An operating system follows a variable memory partitioning model. The system keeps track of empty blocks in a linked list in the order of their address, where each node stores the size of next empty block in the memory. Say that current state of the memory is hold by the linked list shown below, which tells that there are currently four empty blocks in the memory, and the size of first block is 12 byte etc. Assume that following memory block requests have been made in given order: 8 bytes, 2 bytes and 6 bytes. Draw the linked list to be changed after each block assignment by the following

Question

An operating system follows a variable memory partitioning model. The system keeps track of empty blocks in a linked list in the order of their address, where each node stores the size of next empty block in the memory. Say that current state of the memory is hold by the linked list shown below, which tells that there are currently four empty blocks in the memory, and the size of first block is 12 byte etc.

Assume that following memory block requests have been made in given order: 8 bytes, 2 bytes and 6 bytes. Draw the linked list to be changed after each block assignment by the following strategies ;
