are called a Normalized Address or Pointer.
