11.#2�s complement of -13 = 11110011 Add the two numbers in their 2�s complement form, including their sign bits and discard any carry out of the sign (leftmost) bit position. So the answer is 11101101 (-19). -6 11111010 -13 11110011 ---------------------- -19 11101101 #6. Which one of the following CPU registers holds the address of the instructions (instructions in the program stored in memory) to be executed next?
|MAR (Memory address register)|
|MBR (Memory Buffer Register)|
|IR (Instruction Register)|
|PC (Program Counter).|
ANSWER : 5 PC (Program Counter).
Explanation : : Program Counter (PC) keeps track of the instruction of the program stored in memory.
12.Information transfer from one register to another is designated in symbolic form by means of
ANSWER : 4 Replacement Operator
Explanation : : A replacement operator consisting of the information transfer from one register to another, is designated in symbolic form.
13.The simplest way to determine cache locations in which to store memory blocks is the,
|Associative Mapping technique|
|Direct Mapping technique|
|Set-Associative Mapping technique|
|Indirect Mapping technique|
ANSWER : 2 Direct Mapping technique
Explanation : : Associative memories are expensive compared to random-access memories because of the added logic associated with each cell. Therefore, the simplest way to determine cache locations in which to store memory blocks is the Direct Mapping.
