Question

In a $8088$ microprocessor each CPU register is _____.

• A. $12$ bits long
• B. $16$ bits long
• C. $8$ bits long
• D. $8$ bytes long

Answer 1

Answer: (B)

$16$ bits long

In a 8088 microprocessor each CPU register is 16 bits long.

Microprocessor:-

A microprocessor is a computer processor on a microchip. The microprocessor contains all, or most of, the central processing unit (CPU) functions and is the "engine" that goes into motion when you turn your computer on.

CPU register:-

The term is often used to refer only to the group of registers that can be directly indexed for input or output of an instruction, as defined by the instruction set. For instance, the x86 instruction set defines a set of eight 32-bit registers, but a CPU that implements the X86 instruction set will contain many more hardware registers than just these eight.
