What is Next Fit?
The next fit is a modified version of ‘first fit’. It begins as the first fit to find a free partition but when called next time it starts searching from where it left off, not from the beginning. This policy makes use of a roving pointer. The pointer moves along the memory chain to search for the next fit. This helps in, to avoid the usage of memory always from the head (beginning) of the free blockchain.
