A micro‑controller development board is equipped with a 16‑bit address bus and an 8‑bit data bus. The system uses byte addressing (each address refers to one byte). You are to allocate memory for two data structures: - A character array of 2 048 bytes. - A lookup table of 4 096 bytes. Both structures must be placed in the same memory space without overlapping. The array is to be placed at the lowest available address and the lookup table immediately after the array. Using this information, answer the following:

Question Parts

( a )
State the starting and ending hexadecimal addresses of the character array.
( b )
State the starting and ending hexadecimal addresses of the lookup table.
( c )
What is the highest memory address used by the two structures combined?
( d )
Given that the address bus is 16‑bit, determine the minimum number of address‑line bits that could be permanently tied to 0 (i.e., not used) while still being able to address both structures without overlap.
( e )
Sketch a simple memory‑map diagram (describe it in words) showing the two structures and the unused address range.
