Question

What is the purpose of a register in low-level data management?

a.

To store data that is used by the operating system

b.

To store global variables

c.

To store local variables and function parameters

d.

To store data that is used by the CPU for fast access

Posted under Reverse Engineering

Answer: (d).To store data that is used by the CPU for fast access Explanation:Registers are small, fast-access memory locations within the CPU that are used to store data that is needed by the processor for immediate computations. Registers are used to improve program performance by minimizing the amount of time required to access data from main memory.
