Fifo disk scheduling
http://www.cs.iit.edu/~cs561/cs450/disksched/disksched.html WebThe simplest form of disk scheduling is, of course, the (FIFO) algorithm. This algorithm is intrinsically fair, but it generally does not provide the fastest service. SCAN. In the SCAN algorithm, the disk arm starts at one end, and moves towards the other end, servicing requests as it reaches each cylinder, until it gets to the other end of the ...
