- ___________ occurs when the result of an arithmetic operation exceeds the number of bits available to store it.A PDA has "XY" MB of memory, Where XY are the last two numbers of your student number (e.g for 2021789, the number is in red ). How many bits are needed to address any single byte in of its memory? Show your calculation steps Further instructions While typing use ^ instead of power e.g 2^3 = 8 In this question You must apply your knowledge of various memory measurement units e.g how many Bytes in a KB, how many KB in MB etc. You are advised to use "toolbar toggle"available in your text box for editing your calculationsIf the value 8 is stored in the memory cell corresponding to the address 5, what is the practical difference between writing the value 5 into cell number 6 and copying the contents of cell number 5 into cell number 6?
