Q:

Why the temporary registers W and Z are named so i mean we start from A, B, C, D, E then H and L coz H stands for higher bit and L for lower bit of the address pinted by memory pointer.. but wats W and Z for?

Answer

As W and Z alphabets are not widely used similarly as W and Z is internally used they would have been named so

Q:

What is logical and physical addresses space?

Answer

Logical address space is generated from CPU; it bound to a separate physical address space is central to proper memory management. Physical address space is seen by the memory unit. Logical address space is virtual address space. Both these address space will be same at compile time but differ at execution time.

Q:

In loading programs into memory, what is the difference between load-time dynamic linking and run-time dynamic linking?

Answer

For load-time dynamic linking: Load module to be loaded is read into memory. Any reference to a target external module causes that module to be loaded and the references are updated to a relative address from the start base address of the application module.


With run-time dynamic loading: Some of the linking is postponed until actual reference during execution. Then the correct module is loaded and linked.

Q:

What are the minimal cost and minimal risk solution?

Answer

In binary representation there are some states that believed to be never occurred due to some particular functionality of a given circuit. If zero output is assigned to such states then it is called minimal risk solution as  we are resetting the formidable states which could be occurred accidentally. Another approach is to assigned a don't care to them so it results in lesser logic and hence is called minimal cost solution.
