General Purpose Registers (AX,BX,CX,DX,SP,BP,SI,DI) and ALU in Intel 8086


General Purpose Registers:

In computer architecture, a processor register is a quickly accessible location available to a computer's central processing unit (CPU). Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only. Registers are normally measured by the number of bits they can hold, for example, an "8-bit register", "32-bit register" or a "64-bit register" (or even with more bits).

General Registers or General Purpose Registers are a kind of registers which can store both data and addresses. All general registers of the intel 8086 microprocessor can be used for arithmetic and logic operations.
