Answer / sysprog
The content of a base register is added to a displacement, and/or to the content of an index register, thereby to determine the address of the source or destination memory location upon which the instruction is to act.
When 0 is specified in the base regester position in an instruction, it is not interpreted by the assembler or the machine as a base register or as referencing register 0; in that position it means no base register for that instruction.
A program base register is used in specifying addesses of memory areas within the program, including instructions and storage areas.

This is why you should only hire American programmers that
actually know what they are doing. Enough of the answers
are wrong that it makes me wonder why we think we get our
money's worth when we hire offshore "talent".
Read the IBM z/OS manuals to get the real answer.

Answer / x506
In 16-bit mode, the base register, EBX, acts as a general-purpose pointer. Besides the specialized ESI, EDI, and EBP registers, it is the only general-purpose register that can appear in a square-bracket memory access (For example, MOV [BX], AX). In the 32-bit world, however, any register may serve as a memory offset, so the base register is no longer special.

Base registers are the registers which are used for data movements. It has special adressing abilities. It holds that adress of data which tells that where the data was stored before execution.
