1. In a system using the relocatable dynamic partitions scheme, given the following situation (and using decimal form): Job Q is loaded into memory starting at memory location 42K.a. Calculate the exact starting address for Job Q in bytes.b. If the memory block has 3K in fragmentation, calculate the size of the memory block.c. Is the resulting fragmentation internal or external? Explain your reasoning.2. Given the following information:Job List: Memory Block List:Job Number Memory Requested Memory Block Memory Block SizeJob A 57K Block 1 900K (low-order memory)Job B 920K Block 2 910KJob C 50K Block 3 200KJob D 701k Block 4 300k (high-order memory)a. Use the first-fit algorithm to indicate which memory blocks are allocated to each of the three arriving jobs.b. Use the best-fit algorithm to indicate which memory blocks are allocated to each of the three arriving jobs.3. if the relocation register holds the value of -83968, was the relocated job moved towards the lower or higher addressable end of main memory? By how many kilobytes was it moved? Explain your conclusion.4. in a system using the dynamic partition memory allocation scheme given the following situation (and using decimal form) after job C of size 70k is loaded into a partition resulting in 7k of fragmentation, calculate the size (in bytes) of its partition and identify the type of fragmentation that is caused. Explain your answer.
