Calculate the exact starting address for job Q in bytes.

Job list:

Job Number

Memory requested Memory block list:

Memory Block

Memory block size
Job A 690k Block 1 900k(low-order memory)
Job B 275k Block 2 910k
Job C 760k Block 3 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.

 

 

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.
