Why would using fixed partitions in a current operating systems (Windows, Mac OS, Linux, etc.) be a big mistake? Provide at least two (2) reasons.What are some advantages and disadvantages of fixed partitions and dynamic partitions? List at least one (1) advantage and disadvantage for each.Advantages of fixed partitions are that it has big enough memory for the partition to work A disadvatage of fixed partition is that An advtage of dynamic partition is that Disadvantages of dynamic partitions is that it has memory allocations which means that if a new process needs to be made then it would skip the previous allocations and make a new one to be able to support the new process. What is the primary problem associated with fragmentation (internal or external)?Why might internal fragmentation be worse than external fragmentation? Provide at least two (2) reasons.It might be worse because memory blocks are of fixed size and processes assigned to them may not need the full memory amount. Also, the Internal fragmentation uses more memory to be wasted. Can internal fragmentation occur when using fixed partitions?Yes, because memory blocks are fixed size and if a new process was to be made, it would not use or need the full memory.Can external fragmentation occur when using fixed partitions?No, because the memory blocks can not be allocated which means that internal fragmentation also can’t be allocated. Can internal fragmentation occur when using dynamic partitions?No, because the memory block is the same as the memory block assigned.Can external fragmentation occur when using dynamic partitions?Yes, because the switching processes are noncontiguous.What are some advantages and disadvantages of the First-Fit memory allocation algorithm? List at least one (1) advantage and disadvantage.An advantage that the First Fit has is that it finds and searches the size for memory allocation that needs to be used and saves time by taking less time to search. A disadvantage of First Fit is that it is a more internal fragmentation. It needs to categorize everything from the beginning. What are some advantages and disadvantages of the Best-Fit memory allocation algorithm? List at least one (1) advantage and disadvantage.An advantage of Best Fit is that it finds and searches by allocating by memory and stacks them instantly.A disadvantage is that it is slower than the First Fit memory allocation algorithm.
