What is the minimum number of address bus bits required to directly access 1 MB ($2^{20}$ bytes) of physical memory?
In 8088/8086 segmented memory architecture, which pointer register is associated by default with the Code Segment (`CS`) register?
True or False: In 16-bit 8088 addressing modes, combining two base registers in indirect memory addressing (such as `[BX + BP]`) is illegal.
In 8088/8086 segmented memory architecture, which register is associated by default with the Code Segment (`CS`) register to fetch instructions?
All memory addressing mechanisms in the iAPX88 architecture evaluate and return a 16-bit offset number called the __________.
In direct addressing mode, the memory displacement/address supplied explicitly within the instruction opcode stream is __________.
True or False: In 16-bit x86 memory addressing modes, subtracting an index register from a base register (such as `[BX - SI]`) within memory address brackets is illegal in assembly language.
In direct addressing mode, the memory address offset specified in the instruction is __________.
