Based on the register and memory contents specified, find the value of the operand for the “Relative Addressing Mode”
Assume that the contents of the registers E, A, B0 and Y appear as follows:
What is the value register A after completing one in the following flow-chart?
The memory map below gives the contents of each of the locations of a simple memory. Each of these locations uses 4-bit addresses and contains a 4-bit binary value. Write the value accessed from memory and loaded into R0 after executing the following instruction. Assume that r1 initially contains 0001 and r2 contains 001 1
LOAD R0, [R1, R2]
Address Memory contents
Write down the shortest path between switch S3 and switch S1.
Visited | Node | |||||
B | C | D | E | F | G | |
A | 1 | 4 | 5 | - | - | - |
AB | x | y | z | - | - | - |

The above table table is prepared by using the Dijkstra’s algorithm applied to a 7th node G starting from node A.
What is the value of x,y and z in this table after visiting the nodes B,C and D.
